Microchip 25AA160/25LC160/25C160 Serial EEPROM Datasheet
This document describes the 25AA160, 25LC160 and 25C160 16‑Kbit SPI serial EEPROM family. It includes electrical characteristics, pin descriptions, timing diagrams, and functional operation such as read and write sequences. The devices are offered in 8‑pin PDIP and SOIC packages and support industrial and automotive temperature ranges.
Key features include low‑power GMOS technology, block write protection, high endurance (1 M cycles), long data retention (>200 years), and ESD protection (>4000 V). The datasheet also provides detailed timing diagrams for HOLD, serial input, and serial output operations.
