unctional Descriptio
The CY7C271A is a high-performance 32,768-word by 8-bit CMOS PROM. When disabled (CE HIGH), the 7C271A automatically powers down into a low-power stand-by mode. The CY7C271A is packaged in the 300-mil slim package and is 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.
