HS-82C55ARH TM Data Sheet August 2000 File Number 3191.2 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.
