CAT28C257 Datasheet 256k-bit CMOS Parallel E2prom

Manufacturer: Catalyst Semiconductor

Overview: Advanced CAT28C257 256K-Bit CMOS PARALLEL E2PROM.

General Description

The CAT28C257 is a fast, low power, 5V-only CMOS Parallel E2PROM organized as 32K x 8-bits.

It requires a simple interface for in-system programming.

On-chip address and data latches, self-timed write cycle with autoclear and VCC power up/down write protection eliminate additional timing and protection hardware.
