Catalyst CAT25C128/256 EEPROM Datasheet
The CAT25C128/256 EEPROM provides 128 Kbit or 256 Kbit memory organized as 16K×8 or 32K×8 bits. It operates via a standard SPI bus (compatible up to 5 MHz) with supply voltages from 1.8 V to 5.5 V, includes a 64‑byte page write buffer, and offers hardware and software write‑protect features. The device is supplied in 8‑pin DIP, 8‑pin SOIC, 14‑pin TSSOP and 20‑pin TSSOP packages.
Key electrical characteristics include a maximum operating current of 10 mA at 5 V/5 MHz, standby current as low as 10 yA, 100 k program/erase cycles, 100‑year data retention, and operation over industrial, automotive and extended temperature ranges (‑40 °C to +125 °C). Ordering information, pin configurations and revision history are also provided.
