... Commercial Cypress Semiconductor Corporation Reprogrammable Registered PROM Functional Description The CY7C245A is a high-performance electrically pro- grammable, read only memory packaged in a slim 300-mil plastic or hermetic DIP. 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 intelligent programming algorithms ...

... The on-chip register timing requirements are similar to those of discrete registers available in the market. The CY7C245A has an asynchronous initialize input (INIT). The initialize function is useful during power-up and time-out sequences and can facilitate implementation of other sophisticated functions such as a built-in “ ...
