24LC64 in 24LCxx / AT24Cxx I2C EEPROM Family
The 24LC64 is a 64-Kbit I2C Serial Electrically Erasable PROM (EEPROM) family manufactured by Microchip Technology. It is designed for low-power applications and operates over a wide voltage range, typically from 1.7V to 5.5V. Utilizing a standard 2-wire serial interface, it provides a reliable non-volatile storage solution for configuration data, calibration constants, and user settings in various embedded systems while maintaining hardware compatibility with the industry-standard 24xx series footprint.

Comparing specs that differ across variants.
| Part Number | Package | Stock |
|---|---|---|
| 24LC64 (Microchip Technology) | SC-74A, SOT-753 | 18,317 |
| 24LC64-I/MS (Microchip Technology) | TSSOP-8 | 12,305 |
Variants within the 24LC64 sub-family are primarily distinguished by their package types and temperature ratings. Package options include 8-lead PDIP, SOIC, MSOP, and TSSOP, as well as ultra-thin DFN and chip-scale packages. Operating temperature grades range from industrial (-40°C to +85°C) to extended (-40°C to +125°C). Voltage range suffixing (e.g., LC vs. AA vs. FC) typically denotes different optimized operating voltage windows and clock speeds.
