Frequently Asked Questions
How much data can the 24LC16B-I/ST store and what is its write endurance?
The 24LC16B-I/ST provides 16Kbit (2,048 bytes) of non-volatile EEPROM storage organized as 2K x 8 bits. It supports a minimum of 1,000,000 erase/write cycles per byte and guarantees data retention of at least 200 years, making it reliable for applications that frequently update calibration constants or configuration registers.
Which microcontroller bus speeds are compatible with the 24LC16B-I/ST I2C interface?
The 24LC16B-I/ST supports standard-mode I2C at 100kHz and fast-mode I2C at 400kHz, covering the two most common bus speeds used by 8-bit and 32-bit microcontrollers. Its 2.5V to 5.5V operating range means it integrates directly into both 3.3V and 5V MCU designs without level-translation circuitry.
For a compact IoT sensor design, how does the TSSOP-8 package of 24LC16B-I/ST help reduce board area?
The 8-pin TSSOP package of the 24LC16B-I/ST measures approximately 3.0 mm x 4.4 mm, offering a smaller footprint than a standard SOIC-8 package. This size reduction is valuable in IoT sensor nodes and wearable devices where PCB area is limited and a small non-volatile memory of 16Kbit is sufficient for storing sensor calibration coefficients and device identifiers.
