INTRODUCTION
The UT7C138 and UT7C139 are high-speed radiationhardened CMOS 4K x 8 and 4K x 9 dual-port static RAMs. Arbitration schemes are included on the UT7C138/139 to handle situations when multiple processors access the same memory location. Two ports provide independent, asynchronous access for reads and writes to any location in memory.
FEATURES
? 45ns and 55ns maximum address access time
? Asynchronous operation for compatibility with industry
standard 4K x 8/9 dual-port static RAM
? CMOS compatible inputs, TTL/CMOS compatible output
levels
? Three-state bidirectional data bus
? Low operating and standby current
? Radiation-hardened process and design; total dose
irradiation testing to MIL-STD-883 Method 1019
- Total-dose: 1.0E6 rads(Si)
- Memory Cell LET threshold: 85 MeV-cm2/mg
- Latchup immune (LET >100 MeV-cm2/mg)
? QML Q and QML V compliant part
? Packaging options:
- 68-lead Flatpack
- 68-pin PGA
? 5-volt operation
? Standard Microcircuit Drawing 5962-96845
