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 of PCF84C41A provide an on-chip I2C-bus interface. This two-line serial bus PCF84C41A 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.
