GENERAL DESCRIPTION
This data sheet details the specific properties of the
PCF84C85A. The shared properties of the PCF84CxxxA
family of microcontrollers are described in the
“PCD84xxxA family”data sheet which should be read in
conjunction with this publication.
The PCF84C85A is a general purpose CMOS
microcontroller with emphasis on input/output. It provides
32 I/O port lines, 8 kbytes of program memory and
256 bytes of RAM. In addition to the 32 I/O port lines, the
microcontroller provides an on-chip I
2
C-bus interface. This
two-line serial bus extends the microcontroller's
capabilities when implemented with the powerful I
2
C-bus
peripherals.These include LCD drivers, telecom circuits,
AD/DA converters, clock/calendar circuits, EEPROM and
RAM and are listed in “Data Handbook IC12, I
2
C
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.
