NAME
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.

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
I
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.
