... The memory cells utilize proven EPROM floating gate technology and byte-wide intelligent programming algorithms. The CY7C235A replaces bipolar devices pin for pin and offers the advantages of lower power, superior performance, and high programming yield. The EPROM cell requires only 12.5V for the supervoltage, and low current requirements allow for gang programming ...

... The on-chip register timing requirements are similar to those of discrete registers available in the market. The CY7C235A has an asynchronous initialize input (INIT). The initialize function is useful during power-up and time-out sequences and can facilitate implementation of other sophis- ticated functions such as a built-in “ ...
