This data sheet details the specific properties of the
PCF84C12A, PCF84C22A and PCF84C42A. 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.
Note that the devices described in this data sheet do not
feature I
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 is based on the MAB8048 and is a
sub-set of that listed in the “PCF84CxxxA family” data
sheet.
