The X2804A is a 512 × 8‑bit E2PROM fabricated with Xicor’s N‑channel floating‑gate MOS technology. It offers simple byte‑write operation, self‑timed writes, and noise‑protected write enable. The device operates from a single 5 V supply and provides high reliability with 10 000 write cycles per byte and a data‑retention guarantee of 100 years.
Key electrical characteristics include an active current of up to 80 mA, standby current of 50 mA, a maximum byte‑write time of 10 ms, and a fast access time of 250 ns. The part supports a two‑line control architecture (CE and OE) for read/write operations and includes write‑protect features such as noise protection, Vcc sense, and write‑inhibit control.
