AT24C32E in 24LCxx / AT24Cxx I2C EEPROM Family
The AT24C32E series by Microchip Technology is a 32-Kbit I2C compatible serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) organized as 4,096 words of 8 bits each. Optimized for industrial and commercial applications, this device operates across a wide voltage range of 1.7V to 3.6V. It features high-speed performance with a 1MHz clock frequency at 2.5V and above, providing reliable non-volatile storage for systems requiring frequent byte or page writes in space-constrained environments.
Variants in This Sub-Family
Variants within the AT24C32E sub-family differ primarily by package type and temperature rating. Common packages include the 8-lead JEDEC SOIC, 8-lead TSSOP, and ultra-thin UDFN or VFBGA options for high-density layouts. Specific suffixes like '-SSHM' denote the SOIC package with NiPdAu lead finish, while industrial temperature ratings ensure reliable operation from -40C to +85C. Tape and reel versus tube packaging options are also specified via the 'T' or 'B' suffix.
