Radiation Hardened CMOS Programmable
Peripheral Interface
The Intersil HS-82C55ARH is a high performance, radiation
hardened CMOS version of the industry standard 8255A and
is manufactured using a hardened field, self-aligned silicon
gate 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
bidirectional operation, and the two 4-bit ports can be
programmed to provide handshaking capabilities. The high
performance, radiation hardness, and industry standard
configuration 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 field CMOS process results in performance
equal to or greater than existing radiation resistant products
at a fraction of the power.
Specifications for Rad Hard QML devices are controlled
by the Defense Supply Center in Columbus (DSCC). The
SMD numbers listed here must be used when ordering.
Detailed Electrical Specifications for these devices are
contained in SMD 5962-95819. A “hot-link” is provided
