The Microchip 24LC08BT-E/OT: A Compact Powerhouse for Serial Data Storage

In the realm of embedded systems and IoT devices, efficient and reliable non-volatile memory is a fundamental component. The Microchip 24LC08BT-E/OT stands out as a premier solution, offering designers a robust and versatile 8 Kbit serial EEPROM in an incredibly space-saving package. This memory chip is engineered for applications where board space is at a premium and power consumption must be minimized, without compromising on data integrity or performance.

Operating over a broad voltage range of 1.7V to 5.5V, the 24LC08BT-E/OT is exceptionally suited for both low-power battery-operated devices and standard 3.3V or 5V systems. Its low-power design features a standby current of just 1 μA (max.), making it an ideal choice for power-sensitive applications. The device supports the ubiquitous I2C (Inter-Integrated Circuit) serial communication protocol, ensuring easy interfacing with a vast array of microcontrollers and processors. This two-wire interface simplifies design layout and reduces the number of GPIO pins required, streamlining the overall system architecture.

The internal 8 Kbit of memory is organized as a single block of 1024 x 8 (8-bit words). It features a 16-byte page write buffer, enabling more efficient data transfer by allowing up to 16 bytes to be written in a single operation. The chip incorporates advanced hardware data protection through hardware write-protection via a dedicated WP pin. When this pin is asserted, the entire memory array becomes immune to any write attempts, safeguarding critical data from accidental corruption.

Housed in a miniature 5-lead SOT-23 package, the SOT-23 package offers an ultra-small footprint, which is crucial for modern, miniaturized electronics. Despite its tiny size, the device is built to withstand demanding operating conditions, supporting over 1 million erase/write cycles and offering excellent data retention of over 200 years. Its extended temperature range (-40°C to +125°C) ensures reliable performance in industrial and automotive environments.

ICGOODFIND: The Microchip 24LC08BT-E/OT is a top-tier choice for designers seeking a high-performance, ultra-compact, and reliable serial EEPROM. Its combination of a wide voltage range, low power consumption, robust data protection, and a minuscule form factor makes it an indispensable component for portable consumer electronics, smart sensors, automotive modules, and industrial control systems.
