Xicor XM28C040 4 Megabit E2PROM Module Datasheet
The XM28C040 is a high‑density 4 Megabit (512 K × 8) E2PROM module operating at 5 V. It offers an access time of 200 ns, supports three temperature ranges (Commercial 0 °C‑+75 °C, Industrial ‑40 °C‑+85 °C, Military ‑55 °C‑+125 °C), and provides 100 000 write‑cycle endurance. The module uses a 256‑byte page‑write architecture that can rewrite the entire array in about 10 seconds.
Key features include fast write cycles (≈5 ms per byte), DATA Polling and Toggle‑Bit status bits for write‑completion detection, and both hardware (noise protection, VCC sense, write‑inhibit) and software data‑protection mechanisms that can be enabled via a defined command sequence.
