The 93C66CT-I/MC is an 8-pin memory storage device manufactured by Microchip Technology. It is an electrically erasable programmable read-only memory (EEPROM) that can store 64 bits of non-volatile data in two different formats—byte-wide and word-wide. It is ideal for storing settings and other data in a variety of applications, such as data-logger devices, factory automation systems, embedded controllers, and wearable devices. The 93C66CT-I/MC offers a very low standby current, reliability in various temperature ranges, error correction capability, and up to 1 million write/erase cycle endurance. It is available in an 8-pin PDIP, SOIC, or TSSOP package.
