Overview of 93LC66A-I/SN

The 93LC66A-I/SN is an EEPROM (Electrically Erasable Programmable Read-Only Memory) chip manufactured by Microchip Technology. It belongs to the 93LCxx series, which are low-power, 2-wire serial EEPROMs. The "93LC66A" part indicates its specific model within the series. The "I" signifies an industrial temperature range, typically between -40°C to 85°C, suitable for various industrial applications. The "SN" denotes the surface-mount package type, making it suitable for automated assembly processes on printed circuit boards.This EEPROM has a capacity of 4 kilobits, organized as 512 x 8 bits, providing non-volatile storage for small amounts of data. It operates using a simple 2-wire serial interface, making it easy to integrate into various electronic systems. With its electrically erasable and reprogrammable nature, users can modify stored data without requiring UV light or special equipment.
