3 / 20 page 1996 Nov 20 3 Philips Semiconductors Product specification Telecom microcontrollers PCF84C21A; PCF84C41A; PCF84C81A 1 FEATURES • Manufactured in silicon gate CMOS process • 8-bit CPU, ROM, RAM, I/O in a 28-lead package • 2 kbyte ROM, 64 byte RAM (PCF84C21A) • 4 kbyte ROM, 128 byte RAM (PCF84C41A) • 8 kbyte ROM, 256 byte RAM (PCF84C81A) • I2C-bus interface with multi-master capability • Over 100 instructions (based on MAB8048) all of 1 or 2 cycles • 20 quasi-bidirectional I/O Port lines • High sink current capability on the 8 lines of Port 1 • 8-bit programmable timer/event counter 1 • 3 single-level vectored interrupts: – external – 8-bit programmable timer/event counter 1 –I2C-bus • Two test inputs, one of which also serves as the external interrupt input • Stop and Idle modes • Supply voltage: 2.5 to 5.5 V • Clock frequency: 1 to 16 MHz • Operating temperature: −40 to +85 °C. 2 GENERAL DESCRIPTION This data sheet details the specific properties of the PCF84C21A, PCF84C41A and PCF84C81A. 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 PCF84C21A, PCF84C41A and PCF84C81A are general purpose CMOS microcontrollers with 2 kbytes, 4 kbytes and 8 kbytes of program memory and 64,128 and 256 bytes of RAM, respectively. In addition to 20 I/O port lines, the microcontrollers provide an on-chip I2C-bus interface. This two-line serial bus extends the microcontroller capabilities when implemented with the powerful I2C-bus peripherals. These include LCD drivers, I/O expanders, telecom circuits, ADC and DAC converters, clock/calendar circuits, EEPROM and RAM and are listed in “Data Handbook IC12, I2C Peripherals”. The instruction set is based on that of the MAB8048 and is a sub-set of that listed in the “PCF84CxxxA family” data sheet. 3 ORDERING INFORMATION (see note 1) Note 1.
