Description

The CY7C264-45WC is a CMOS PROM chip that belongs to the CY7C series. It is a high-performance 8192-word by 8-bit PROM that features byte-wide intelligent programming algorithms and proven EPROM floating-gate technology. It is capable of withstanding greater than 2001V static discharge. The reprogrammable package has a window for UV light exposure, which will erase the PROM and allow it to be reprogrammed. The CY7C264-45WC is available in a 600-mil-wide package, delivering commercial-grade performance in a reprogrammable slim package.
