Description
The HS-83C55RH is a radiation hardened ROM and I/O chip fabricated
using the Intersil radiation hardened Self-Aligned Junction Isolated
(SAJI) silicon gate technology. Latch-up free operation is achieved by
the use of epitaxial starting material to eliminate the parasitic SCR effect
seen in conventional bulk CMOS devices.
The HS-83C55RH is intended for use with the HS-80C85RH radiation
hardened microprocessor system.
The ROM portion is designed as 16,384 mask programmable cells orga-
nized in a 2048 word x 8-bit format. A maximum post irradiation access
time of 340ns allows the HS-83C55RH to be used with the HS-80C85RH
CPU without any wait states. This ROM is designed for operation utilizing
a single 5 volt power supply.
