About this manual

The 25AA1024 and 25LC1024 are 1 Mbit Serial Flash devices that combine Flash and byte‑level EEPROM functions. They communicate over a standard SPI bus and support a wide supply range, low‑power operation, and built‑in write protection features. The devices are offered in PDIP, SOIC, and DFN packages with Pb‑free options.

Key features include a maximum clock frequency of 20 MHz, 256‑byte page size, sector and chip erase capabilities, and endurance of 100 k erase/write cycles. The parts operate from –40 °C to +85 °C (industrial) or –40 °C to +125 °C (automotive) and provide deep‑power‑down standby current of 1 µA.
