EPROM UV 64K-Bit 8K x 8 15ns 28-Pin Windowed CDIP

The CY7C265 is a 8192 x 8 registered PROM. It is organized as 8,192 words by 8 bits wide, and has a pipeline output register. In addition, the device features a programmable initialize byte that may be loaded into the pipeline register with the initialize signal. The programmable initialize byte is the 8,193rd byte in the PROM and its value is programmed at the time of use. Packaged in 28 pins, the PROM has 13 address signals (A0 through A12), 8 data out signals (O0 through O7), E/I (enable or initialize), and CLOCK. CLOCK functions as a pipeline clock, loading the contents of the addressed memory location into the pipeline register on each rising edge. The data will appear on the outputs if they are enabled. One pin on the CY7C265 is programmed to perform either the enable or the initialize function.
