CY7C291A - 2K x 8 Reprogrammable PROM

Description

The CY7C291A is a high-performance 2K-word by 8-bit CMOS PROM.

It is packaged in a 300-mil ceramic package which may be equipped with an erasure window; when exposed to UV light the PROM is erased and can then be reprogrammed.

Features

  • Windowed for reprogrammability.
  • CMOS for optimum speed/power.
  • High speed.
  • 20 ns (Commercial).
  • 35 ns (Military).
  • Low power.
  • 660 mW (Commercial and Military).
  • Low standby power.
  • 220 mW (Commercial and Military).
  • EPROM technology 100% programmable.
  • Slim 300-mil or standard 600-mil packaging available.
  • 5V ±10% VCC, commercial and military.
  • TTL-compatible I/O.
  • Direct replacem.
