Description
The HS-80C85RH is an 8-bit CMOS microprocessor fabri-
cated using the Intersil radiation hardened self-aligned junc-
tion 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-80C85RH is a functional logic emulation of the
HMOS 8085 and its instruction set is 100% software com-
patible with the HMOS device. The HS80C85RH is designed
for operation with a single 5 volt power supply. Its high level
of integration allows the construction of a radiation hardened
microcomputer system with as few as three ICs (HS-
80C85RH CPU, HS83C55RH ROM I/O, and the HS-81C55/
56RH RAM I/O.
