- 8-pin PDIP through-hole package for easy prototyping and hand-soldering
- Matte tin terminal finish on leads for reliable solderability in standard PCB assembly
Applications
The 24LC16B-I/P is used in microcontroller-based systems to store configuration parameters, calibration coefficients, and device identification data that must survive power cycles. Its I2C interface requires only 2 signal lines plus power, making it easy to add persistent 16 Kbit storage to any design with an I2C bus. Consumer electronics, industrial sensors, and home appliance controllers commonly use this device for factory settings and user preference storage.

Frequently Asked Questions
How many bytes of non-volatile storage does 24LC16B-I/P provide and at what interface speed?
24LC16B-I/P offers 16 Kbits (2 KB) of EEPROM storage accessible over an I2C bus at up to 400 kHz in Fast Mode. This capacity is sufficient to hold hundreds of calibration coefficients, configuration records, or a small firmware parameter table without requiring an external flash chip.
Can 24LC16B-I/P be daisy-chained with other I2C devices on the same 2-wire bus?
Yes. 24LC16B-I/P has 3 hardware address pins allowing up to 8 devices on the same I2C bus, providing a combined 128 Kbits (16 KB) of non-volatile storage from a single 2-wire connection shared with other sensors or peripherals. All devices coexist as long as their 7-bit addresses are configured differently.
Why would an engineer choose the PDIP-8 package of 24LC16B-I/P over an SOIC-8 variant for a prototype board?
The 8-pin PDIP package has 2.54 mm pin pitch and standard 0.8 mm through-hole leads, which allows direct insertion into breadboards and perfboards without adapters. This makes 24LC16B-I/P the preferred choice during rapid prototyping, where hand-soldering and swap testing are routine, before switching to the surface-mount SOIC-8 variant for final PCB production.
