DESCRIPTION
The CAT22C10 NVRAM is a 256-bit nonvolatile memory organized as 64 words x 4 bits. The high speed Static RAM array is bit for bit backed up by a nonvolatile E2PROM array which allows for easy transfer of data from RAM array to E2PROM (STORE) and from E2PROM to RAM (RECALL). STORE operations are completed in 10ms max. and RECALL operations typically within 1.5µs.

FEATURES
■ Single 5V Supply
■ Fast RAM Access Times:
  –200ns
  –300ns
■ Infinite E2PROM to RAM Recall
■ CMOS and TTL Compatible I/O
■ Power Up/Down Protection
■ 100,000 Program/Erase Cycles (E2PROM)
■ Low CMOS Power Consumption:
  –Active: 40mA Max.
  –Standby: 30 µA Max.
■ JEDEC Standard Pinouts:
  –18-pin DIP
  –16-pin SOIC
■ 10 Year Data Retention
■ Commercial, Industrial and Automotive Temperature Ranges
