24LC32A in 24LCxx / AT24Cxx I2C EEPROM Family
The 24LC32A is a 32-Kbit (4K x 8) Serial Electrically Erasable PROM sub-family manufactured by Microchip Technology. Operating over a wide voltage range of 1.7V to 5.5V, these I2C-compatible devices are designed for low-power applications in non-volatile memory storage. They feature a 32-byte page write buffer and multiple address pins, allowing up to eight devices to share a single two-wire bus, making them a staple for configuration data and parameter storage in embedded systems.

| Part Number | Package | Stock |
|---|---|---|
| 24LC32A-I/P (Microchip Technology) | DIP-8 | 14,887 |
| 24LC32A-I/SN (Microchip Technology) | SOIC-8 | 13,475 |
Variants within the 24LC32A sub-family are distinguished primarily by their physical packaging and temperature ratings. Common packages include the 8-lead PDIP, SOIC, MSOP, and the ultra-thin TSSOP or DFN for space-constrained designs. Temperature grades range from industrial (-40 to +85 Celsius) to extended automotive grades (-40 to +125 Celsius), ensuring reliability across diverse operating environments while maintaining consistent electrical characteristics and I2C protocol timing.
