The 24AA044-I/SN: A Robust 4K I²C Serial EEPROM Solution from Microchip

In the realm of embedded systems and IoT devices, the reliable and efficient storage of configuration data, calibration constants, or operational parameters is paramount. The 24AA044-I/SN from Microchip Technology stands out as a premier solution for these applications, offering a robust and highly accessible non-volatile memory in a compact package. This 4Kbit I²C Serial EEPROM is engineered to deliver performance, reliability, and ease of integration, making it a cornerstone component for countless designs.

A key feature of this memory chip is its organization of 512 x 8 (4Kbit), providing ample space for essential data without unnecessary overhead. Its operation across a broad voltage range of 1.7V to 5.5V makes it exceptionally versatile, capable of functioning in both modern low-power systems and legacy 5V designs. This wide operating voltage is crucial for battery-powered applications where voltage levels can fluctuate over the discharge cycle.

Communication is handled via the ubiquitous I²C (Inter-Integrated Circuit) protocol, which minimizes pin count and simplifies board layout. The 24AA044-I/SN supports a 400 kHz clock frequency, ensuring swift data transfer for time-sensitive operations. It also includes vital write-protection features; the entire array can be hardware write-protected using the dedicated WC (Write Control) pin, safeguarding critical data from accidental corruption.

For enhanced data integrity, the device incorporates built-in hardware write protection and a page write buffer that allows writes of up to 16 bytes at a time. Its low-power consumption characteristics are equally impressive, with a standby current of just 1 μA (max.) and an active read current of 1 mA (max.), which is essential for extending battery life in portable and remote applications. Housed in the space-efficient 8-lead SOIC (SN) package, it is ideal for designs with strict PCB area constraints.

In summary, the Microchip 24AA044-I/SN provides a perfect blend of capacity, performance, and reliability for serial memory requirements. Its industry-standard interface, low-power operation, and robust feature set ensure it remains a go-to choice for designers across the globe.
