Description

This data sheet details the specific properties of the PCF84C12A, PCF84C22A and PCF84C42A. The shared properties of the PCF84CxxxA PCF84C22A family of microcontrollers are described in the "PCF84CxxxA family" data sheet, which should be read in conjunction with this publication. Note that the devices described in PCF84C22A sheet do not feature I2C-bus compatibility or derivative logic, so the information given in the family data sheet about these features can be ignored.

The PCF84C12A, PCF84C22A and PCF84C42A are general purpose CMOS microcontrollers with 1 kbyte, 2 kbytes and 4 kbytes of program memory, respectively. They include 64 bytes of RAM and 13 I/O port lines. The instruction set of PCF84C22A is based on the MAB8048 and is a sub-set of that listed in the "PCF84CxxxA family" data sheet.
