DESCRIPTION
The CAT28C17A is a fast, low power, 5V-only CMOS parallel EEPROM organized as 2K x 8-bits. It requires a simple interface for in-system programming. On-chip address and data latches, self-timed write cycle with auto-clear and VCC power up/down write protection eliminate additional timing and protection hardware. DATA Polling and a RDY/BSY pin signal the start and end of the self-timed write cycle. Additionally, the CAT28C17A features hardware write protection.
