1. GENERAL DESCRIPTION
W83627THF is a Winbond LPC I/O product. It integrates the following major peripheral functions in a chip: the disk driver adapter (FDC), serial port (UART), parallel port (SPP/EPP/ECP), keyboard controller (KBC), SIR, game port, MIDI port, hardware monitor, ACPI, On Now Wake-Up features. The disk drive adapter functions of W83627THF include a floppy disk drive controller compatible with the industry standard 82077/765, data separator, write pre-compensation circuit, decode logic, data rate selection, clock generator, drive interface control logic, and interrupt and DMA logic. The wide range of functions integrated onto the W83627THF greatly reduces the number of components required for interfacing with floppy disk drives. The W83627THF supports four 360K, 720K, 1.2M, 1.44M, or 2.88M disk drives and data transfer rates of 250 Kb/s, 300 Kb/s, 500 Kb/s, 1 Mb/s, and 2 Mb/s. The W83627THF provides two high-speed serial communication ports (UARTs), one of which supports serial Infrared communication. Each UART includes a 16-byte send/receive FIFO, a programmable baud rate generator, complete modem control capability, and a processor interrupts system. Both UARTs provide legacy speed with baud rate up to 115.2k bps and also advanced speed with baud rates of 230k, 460k, or 921k bps, which support higher speed modems. In addition, the W83627THF provides IR functions: IrDA 1.0 (SIR for 1.152K bps) The W83627THF supports one PC-compatible printer port (SPP), Bi-directional Printer port (BPP) and also Enhanced Parallel Port (EPP) and Extended Capabilities Port (ECP). Through the printer port interface pins, also available are: Extension FDD Mode and Extension 2FDD Mode allowing one or two external floppy disk drives to be connected. The configuration registers support mode selection, function enable/disable, and power down function selection. Furthermore, the configurable PnP features are compatible with the plug-and-play feature demand of Windows 95/98TM, which makes system resource allocation more efficient than ever.
The W83627THF provides functions that complies with ACPI (Advanced Configuration and Power Interface), which includes support of legacy and ACPI power management through PME# or PSOUT#

, or customer code.
The W83627THF provides a set of flexible I/O control functions to the system designer through a set of General Purpose I/O ports. These GPIO ports may serve as simple I/O or may be individually configured to provide a predefined alternate function. The W83627THF is made to fully comply with Microsoft PC98 and PC99 Hardware Design Guide. Moreover, W83627THF is made to meet the specification of PC2001's requirement in the power management: ACPI 1.0/1.0b/2.0 and DPM (Device Power Management). The W83627THF contains a game port and a MIDI port. The game port is designed to support 2 joysticks and can be applied to all standard PC game control devices. They are very important for an entertainment or consumer computer. The W83627THF supports hardware status monitoring for personal computers. It can be used to monitor several critical hardware parameters of the system, including power supply voltages, fan speeds, and temperatures, which are very important for a high-end computer system to work stably and properly. Moreover, W83627THF support the Smart Fan control system, including the "Thermal CruiseTM" and "Speed CruiseTM" functions. Smart Fan can make system more stable and user friendly. The special characteristic of Super I/O product line is to avoid power rails short. This is especially true to a multi-power system where power partition is much more complex than a single-power one. Special care might be applied during layout stage or the IC will fail even though its intended function is OK.

4. GENERAL PURPOSE I/O
W83627THF provides 36 input/output ports that can be individually configured to perform a simple basic I/O function or a pre-defined alternate function. Those 36 GP I/O ports are divided into five groups . The first and fifth groups are configured through control registers in logical device 7, the second group in logical device 8, and the third and forth groups in logical device 9. Users can configure each individual port to be an input or output port by programming respective bit in selection register (CRF0/F3: 0 = output, 1 = input). Invert port value by setting inversion register (CRF2/F5: 0 = non-inverse, 1 = inverse). Port value is read/written through data register (CRF1/CRF4). Table 2.1 and 2.2 gives more details on GPIO's assignment. Figure 2-1 shows the GP I/O port's structure. After Power-on reset, those ports default to perform basic input function which maintains its previous settings until a battery loss condition.

HARDWARE MONITOR
General Description
The W83627THF can be used to monitor several critical hardware parameters of the system, including power supply voltages, fan speeds, and temperatures, which are very important for a high-end computer system to work stable and properly. W83627THF provides LPC interface to access hardware . An 8-bit analog-to-digital converter (ADC) was built inside W83627THF. The W83627THF can simultaneously monitor 3 analog voltage inputs (addition monitor VBAT, 5VSB & 5VCC power), 3 fan tachometer inputs, 3 remote temperature inputs and one case-open detection signal. The remote temperature sensing can be performed by thermistors, 2N3904 NPN-type transistors, or directly from IntelTM CPU thermal diode output. Also the W83627THF provides: 3 analog outputs for fan speed control. Beep tone output for warning; SMI#(through Serial IRQ pin), OVT# signals for system protection events. Through the application software or BIOS, the users can read all the monitored parameters of system from time to time. And a pop-up warning can be also activated when the monitored item was out of the proper/preset range. The application software could be Winbond's Hardware DoctorTM, or IntelTM LDCM (LanDesk Client Management), or other management application software. Also the users can set up the upper and lower limits (alarm thresholds) of these monitored parameters and to activate one programmable and maskable interrupts. An optional beep tone could be used as warning signal when the monitored parameters is out of the preset range.
5.2
Access Interface
W83627THF uses LPC Bus to access which the ports of low byte (bit2~bit0) are defined in the port 5h and 6h. The other higher bits of these ports is set by W83627THF itself. The general decoded address is set to port 295h and port 296h. These two ports are described as following: Port 295h: Index port.

5.3 Analog Inputs
The maximum input voltage of the analog pin is 4.096V because the 8-bit ADC has a 16mv LSB. Really, the application of the PC monitoring would most often be connected to power suppliers. The CPU Vcore voltage, +3.3V, battery(pin 74), AVCC(pin 114) and 5VSB voltage can directly connected to these analog inputs. The +12V voltage inputs should be reduced a factor with external resistors so as to obtain the input range. As Figure 3.2 shows.

The -12V input voltage can be expressed as following equation.
VIN 0 = (V2 - 3.6) x
R4 + 3.6, whereV2 = -12 R3 + R 4
The value of R3 and R4 can be selected to 56K Ohms and 232K Ohms, respectively, when the input voltage V2 is -12V. The node voltage of VIN0 can be subject to less than 4.096V for the maximum input range of the 8-bit ADC. The Pin 114 is connected to the power supply VCC with +5V. There are two functions in this pin with 5V. The first function is to supply internal analog power in the W83627THF and the second function is that this voltage with 5V is connected to internal serial resistors to monitor the +5V voltage. The W83627THF internal two serial resistors are 34K ohms and 51K ohms so that input voltage to ADC is 3V which is less than 4.096V of ADC maximum input voltage. The express equation can represent as follows.
Vin = VCC x
51K 3V 51K + 34 K
where VCC is set to 5V. The Pin 61 is connected to 5VSB voltage. W83627THF monitors this voltage and the internal two serial resistors are 34K and 51K so that input voltage to ADC is 3V which less than 4.096V of ADC maximum input voltage. 5.3.2 CPUVCORE voltage detection method: W83627THF provides two detection methods for CPUVCORE(pin100). (1). VRM8 method: The LSB of this mode is 16mV. This means that the detected voltage equals to the reading of this voltage register multiplies 16mV. The formula is as the following: Detected Voltage = Re ading 0.016 V (2). VRM9 method: (Default) The LSB of this mode is 4.88mV which is especially designed for the low voltage CPU. The formula is as the following: Detected Voltage = Re ading 0.00488 + 0.69 V

The W83627THF can connect three thermistors to measure three different environment temperature. The specification of thermistor should be considered to (1) value is 3435K, (2) resistor value is 10K ohms at 25C. In the Figure 3-2, the themistor is connected by a serial resistor with 10K Ohms, then connect to VREF (Pin 101). 5.3.3.2 Monitor temperature from Pentium IITM/Pentium IIITM thermal diode or bipolar transistor 2N3904
The W83627THF can alternate the thermistor to Pentium IITM/Pentium IIITM thermal diode interface or transistor 2N3904 and the circuit connection is shown as Figure 3-3. The pin of Pentium IITM/Pentium IIITM D- is connected to AGND and the pin D+ is connected to temperature sensor pin in the W83627THF. The resistor R=30K ohms should be connected to VREF to supply the diode bias current and the bypass capacitor C=3300pF should be added to filter the high frequency noise. The transistor 2N3904 should be connected to a form with a diode, that is, the Base (B) and Collector (C) in the 2N3904 should be tied together to act as a thermal diode.

FAN Speed Count and FAN Speed Control
5.4.1 Fan speed count Inputs are provides for signals from fans equipped with tachometer outputs. The level of these signals should be set to TTL level, and maximum input voltage can't be over VCC. If the input signals from the tachometer outputs are over the VCC, the external trimming circuit should be added to reduce the voltage to obtain the input specification. The normal circuit and trimming circuits are shown as Figure 3-4 ~ 3-7. Determine the fan counter according to:
Count =
1.35 x10 6 RPM x Divisor
In other words, the fan speed counter has been read from register CR28 or CR29 or CR2A, the fan speed can be evaluated by the following equation.
RPM =
1.35 x 10 6 Count x Divisor
The default divisor is 2 and defined at CR47.bit7~4, CR4B.bit7~6, and Bank0 CR5D.bit5~7 which are three bits for divisor. That provides very low speed fan counter such as power supply fan. The followed table is an example for the relation of divisor, RPM, and count .

5.4.2 Fan speed control The W83627THF has a 4 bit DAC which produces 0 to 5 volts DC output that provides maximum 3 sets for fan speed control. The analog output can be programmed in the Bank0 Index 01h, Index 03h and Index 11h. The default value is 0xFY,Y is reserved nibble, that is default output value is 5 V. The expression of output voltage can be represented as follow ,
OUTPUT VOLTAGE = AVCC x

Figure 3-8 Must be take care when choosing the OP-AMP and the transistor. The OP-AMP is used for amplify the 5V range of the DC output up to 12V . The transistor should has a suitable value to avoid its base current pulling down the OP-AMP 's output and gain the common current to operate the fan at fully speed.

SmartFanTM Control
SmartFanTM Control provides two mechanisms. One is Thermal Cruise mode and the other is Fan Speed Cruise mode. 5.5.1 Thermal Cruise mode There are maximum 3 pairs of Temperature/FANOUT control at this mode: SYSTIN with FANOUT1, CPUTIN with FANOUT2, VTIN with FANOUT3. At this mode, W83627THF provides the Smart Fan system which can control the fan speed automatically depend on current temperature to keep it with in a specific range. At first a wanted temperature and interval must be set (ex. 55 C 3 Publication Release Date: May 21, 2003 Revision 0.7

C) by BIOS, as long as the real temperature remains below the setting value, the fan will be off. Once the temperature exceeds the setting high limit temperature ( 58C), the fan will be turned on with a specific speed set by BIOS (ex: 3.75 V) and automatically controlled its DC voltage output with the temperature varying. Three conditions may occur : (1) If the temperature still exceeds the high limit (ex: 58C), DC Fan output voltage will increase slowly. If the fan has been operating in its fully speed but the temperature still exceeds the high limit(ex: 58C) after 3 minutes, a warning message will be issued to protect the system. (2) If the temperature goes below the high limit (ex: 58C), but above the low limit (ex: 52C), the fan speed will be fixed at the current speed because the temperature is in the target area(ex: 52 C ~ 58C). (3) If the temperature goes below the low limit (ex: 52C), DC Fan output voltage will decrease slowly to 0 until the temperature exceeds the low limit. Figure 3-9 and 3-10 give the illustration for Thermal Cruise Mode .

One more protection is provided that DC FAN output voltage will not be decreased to 0 in the above (3) situation in order to keep the fans running with a minimum speed. By setting CR[12h] bit3-5 to 1, FAN output voltage will be decreased to the " Stop Value " which are defined at CR[08h],CR[09h] and CR[15h]. 5.5.2 Fan Speed Cruise mode There are 3 pairs of FANIN/FANOUT control at this mode: FANIN1 with FANOUT1, FANIN2 with FANOUT2, FANIN3 with FANOUT3. At this mode, W83627THF provides the Smart Fan system which can control the fan speed automatically depend on current fan speeds to keep it with in a specific range. A wanted fan speed count and interval must be set (ex. 160 10 ) by BIOS. As long as the fan speed count is the specific range, output voltage will keep the current value. If current fan speed count is higher than the high limit (ex. 160+10), output voltage will be increased to keep the count less than the high limit. Otherwise, if current fan speed is less than the low limit(ex. 160-10), output voltage will be decreased to keep the count higher than the low limit. See Figure 3-11 example.

5.6 SMI# interrupt mode
The SMI#/IRQIN1 pin(pin2) is a multi-function pin. The SMI# function is selected at Configuration Register CR[2Ah] bit 2. 5.6.1 Voltage SMI# mode : SMI# interrupt for voltage is Two-Times Interrupt Mode. Voltage exceeding high limit or going below low limit will causes an interrupt if the previous interrupt has been reset by reading all the interrupt Status Register. (Figure 3-12 ) 5.6.2 Fan SMI# mode : SMI# interrupt for fan is Two-Times Interrupt Mode. Fan count exceeding the limit, or exceeding and then going below the limit, will causes an interrupt if the previous interrupt has been reset by reading all the interrupt Status Register.

5.6.3 The W83627THF temperature sensor 1(SYSTIN) SMI# interrupt has 3 modes: (1) Comparator Interrupt Mode Setting the THYST (Temperature Hysteresis) limit to 127C will set temperature sensor 1 SMI# to the Comparator Interrupt Mode. Temperature exceeds TO (Over Temperature) Limit causes an interrupt and this interrupt will be reset by reading all the Interrupt Status Register. Once an interrupt event has occurred by exceeding TO, then reset, if the temperature remains above the TO , the interrupt will occur again when the next conversion has completed. If an interrupt event has occurred by exceeding TO and not reset, the interrupts will not occur again. The interrupts will continue to occur in this manner until the temperature goes below TO. (Figure 3-14 ) . Setting the THYST lower than TO will set temperature sensor 1 SMI# to the Interrupt Mode. The following are two kinds of interrupt modes, which are selected by Index 4Ch bit5 : (2) Two-Times Interrupt Mode Temperature exceeding TO causes an interrupt and then temperature going below THYST will also cause an interrupt if the previous interrupt has been reset by reading all the interrupt Status Register. Once an interrupt event has occurred by exceeding TO , then reset, if the temperature remains above the THYST , the interrupt will not occur. (Figure 3-15 ) (3) One-Time Interrupt Mode Temperature exceeding TO causes an interrupt and then temperature going below THYST will not cause an interrupt. Once an interrupt event has occurred by exceeding TO , then going below THYST, an interrupt will not occur again until the temperature exceeding TO. (Figure 3-16 )

5.7 OVT# interrupt mode
The OVT# mode selection bits are at Bank0 Index18h bit4, Bank1 Index52h bit1 and Bank2 Index52h bit1. (1) Comparator Mode : Temperature exceeding TO causes the OVT# output activated until the temperature is less than THYST. ( Figure 3-19) (2) Interrupt Mode: Temperature exceeding TO causes the OVT# output activated indefinitely until reset by reading temperature sensor registers. Temperature exceeding TO, then OVT# reset, and then temperature going below THYST will also cause the OVT# activated indefinitely until reset by reading temperature sensor2 or sensor 3 registers. Once the OVT# is activated by exceeding TO , then reset, if the temperature remains above THYST , the OVT# will not be activated again.( Figure 3-19)

6. PLUG AND PLAY CONFIGURATION
The W83627THF uses Compatible PNP protocol to access configuration registers for setting up different types of configurations. In W83627THF, there are eleven Logical Devices (from Logical Device 0 to Logical Device B with the exception of logical device 4 for backward compatibility) which correspond to eleven individual functions: FDC (logical device 0), PRT (logical device 1), UART1 (logical device 2), UART2 (logical device 3), KBC (logical device 5), GPIO1,5 (logical device 7), GPIO2 (logical device 8), GPIO3,4 (logical device 9), ACPI ((logical device A), and hardware monitor (logical device B). Each Logical Device has its own configuration registers (above CR30). Host can access those registers by writing an appropriate logical device number into logical device select register at CR7.
6.1
Compatible PnP
6.1.1 Extended Function Registers In Compatible PnP, there are two ways to enter Extended Function and read or write the configuration registers. HEFRAS (CR26 bit 6) can be used to select one out of these two methods of entering the Extended Function mode as follows: HEFRAS 0 1 address and value write 87h to the location 2Eh twice write 87h to the location 4Eh twice
After Power-on reset, the value on RTSA# (pin 43) is latched by HEFRAS of CR26. In Compatible PnP, a specific value (87h) must be written twice to the Extended Functions Enable Register (I/O port address 2Eh or 4Eh). Secondly, an index value (02h, 07h-FFh) must be written to the Extended Functions Index Register (I/O port address 2Eh or 4Eh same as Extended Functions Enable Register) to identify which configuration register is to be accessed. The designer can then access the desired configuration register through the Extended Functions Data Register (I/O port address 2Fh or 4Fh). After programming of the configuration register is finished, an additional value (AAh) should be written to EFERs to exit the Extended Function mode to prevent unintentional access to those configuration Publication Release Date: May 21, 2003 Revision 0.7

W83627THF
registers. The designer can also set bit 5 of CR26 (LOCKREG) to high to protect the configuration registers against accidental accesses. The configuration registers can be reset to their default or hardware settings only by a cold reset (pin MR = 1). A warm reset will not affect the configuration registers. 6.1.2 Extended Functions Enable Registers (EFERs) After a power-on reset, the W83627THF enters the default operating mode. Before the W83627THF enters the extended function mode, a specific value must be programmed into the Extended Function Enable Register (EFER) so that the extended function register can be accessed. The Extended Function Enable Registers are write-only registers. On a PC/AT system, their port addresses are 2Eh or 4Eh (as described in previous section). Extended Function Index Registers (EFIRs), Extended Function Data Registers(EFDRs) After the extended function mode is entered, the Extended Function Index Register (EFIR) must be loaded with an index value (02h, 07h-FEh) to access Configuration Register 0 (CR0), Configuration Register 7 (CR07) to Configuration Register FE (CRFE), and so forth through the Extended Function Data Register (EFDR). The EFIRs are write-only registers with port address 2Eh or 4Eh (as described in section 12.2.1) on PC/AT systems, the EFDRs are read/write registers with port address 2Fh or 4Fh (as described in section 9.2.1) on PC/AT systems. 6.1.3
6.2
Configuration Sequence
To program W83627THF configuration registers, the following configuration sequence must be followed: (1). Enter the extended function mode (2). Configure the configuration registers (3). Exit the extended function mode 6.2.1 Enter the extended function mode To place the chip into the extended function mode, two successive writes of 0x87 must be applied to Extended Function Enable Registers(EFERs, i.e. 2Eh or 4Eh).

W83627THF
6.2.2 Configuration the configuration registers The chip selects the logical device and activates the desired logical devices through Extended Function Index Register(EFIR) and Extended Function Data Register(EFDR). EFIR is located at the same address as EFER, and EFDR is located at address (EFIR+1). First, write the Logical Device Number (i.e.,0x07) to the EFIR and then write the number of the desired logical device to the EFDR. If accessing the Chip(Global) Control Registers, this step is not required. Secondly, write the address of the desired configuration register within the logical device to the EFIR and then write (or read) the desired configuration register through EFDR. 6.2.3 Exit the extended function mode To exit the extended function mode, one write of 0xAA to EFER is required. Once the chip exits the extended function mode, it is in the normal running mode and is ready to enter the configuration mode. 6.2.4 Software programming example The following example is written in Intel 8086 assembly language. It assumes that the EFER is located at 2Eh, so EFIR is located at 2Eh and EFDR is located at 2Fh. If HEFRAS (CR26 bit 6) is set, 4Eh can be directly replaced by 4Eh and 2Fh replaced by 4Fh. ;----------------------------------------------------------------------------------; Enter the extended function mode ,interruptible double-write | ;----------------------------------------------------------------------------------MOV DX,2EH MOV AL,87H OUT DX,AL OUT DX,AL ;----------------------------------------------------------------------------; Configuration logical device 1, configuration register CRF0 | ;----------------------------------------------------------------------------MOV DX,2EH MOV AL,07H OUT DX,AL ; point to Logical Device Number Reg.
