The 87C196LA is composed of a high-speed core with the following peripherals: an asynchronous/synchronous serial I/O port (8096 compatible) with a dedicated 16-bit baud-rate generator; an additional synchronous serial I/O port with full duplex master/slave transceivers; a six-channel A/D converter with sample and hold; a flexible timer/counter structure with prescaler, cascading, and quadrature capabilities; six modularized, multiplexed high-speed I/O for capture and compare (called event processor array) with 200 ns resolution and double buffered inputs; and a sophisticated, prioritized interrupt structure with programmable peripheral transaction server (PTS). The clock doubler circuitry and oscillator output signal enable a 4 MHz resonator to achieve the same internal clock speed as a more costly 8 MHz resonator in previous applications. This same circuitry can drive other devices where a separate resonator was required in the past. Another cost-savings feature is the fact that the I/O ports are driven low at reset, avoiding the need for pull-up resistors.

Signal Descriptions (Sheet 1 of 6) Name Type Analog Channels These signals are analog inputs to the A/D converter. The A/D inputs share package pins with port 0. These pins may individually be used as analog inputs (ACHx) or digital inputs (P0.y). While it is possible for the pins to function simultaneously as analog and digital inputs, this is not recommended because reading port 0 while a conversion is in process can produce unreliable conversion results. The ANGND and VREF pins must be connected for the A/D converter and port 0 to function. ACH7:2 share package pins with the following signals: ACH2/P0.2, ACH3/P0.3, ACH4/P0.4/PMODE.0, ACH5/P0.5/PMODE.1, ACH6/P0.6/PMODE.2, and ACH7/ P0.7/PMODE.3. Address/Data Lines These pins provide a multiplexed address and data bus. During the address phase of the bus cycle, address bits 0-15 are presented on the bus and can be latched using ALE or ADV#. During the data phase, 8- or 16-bit data is transferred. AD7:0 share package pins with P3.7:0 and PBUS.7:0. AD15:8 share package pins with P4.7:0 and PBUS.15:8. Address Valid This active-low output signal is asserted only during external memory accesses. ADV# indicates that valid address information is available on the system address/ data bus. The signal remains low while a valid bus cycle is in progress and is returned high as soon as the bus cycle completes. An external latch can use this signal to demultiplex the address from the address/ data bus. A decoder can also use this signal to generate chip selects for external memory. ADV# shares a package pin with P5.0 and ALE. Auto Increment During slave programming, this active-low input enables the auto-increment feature. (Auto increment allows reading or writing of sequential OTPROM locations, without requiring address transactions across the programming bus for each read or write.) AINC# is sampled after each location is programmed or dumped. If AINC# is asserted, the address is incremented and the next data word is programmed or dumped. AINC# shares a package pin with P2.4. Description ACH7:2 I AD15:0 I/O ADV# O AINC# I Advance Information Datasheet 11 87C196LA-20 MHz CHMOS 16-bit Microcontroller -- Automotive Table 4. Signal Descriptions (Sheet 2 of 6) Name Type Address Latch Enable This active-high output signal is asserted only during external memory cycles. ALE signals the start of an external bus cycle and indicates that valid address information is available on the system address/data bus. An external latch can use this signal to demultiplex the address from the address/ data bus. ALE shares a package pin with P5.0 and ADV#. Analog Ground ANGND GND ANGND must be connected for A/D converter and port 0 operation. ANGND and VSS should be nominally at the same potential. Clock Output CLKOUT O Output of the internal clock generator. You can select one of three frequencies: f, f/2, or f/4. CLKOUT has a 50% duty cycle. CLKOUT shares a package pin with P2.7 and PACT#. Event Processor Array (EPA) Compare Pins COMP1:0 O These signals are the outputs of the EPA compare-only channels. COMP1:0 share package pins with the following signals: COMP0/P6.0/EPA8 and COMP1/P6.1/EPA9. Cumulative Program Verification CPVER O During slave or programming, a high signal indicates that all locations programmed correctly, while a low signal indicates that an error occurred during the program operation. CPVER shares a package pin with P2.6 and ONCE#. External Access This input determines whether memory accesses to special-purpose and program memory partitions are directed to internal or external memory. These accesses are directed to internal memory if EA# is held high and to external memory if EA# is held low. For an access to any other memory location, the value of EA# is irrelevant. EA# also controls entry into the programming modes. If EA# is at VPP voltage (typically +12.5 V) on the rising edge of RESET#, the microcontroller enters a programming mode. EA# is sampled and latched only on the rising edge of RESET#. Changing the level of EA# after reset has no effect. Event Processor Array (EPA) Capture/Compare Channels High-speed input/output signals for the EPA capture/compare channels. EPA9:8 EPA3:0 I/O The EPA signals share package pins with the following signals: EPA0/P1.0/T2CLK, EPA1/P1.1, EPA2/P1.2/T2DIR, EPA3/P1.3, EPA8/P6.0/COMP0, and EPA9/P6.1/ COMP1. EPA7:6 do not connect to package pins. They cannot be used to capture an event, but they can function as software timers. EPA5:4 are not implemented. Description ALE O EA# I 12 Advance Information Datasheet Automotive -- 87C196LA-20 MHz CHMOS 16-bit Microcontroller Table 4. Signal Descriptions (Sheet 3 of 6) Name Type External Interrupt In normal operating mode, a rising edge on EXTINT sets the EXTINT interrupt pending bit. EXTINT is sampled during phase 2. The minimum high time is one state time. EXTINT I In powerdown mode, asserting the EXTINT signal causes the device to resume normal operation. The interrupt does not need to be enabled. In idle mode, asserting any enabled interrupt causes the device to resume normal operation. EXTINT shares a package pin with P2.2 and PROG#. Port 0 This is a high-impedance, input-only port. Port 0 pins should not be left floating. The port 0 signals share package pins with the A/D inputs. These pins may individually be used as analog inputs (ACHx) or digital inputs (P0.y). While it is possible for the pins to function simultaneously as analog and digital inputs, this is not recommended because reading port 0 while a conversion is in process can produce unreliable conversion results. ANGND and VREF must be connected for port 0 to function. P0.3:2 share package pins with ACH3:2 and P0.7:4 share package pins with ACH7:4 and PMODE.3:0. Port 1 P1.3:0 I/O This is a standard bidirectional port that shares package pins with individually selectable special-function signals. Port 1 shares package pins with the following signals: P1.0/EPA0/T2CLK, P1.1/ EPA1, P1.2/EPA2/T2DIR, P1.3/EPA3. Port 2 P2.7:6 P2.4 P2.2:0 I/O This is a standard bidirectional port that shares package pins with individually selectable special-function signals. Port 2 shares package pins with the following signals: P2.0/TXD/PVER, P2.1/RXD/ PALE#, P2.2/EXTINT/PROG#, P2.4/AINC#, P2.6/ONCE/CPVER. P2.7/OSCOUT/PACT# is output pin only. Port 3 P3.7:0 I/O This is a memory-mapped, 8-bit, bidirectional port with programmable open-drain or complementary output modes. The pins are shared with the multiplexed address/data bus, which has complementary drivers. P3.7:0 share package pins with AD7:0 and PBUS.7:0. Port 4 P4.7:0 I/O This is a memory-mapped, 8-bit, bidirectional port with open-drain or complementary output modes. The pins are shared with the multiplexed address/ data bus, which has complementary drivers. P4.7:0 share package pins with AD15:8 and PBUS.15:8. Port 5 P5.3:2 P5.0 I/O This is a memory-mapped, bidirectional port. Port 5 shares package pins with the following signals: P5.0/ADV#/ALE, P5.2/WR#/ WRL#/PLLEN, and P5.3/RD#. P5.1 and P5.7:4 are not implemented. Description P0.7:2 I Advance Information Datasheet 13 87C196LA-20 MHz CHMOS 16-bit Microcontroller -- Automotive Table 4. Signal Descriptions (Sheet 4 of 6) Name P6.7:4 P6.1:0 Type Port 6 O This is a standard bidirectional port. Port 6 shares package pins with the following signals: P6.0/EPA8/COMP0, P6.1/ EPA9/COMP1, P6.4/SC0, P6.5/SD0, P6.6/SC1, and P6.7/SD1. Programming Active PACT# O During auto programming or slave dump, a low signal indicates that programming or dumping is in progress, while a high signal indicates that the operation is complete. PACT# shares a package pin with P2.7 and OSCOUT. Programming ALE PALE# I During slave programming, a falling edge causes the device to read a command and address from the programming bus. PALE# is multiplexed with P2.1 and RXD. Address/Command/Data Bus During slave programming, ports 3 and 4 serve as a bidirectional port with opendrain outputs to pass commands, addresses, and data to or from the device. Slave programming requires external pull-up resistors. During auto programming and ROM-dump, ports 3 and 4 serve as a regular system bus to access external memory. P4.6 and P4.7 are left unconnected; P1.1 and P1.2 serve as the upper address lines. Slave programming: PBUS.7:0 share package pins with AD7:0 and P3.7:0. PBUS.15:8 share package pins with AD15:8 and P4.7:0. Auto programming: PBUS.15:8 share package pins with AD15:8 and P4.7:0; PBUS.7:0 share package pins with AD7:0 and P3.7:0. Phase-locked Loop Enable PLLEN I This active-high input pin enables the on-chip clock multiplier. Tie this pin to VCC at power-up to bypass the on-chip clock multiplier. Programming Mode Select PMODE.3:0 I These pins determine the programming mode. PMODE3:0 are sampled after a device reset and must be static while the microcontroller is operating. PMODE3:0 share package pins with P0.7:4 and ACH7:4. Programming Start During programming, a falling edge latches data on the programming bus and begins programming, while a rising edge ends programming. The current location is programmed with the same data as long as PROG# remains asserted, so the data on the programming bus must remain stable while PROG# is active. During a word dump, a falling edge causes the contents of an OTPROM location to be output on the PBUS, while a rising edge ends the data transfer. PROG# shares a package pin with P2.2 and EXTINT. Program Verification PVER O During slave or auto programming, PVER is updated after each programming pulse. A high output signal indicates successful programming of a location, while a low signal indicates a detected error. PVER shares a package pin with P2.0 and TXD. Description PBUS.15:0 I/O PROG# I 14 Advance Information Datasheet Automotive -- 87C196LA-20 MHz CHMOS 16-bit Microcontroller Table 4. Signal Descriptions (Sheet 5 of 6) Name Type Read RD# O Read-signal output to external memory. RD# is asserted during external memory reads. RD# shares a package pin with P5.3. Reset A level-sensitive reset input to, and an open-drain system reset output from, the microcontroller. Either a falling edge on RESET# or an internal reset turns on a pull-down transistor connected to the RESET# pin for 16 state times. In the powerdown and idle modes, asserting RESET# causes the microcontroller to reset and return to normal operating mode. After a reset, the first instruction fetch is from 2080H. Receive Serial Data RXD I/O In modes 1, 2, and 3, RXD receives serial port input data. In mode 0, it functions as either an input or an open-drain output for data. RXD shares a package pin with P2.1 and PALE#. Clock Pins for SSIO0 and 1 For handshaking transfers, configure SC1:0 as open-drain outputs. SC1:0 I/O This pin carries a signal only during receptions and transmissions. When the SSIO port is idle, the pin remains either high (with handshaking) or low (without handshaking). SC0 shares a package pin with P6.4, and SC1 shares a package pin with P6.6. Data Pins for SSIO0 and 1 SD1:0 I/O These pins are the data I/O pins for SSIO0 and 1. For transmissions, configure SDx as a complementary output signal. For receptions, configure SDx as a highimpedance input signal. SD0 shares a package pin with P6.5, and SD1 shares a package pin with P6.7. Timer 2 External Clock T2CLK I External clock for timer 2. Timer 2 increments (or decrements) on both rising and falling edges of T2CLK. It is also used in conjunction with T2DIR for quadrature counting mode. T2CLK shares a package pin with P1.0 and EPA0. Timer 2 External Direction T2DIR I External direction (up/down) for timer 2. Timer 2 increments when T2DIR is high and decrements when it is low. It is also used in conjunction with T2CLK for quadrature counting mode. T2DIR shares a package pin with P1.2 and EPA2. Transmit Serial Data TXD O In serial I/O modes 1, 2, and 3, TXD transmits serial port output data. In mode 0, it is the serial clock output. TXD shares a package pin with P2.0 and PVER. Description RESET# I/O Advance Information Datasheet 15 87C196LA-20 MHz CHMOS 16-bit Microcontroller -- Automotive Table 4. Signal Descriptions (Sheet 6 of 6) Name VCC Type Digital Supply Voltage PWR Connect each VCC pin to the digital supply voltage. Programming Voltage VPP PWR VPP causes the device to exit powerdown mode when it is driven low for at least 50 ns. Use this method to exit powerdown only when using an external clock source because it enables the internal phase clocks, but not the internal oscillator. If you do not plan to use the powerdown feature, connect VPP to VCC. Reference Voltage for the A/D Converter VREF PWR This pin supplies operating voltage to the A/D converter. Digital Circuit Ground VSS, VSS1 GND These pins supply ground for the digital circuitry. Connect each VSS and VSS1 pin to ground through the lowest possible impedance path. VSS pins are connected to the core ground region of the microcontroller, while VSS1 pins are connected to the port ground region. (ANGND is connected to the analog ground region.) Separating the ground regions provides noise isolation. Write This active-low output indicates that an external write is occurring. This signal is asserted only during external memory writes. Forcing WR# high while RESET# is low causes the device to enter PLL-bypass mode. When the device is in PLL-bypass mode, the internal phase clocks operate at one-half the frequency of the frequency on XTAL1. WR# shares a package pin with P5.2, WRL#, and PLLEN. When Description WR# O this pin is configured as a special-function signal (P5_MODE.2 = 1), the chip configuration register 0 (CCR0) determines whether it functions as WR# or WRL#. CCR0.2 = 1 selects WR#; CCR0.2 = 0 selects WRL#. Write Low During 16-bit bus cycles, this active-low output signal is asserted for low-byte writes and word writes to external memory. During 8-bit bus cycles, WRL# is asserted for all write operations. WRL# O WRL# shares a package pin with P5.2, WR#, and PLLEN. When this pin is configured as a special-function signal (P5_MODE.2 = 1), the chip configuration register 0 (CCR0) determines whether it functions as WR# or WRL#. CCR0.2 = 1 selects WR#; CCR0.2 = 0 selects WRL#. Input Crystal/Resonator or External Clock Input XTAL1 I Input to the on-chip oscillator and the internal clock generators. The internal clock generators provide the peripheral clocks, CPU clock, and CLKOUT signal. When using an external clock source instead of the on-chip oscillator, connect the clock input to XTAL1. The external clock signal must meet the VIH specification for XTAL1. Inverted Output for the Crystal/Resonator XTAL2 O Output of the on-chip oscillator inverter. Leave XTAL2 floating when the design uses an external clock source instead of the on-chip oscillator. 16 Advance Information Datasheet Automotive -- 87C196LA-20 MHz CHMOS 16-bit Microcontroller 5.0 Address Map Table 5.

The AD_TIME register only programs the speed at which the conversions are performed, not the speed at which it can convert correctly. The converter is ratiometric, so absolute accuracy is dependent on the accuracy and stability of VREF. VREF must be within 0.5 V of VCC since it supplies both the resistor ladder and the digital portion of the converter and input port pins. For testing purposes, after a conversion is started, the device is placed in the IDLE mode until the conversion is complete. Testing is performed at VREF = 5.12 V and 20 MHz operating frequency. There is an AD_TEST register that allows for conversion on ANGND and VREF, as well as zero offset adjustment. The absolute error listed is without doing any adjustments.
