CY7C266 - 8Kx8 Power-Switched and Reprogrammable PROM

General Description

The CY7C266 is a high-performance 8192-word by 8-bit CMOS PROM.

Key Features

  • CMOS for optimum speed/power.
  • Windowed for reprogrammability.
  • High speed.
  • 20 ns (Commercial).
  • Low power.
  • 660 mW (Commercial).
  • Super low standby power.
  • Less than 85 mW when deselected.
  • EPROM technology 100% programmable.
  • 5V ±10% VCC, commercial and military.
  • TTL-compatible I/O.
  • Direct replacement for 27C64 EPROMs powers down into a low-power standby mode. It is packaged in a 600-mil-wide p.

1CY7C266 CY7C266 8Kx8 Power-Switched and Reprogrammable PROM Features • CMOS for optimum speed/power • Windowed for reprogrammability • High speed — 20 ns (Commercial) • Low power — 660 mW (Commercial) • Super low standby power — Less than 85 mW when deselected • EPROM technology 100% programmable • 5V ±10% VCC, commercial and military • TTL-compatible I/O • Direct replacement for 27C64 EPROMs powers down into a low-power standby mode. It is packaged in a 600-mil-wide package. The reprogrammable packages are equipped with an erasure window; when exposed to UV light, these PROMs are erased and can then be reprogrammed. The memory cells utilize proven EPROM floating-gate technology and byte-wide intelligent programming algorithms. The CY7C266 is a plug-in replacement for EPROM devices.
