Description
The Intersil HS-82C55ARH is a high performance, radiation hardened
CMOS version of the industry standard 8255A and is manufactured using a
hardened 鏗乪ld, self-aligned silicongate CMOS process. It is a general
purpose programmable I/O device which may be used with many different
microprocessors. There are 24 I/O pins which are organized into two 8-bit
and two 4-bit ports. Each port may be programmed to function as either an
input or an output. Additionally, one of the 8-bit ports may be programmed
for bi-directional operation,and the two 4-bit ports can be programmed to
provide handshaking capabilities. The high performance, radiation
hardness, and industry standard con鏗乬uration of the HS-82C55ARH make
it compatible with the HS-80C86RH radiation hardened microprocessor.
Static CMOS circuit design insures low operating power. Bus hold circuitry
eliminates the need for pull-up resistors. The Intersil hardened 鏗乪ld CMOS
process results in performance equal to or greater than existing radiation
resistant products at a fraction of the power.
