The XL2865A is an 8K × 8‑bit E2PROM with fast read access times as low as 250 ns and a standby current under 50 mA. It operates from a single 5 V supply and includes a READY/BUSY status pin, automatic 32‑byte page write, and data‑polling features for efficient non‑volatile writes.
The device offers up to 10 years of data retention, 10 000 rewrites per byte, and a maximum write cycle time of 10 ms. It is supplied in several packages (28‑pin PDIP, 28‑pin CERDIP, 32‑pin PLCC) and is compatible with standard 8K × 8 E²PROMs, making it suitable for industrial controllers, telemetry, and other applications requiring reliable non‑volatile storage.
