CY62256 - 256K (32K x 8) Static RAM

Download the CY62256 datasheet PDF. This datasheet also covers the CY6 variant, as both devices belong to the same 256k (32k x 8) static ram family and are provided as variant models within a single manufacturer datasheet.

General Description

The CY62256 is a high-performance CMOS static RAM organized as 32K words by 8 bits.

Easy memory expansion is provided by an active LOW chip enable (CE) and active LOW output enable (OE) and three-state drivers.

This device has an automatic power-down feature, reducing the power consumption by 99.

Key Features

  • High speed: 55 ns and 70 ns.
  • Voltage range: 4.5V.
  • 5.5V operation.
  • Low active power (70 ns, LL version).
  • 275 mW (max. ).
  • Low standby power (70 ns, LL version).
  • 28 µW (max. ).
  • Easy memory expansion with CE and OE features.
  • TTL-compatible inputs and outputs.
  • Automatic power-down when deselected.
  • CMOS for optimum speed/power.
  • Package available in a standard 450-mil-wide (300-mil body width) 28-le.
