22C10 - 256-BitNonvolatileCMOSStaticRAM

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).

Features

  • s Single 5V Supply s Fast RAM Access Times: s Low CMOS Power Consumption:.
  • 200ns.
  • 300ns s Infinite E PROM to RAM Recall s CMOS and TTL Compatible I/O s Power Up/Down Protection s 100,000 Program/Erase Cycles (E2PROM) 2.
  • Active: 40mA Max.
  • Standby: 30 µA Max. s JEDEC Standard Pinouts:.
  • 18-pin DIP.
  • 16-pin SOIC s 10 Year Data Retention s Commercial, Industrial and Automotive Temperature Ranges.
