Product Summary
The CY7C271-55WMB is a high-performance 32,768-word by 8-bit CMOS PROM. When disabled (CE HIGH), the CY7C271-55WMB automatically powers down into a low-power stand-by mode. The CY7C271-55WMB is packaged in the 300-mil slim package. Both the CY7C271-55WMB is an 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 algorithm.
