Applications
The 24LC16BI/P is used to store non-volatile configuration data, calibration coefficients, and device serial numbers in microcontroller-based embedded systems across consumer electronics, industrial instruments, and IoT sensor modules. Its 2-wire I2C interface connects directly to virtually any microcontroller with minimal pin usage, making it a cost-effective solution for small data retention tasks such as preserving user settings across power cycles. The through-hole DIP-8 package is well suited for prototyping, repair applications, and designs where through-hole mounting is preferred over SMD.

Frequently Asked Questions
How much data can the 24LC16BI/P store, and how is the memory organized?
The 24LC16BI/P provides 16 Kb of non-volatile EEPROM storage, organized as 2048 bytes (2 KB) addressable individually or in pages of 16 bytes. This capacity is sufficient for storing firmware configuration tables, sensor calibration data, device identifiers, and user-adjustable parameters in embedded systems that need persistent data retention without battery backup.
What communication interface does the 24LC16BI/P use, and at what bus speed does it operate?
The 24LC16BI/P uses the I2C-compatible 2-wire serial interface, supporting standard-mode operation at 100 kHz and fast-mode at 400 kHz. This dual-speed support allows the host microcontroller to communicate at higher throughput when reading or writing calibration blocks, reducing data transfer time in applications that perform frequent EEPROM accesses.
What supply voltage range does the 24LC16BI/P support, and does it work with 3.3 V microcontrollers?
The 24LC16BI/P operates over a supply voltage range of 2.5 V to 5.5 V, covering both 3.3 V and 5 V microcontroller I/O standards. This wide range means the same device can be used in mixed-voltage systems without additional level shifting, and it will continue to operate reliably as battery-powered supply rails drop during discharge cycles.
How does the page write feature of the 24LC16BI/P improve write performance compared to byte writes?
The 24LC16BI/P supports page writes of up to 16 bytes in a single I2C transaction, compared to 1 byte per write cycle for byte-mode writes. Since each write cycle on EEPROM includes an internal programming time of approximately 5 ms, writing a 16-byte page in one cycle instead of 16 individual byte writes reduces total write time from ~80 ms to ~5 ms, an 16x improvement for block data updates.
