Description
25LC160AT-I/SN is Microchip’s 16‑Kbit I2C serial EEPROM (2,048 x 8). It stores nonvolatile data for microcontrollers and uses a two‑wire I2C interface up to 400 kHz. Packaged in an 8‑pin SOIC (SN) with industrial temperature range (-40°C to +85°C); A0–A2 address pins allow multiple devices on a bus, and WP provides write protection. Supply voltage is 2.7–5.5 V. Features include standard and fast I2C modes, random and sequential reads, and 16‑byte page writes. Typical write cycle time is 5 ms (max around 10 ms). Endurance is about 1,000,000 write cycles with data retention around 100 years. Suitable for config storage, calibration data, logs, and other small I2C memory needs in embedded systems.
