Supply voltage spans 1.7V to 5.5V, so it runs on a 1.8V rail without a level translator and also works in legacy 5V systems. The 450 ns access time at 1 MHz clock keeps the bus timing tight enough for most sensor calibration and configuration storage jobs. ## Package and mounting Housed in an 8-TSSOP package with a 4.40 mm body width. That's a small, low-profile part — the leads are fine-pitch but the body is thin, so it heats up fast under hot air. The thermal mass is low, so a standard 260°C peak reflow profile works without cooking the board.","metaTitle":"Microchip 24FC01T-E/ST 1Kbit I²C EEPROM, 450 ns","metaDescription":"Microchip 24FC01T-E/ST 1Kbit I²C EEPROM in 8-TSSOP. 450 ns access time, 1.7V-5.5V supply, -40°C to 125°C.
