CMOS Programmable Peripheral Interface
The Intersil 82C55A is a high performance
CMOS version of the industry standard 8255A and is manufactured using a self-aligned silicon gate
CMOS process (Scaled SAJI IV).
The MX82C55A has identical features as the X82C55 with the exception of no bus hold devices on the port pins.
It is a general purpose programmable I/O device which may be used with many different microprocessors.
There are 24 I/O pins which may be individually programmed in two groups of 12 and used in three major modes of operation.
The high performance and industry standard configuration of the 82C...
