Mastering Memory in Minimal Space: The Microchip 24LC16BT-E/OT 16K I²C Serial EEPROM

In the world of electronics design, the constant drive towards miniaturization demands components that deliver maximum functionality within the smallest possible footprint. The Microchip 24LC16BT-E/OT stands as a prime example, offering robust non-volatile memory in an incredibly compact SOT-23-5 package. This 16K I²C Serial EEPROM is engineered for applications where board space is at an absolute premium without compromising on performance or reliability.

This device organizes its 16 Kbits of memory as a single block of 2048 x 8 bits. It leverages the ubiquitous I²C (Inter-Integrated Circuit) protocol for communication, requiring only two pins for data (SDA) and clock (SCL), which dramatically reduces the number of I/O lines needed from the host microcontroller. This makes it an ideal choice for simplifying board layout and minimizing interconnect complexity. The 24LC16BT supports a 400 kHz clock rate, ensuring adequate speed for a wide range of data logging, configuration storage, and calibration setting applications.

A key feature of this EEPROM is its wide voltage operation range from 1.7V to 5.5V. This flexibility allows it to interface seamlessly with modern low-power microcontrollers operating at 1.8V or 3.3V, as well as legacy 5V systems, providing significant design versatility. Furthermore, it is designed for low-power operation, featuring a standby current of just 1 µA (max.), which is critical for battery-powered and portable devices.

Housed in a 5-lead SOT-23 package, this EEPROM is among the smallest in its class. The ultra-compact SOT-23-5 package is a game-changer for space-constrained designs such as wearable technology, miniature sensors, medical implants, and other portable consumer electronics. Despite its tiny size, the device does not sacrifice endurance or data retention, supporting 1,000,000 erase/write cycles and guaranteeing data retention for over 200 years.

The built-in hardware write-protection pin (WP) adds a layer of data security, allowing the host system to lock the memory array to prevent accidental or malicious data corruption. With an industrial temperature range of -40°C to +85°C, the 24LC16BT-E/OT is built to perform reliably in environmentally challenging conditions.

ICGOOODFIND: The Microchip 24LC16BT-E/OT is a superior solution for designers who need reliable, secure, and dense non-volatile memory in the smallest form factor. Its combination of a minuscule package, low-voltage operation, low power consumption, and high endurance makes it an excellent choice for pioneering the next generation of compact and intelligent electronic products.
