Description
The HS-81C55/56RH are radiation hardened RAM and I/O
chips 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-81C55/56RH is intended for use with the
HS-80C85RH radiation hardened microprocessor system. The
RAM portion is designed as 2048 static cells organized as 256
x 8. A maximum post irradiation access time of 500ns allows
the HS-81C55/56RH to be used with the HS-80C85RH CPU
without any wait states. The HS-81C55RH requires an active
low chip enable while the HS-81C56RH requires an active high
chip enable. These chips are designed for operation utilizing a
single 5V power supply.
