Key Features

  • 16-Kbit EEPROM with 400 kHz I2C interface for simple 2-wire integration in space-constrained designs
  • 1,000,000 write-cycle endurance and 200-year data retention for long-life embedded storage
  • 2.5 V to 5.5 V operating range in a 5-pin SOT-23 package compatible with 3.3 V and 5 V MCU systems

Applications

The 24LC16BT-I/OT is used in consumer electronics, industrial controllers, and IoT devices requiring compact, reliable non-volatile parameter storage over I2C. Its 2-wire interface and SOT-23 package make it a drop-in storage solution for microcontrollers managing calibration data, configuration settings, or device identification across a 2.5 V to 5.5 V supply range. The 16-byte page write buffer and 400 kHz bus speed support efficient sequential writes in data-logging and firmware-configuration applications.

Frequently Asked Questions

How does the 24LC16BT-I/OT's 2-wire I2C interface simplify integration with low-pin-count microcontrollers?

The 24LC16BT-I/OT communicates over a standard 2-wire I2C bus at up to 400 kHz, requiring only two signal lines (SDA and SCL) from the host MCU. This minimal pin usage makes it especially practical for small microcontrollers with limited I/O, and the SOT-23-5 package reduces PCB area to under 10 mm², leaving more space for the rest of the system.

What write endurance and data-retention specifications should designers rely on for the 24LC16BT-I/OT in industrial equipment?

The 24LC16BT-I/OT is rated for 1,000,000 write cycles per page and data retention of 200 years at 25°C. For industrial equipment updating calibration constants or event logs infrequently, this endurance far exceeds the product's operational lifetime. The 16-byte page write buffer allows up to 16 bytes to be written in a single bus transaction, reducing I2C overhead.

When is the 24LC16BT-I/OT a more practical choice than a larger EEPROM such as 24LC64 for a sensor design?

For sensors storing a small, fixed set of calibration coefficients, device IDs, or configuration bytes totalling under 2 KB, the 24LC16BT-I/OT's 16-Kbit (2 KB) capacity is sufficient and avoids paying for excess memory. Its SOT-23-5 package is smaller than the SOT-23-8 or SOIC-8 packages used by higher-capacity devices, directly reducing PCB area and bill-of-materials cost in high-volume production.
