10µA WS82C55A Description The WS82C55A 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).
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 2 groups of 12 and used in 3 major modes of operation.
The high performance and industry standard configuration of the WS82C55A make it compatible with the 80C86, and other microprocessors.
Static CMOS circuit design insures low operating power.
