... Functional Description The CY7C277 is a high-performance 32K word by 8-bit CMOS PROMs packaged in the slim 28-pin 300-mil package. The ceramic package may be equipped with an erasure window; when exposed to UV light, the PROM is erased and can then be reprogrammed. The memory cells utilize proven EPROM floating-gate technology and byte-wide algorithms ...
