24LC16BT-I/OT

A: The device operates over a wide supply voltage range of 2.5 V to 5.5 V and an industrial temperature range of –40 °C to +85 °C. It supports I²C clock frequencies of 100 kHz and 400 kHz, with a typical access time of 900 ns. Key features include a self‑timed write cycle of 5 ms maximum, a 16‑byte page write buffer, hardware write‑protect, low standby current of just 1 µA (typical), and active current of 1 mA (typical). The device also offers ESD protection exceeding 4,000 V.

A: The 24LC16BT-I/OT communicates via an I²C (2‑wire) serial bus consisting of the Serial Data line (SDA) and the Serial Clock line (SCL). The device operates as a slave on the bus, with a control byte of 1010xxMR where M selects the memory block (bank) and R denotes read/write. Since external address pins (A0, A1, A2) are not present on the SOT‑23 package, the three MSB bits in the control byte (bits b3, b4, b5) are used to select one of the eight 256‑byte blocks. This internal block‑addressing scheme allows all eight blocks to be accessed without physical address pins. The device supports single‑byte writes and 16‑byte page writes, which are self‑timed and require no external timing control.

A: The 24LC16BT-I/OT is rated for a minimum endurance of 1,000,000 write/erase cycles per memory cell, ensuring long‑term reliability for applications that require frequent data updates. In addition, the device guarantees a data retention time of more than 200 years, making it suitable for storing critical configuration data and calibration values that must remain intact for extended periods.

A: Thanks to its small footprint, low power consumption, wide operating voltage range, and industrial temperature rating, the 24LC16BT-I/OT is ideal for space‑constrained and battery‑powered applications. Typical use cases include storing configuration settings, calibration data, and user preferences in embedded systems, IoT devices, consumer electronics (such as smart TVs and audio equipment), industrial control systems, and automotive electronic control units (ECUs). Its non‑volatile memory ensures that stored data remains intact when power is removed.
