This data sheet details the specific properties of the PCF84C00. The shared properties of the PCF84CxxxA family of microcontrollers are described in the "PCF84CxxxA family" data sheet, which should be read in conjunction with this publication. The PCF84C00 has 20 quasi-bidirectional I/O lines, an I2C-bus serial interface, a single-level vectored interrupt structure, an 8-bit timer/event counter and on-chip clock oscillator and clock circuits. This efficient controller also performs well as an arithmetic processor. It has facilities for both binary and BCD arithmetic plus bit-handling capabilities. The instruction set is similar to the MAB8048 and is a sub-set of that listed in the "PCF84CxxxA family" data sheet.
PACKAGE NAME - DESCRIPTION Non-standard 28-lead `piggy-back' package with 28-pin EPROM socket on top. Bottom `footprint' and pinning as DIP 28, version SOT117-1. The SOT117-1 information provided in Chapter "Package Outlines" is correct in these respects, but not for the physical size of the PCF84C00B, which is larger than the SOT117-1 package. Plastic very small outline package; 56 leads. VERSION -

6 6.1 FUNCTIONAL DESCRIPTION `Piggy-back' version PCF84C00B
PCF84C00
* INT/T0; External interrupt and test input. When used as a test input, it can be directly tested by conditional branch instructions JT0 and JNT0. * T1; Test input which can alter program sequences when tested by conditional jump instructions JT1 and JNT1. T1 also functions as an input to the 8-bit timer/event counter. 6.5 Reset
The PCF84C00B package has standard pinning on the bottom to facilitate insertion as a mask-programmed device. An EPROM can be mounted on top in an additional socket. The total package height is greater than the height of a standard DIP package. The PCF84C00B can address up to 8 kbytes of external ROM/RAM, and has 256 bytes of internal data RAM. 6.2 ROM-less version PCF84C00T
A positive-going signal on the RESET input/output: * Sets the program counter to zero * Selects location 0 of memory bank 0 and register bank 0 * Sets the stack pointer to zero (000); pointing to RAM address 8 * Disables the interrupts (external, timer and I2C-bus) * Stops the timer/event counter, then sets it to zero * Sets the timer prescaler to divide by 32 * Resets the timer flag * Sets all ports except P2.3 to input mode * Sets the I2C-bus interface to slave receiver mode and disables the I2C-bus interface * Cancels Idle and Stop mode. A negative-going signal on the RESET input/output: * Sets P2.3/SDA and SCLK to HIGH after a maximum of 30 clock pulses * Sets the I2C-bus interface to slave receiver mode and disables the I2C-bus interface after a maximum of 30 clock pulses * Starts program execution after 1866 clock pulses.
The PCF84C00T microcontroller contains no on-chip ROM, but has all address and data lines brought out to access an external ROM or EPROM. Consequently, this version has more pins (see Fig.5) than the devices in the PCF84CxxxA family with on-chip or `piggy-back' ROM. The PCF84C00T can address up to 8 kbytes of external program memory, and has 256 bytes of internal data RAM. 6.3 Data memory
Data memory consists of 256 bytes of Random-Access Memory (RAM). All locations are indirectly addressable using RAM pointer registers; up to 16 designated locations are directly addressable. Memory also includes an 8-level program counter stack addressed by a 3-bit stack pointer. 6.4 I/O facilities
Each device has 23 I/O lines arranged as follows: * Port 0; 8-bit parallel port (P0.0-P0.7) * Port1; 8-bit parallel port (P1.0-P1.7) * Port 2; 4-bit parallel port (P2.0-P2.3) * SCLK ; I2C-bus (serial I/O) clock line

12 SOLDERING 12.1 Introduction
PCF84C00
There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "IC Package Databook" (order code 9398 652 90011). 12.2 12.2.1 DIP SOLDERING BY DIPPING OR BY WAVE
Several techniques exist for reflowing; for example, thermal conduction by heated belt. Dwell times vary between 50 and 300 seconds depending on heating method. Typical reflow temperatures range from 215 to 250 C. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 C. 12.3.2 WAVE SOLDERING
Wave soldering techniques can be used for all SO and VSO packages if the following conditions are observed: * A double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. * The longitudinal axis of the package footprint must be parallel to the solder flow. * The package footprint must incorporate solder thieves at the downstream end. During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Maximum permissible solder temperature is 260 C, and maximum duration of package immersion in solder is 10 seconds, if cooled to less than 150 C within 6 seconds. Typical dwell time is 4 seconds at 250 C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 12.3.3 REPAIRING SOLDERED JOINTS
The maximum permissible temperature of the solder is 260 C; solder at this temperature must not be in contact with the joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg max). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. 12.2.2 REPAIRING SOLDERED JOINTS
Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 C, contact may be up to 5 seconds. 12.3 12.3.1 SO and VSO REFLOW SOLDERING
Reflow soldering techniques are suitable for all SO and VSO packages. Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement.
Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron (less than 24 V) applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 C.

PCF84C00
This data sheet contains target or goal specifications for product development. This data sheet contains preliminary data; supplementary data may be published later. This data sheet contains final product specifications.
Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability. Application information Where application information is given, it is advisory and does not form part of the specification. 14 LIFE SUPPORT APPLICATIONS These products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be expected to result in personal injury. Philips customers using or selling these products for use in such applications do so at their own risk and agree to fully indemnify Philips for any damages resulting from such improper use or sale. 15 PURCHASE OF PHILIPS I2C COMPONENTS
Purchase of Philips I2C components conveys a license under the Philips' I2C patent to use the components in the I2C system provided the system conforms to the I2C specification defined by Philips. This specification can be ordered using the code 9398 393 40011.
