CAT28C257 - 256K-Bit CMOS PARALLEL E2PROM
The CAT28C257 is a fast, low power, 5V-only CMOS Parallel E2PROM organized as 32K x 8-bits.
It requires a simple interface for in-system programming.
On-chip address and data latches, self-timed write cycle with autoclear and VCC power up/down write protection eliminate additional timing and protect
