24C44 - 256-Bit Serial Nonvolatile CMOS Static RAM

Datasheet Summary

Description

The CAT24C44 Serial NVRAM is a 256-bit nonvolatile memory organized as 16 words x 16 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 Infinite E2PROM to RAM Recall s CMOS and TTL Compatible I/O s Low CMOS Power Consumption: s JEDEC Standard Pinouts:.
  • 8-pin DIP.
  • 8-pin SOIC s 100,000 Program/Erase Cycles (E2PROM) s Auto Recall on Power-up s Commercial, Industrial and Automotive.
  • Active: 3 mA Max.
  • Standby: 30 µA Max. s Power Up/Down Protection s 10 Year Data Retention Temperature Ranges.
