CY7C274-45JC

32K ×8电源开关和可重复编程的PROM 32K x 8 Power Switched and Reprogrammable PROM

Functional Description

The CY7C271 and CY7C274 are high-performance 32,768-word by 8-bit CMOS PROMs. When disabled CE HIGH, the 7C271/7C274 automatically powers down into alow-power stand-by mode. The CY7C271 is packaged in the 300-mil slim package. The CY7C274 is packaged in the industry standard 600-mil package. Both the CY7C271 and CY7C274 are available in a cerDIP package equipped with an erasure window to provide for reprogrammability. When exposed to UV light, the PROM is erased and can be reprogrammed. The memory cells utilize proven EPROM floating gate technology and byte-wide intelligent programming algorithms.
