Radiation Hardened 256 x 8 CMOS RAM  
Features  
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.  
• Electrically Screened to SMD # 5962-96766  
• QML Qualified per MIL-PRF-38535 Requirements  
• Radiation Hardened EPI-CMOS

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.  
• Electrically Equivalent to Sandia SA 3001  
• Pin Compatible with Intel 8155/56  
• Bus Compatible with HS-80C85RH  
• Single 5V Power Supply  
• Low Standby Current . . . . . . . . . . . . . . . . . . . .200µA Max  
• Low Operating Current . . . . . . . . . . . . . . . . . . . . 2mA/MHz  
• Completely Static Design  
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.  
• Internal Address Latches  
Two Programmable 8-Bit I/O Ports  
• One Programmable 6-Bit I/O Port  
Detailed Electrical Specifications for these devices are
