24LC16B in 24LCxx / AT24Cxx I2C EEPROM Family
The 24LC16B family, manufactured by Microchip Technology, consists of 16-Kbit I2C serial Electrically Erasable PROMs (EEPROMs). These components are industry-standard non-volatile memory solutions designed for low-power applications. Organized as eight blocks of 256 x 8-bit memory, they utilize a simple two-wire serial interface and provide reliable data retention for up to 200 years. They are primarily used for storing configuration constants, calibration data, and user preferences in cost-sensitive embedded systems.
Variants in This Sub-Family
Comparing specs that differ across variants.
| Part Number | Package | Stock |
|---|---|---|
| 24LC16B-I/P (Microchip Technology) | DIP-8 | 4,973 |
| 24LC16B-I/SN (Microchip Technology) | SOIC-8 | 3,322 |
| 24LC16B (Microchip Technology) | SC-74A, SOT-753 | 113,884 |
Variants within the 24LC16B sub-family are distinguished primarily by their physical packaging and temperature ratings. Package options include 8-lead PDIP, SOIC, TSSOP, MSOP, and smaller 5-lead SOT-23 or DFN formats. Temperature grades range from Industrial (-40°C to +85°C) to Extended (-40°C to +125°C). While the underlying silicon die remains consistent across these variants, the suffix in the part number (e.g., -I/P or -I/SN) specifies the mechanical footprint and thermal performance.
