CY7C264 - 8K x 8 Power-Switched and Reprogrammable PROM

Download the CY7C264 datasheet PDF. This datasheet also covers the CY7C263 variant, as both devices belong to the same 8k x 8 power-switched and reprogrammable prom family and are provided as variant models within a single manufacturer datasheet.

General Description

The CY7C261, CY7C263, and CY7C264 are high-performance 8192-word by 8-bit CMOS PROMs.

the CY7C261 automatically powers down into a low-power standby mode.

It is packaged in a 300-mil-wide package.
