Microchip 24AA024-I/SN: A Robust 2-Wire Serial 2Kbit EEPROM Memory Solution
In the realm of embedded systems and IoT devices, the need for reliable, non-volatile memory for data storage and configuration parameters is paramount. The Microchip 24AA024-I/SN stands out as a highly integrated, low-power 2Kbit I2C serial EEPROM memory chip designed to meet these critical demands. This device provides a simple and efficient method for adding small-scale, persistent memory to a wide array of applications, from consumer electronics to industrial systems.
Operating over a broad voltage range (1.7V to 5.5V), the 24AA024-I/SN is exceptionally versatile, supporting both low-power and standard systems. Its 2-wire serial interface (I2C compatible) simplifies design integration, requiring only two bidirectional lines (SDA and SCL) for communication, thereby minimizing the microcontroller's pin count and reducing board space. This makes it an ideal choice for space-constrained designs.

The memory is organized as 256 x 8 (256 bytes) and features hardware write-protection via a dedicated WP (Write-Protect) pin. When asserted, this pin locks the entire memory array, preventing accidental data corruption—a crucial feature for securing vital calibration or configuration data. Furthermore, the chip supports page write operations of up to 16 bytes, allowing for efficient data throughput and faster programming cycles.
With its high reliability, 1,000,000 erase/write cycles, and data retention of over 200 years, the 24AA024-I/SN ensures data integrity over the entire lifespan of a product. Its low power consumption is equally impressive, with a standby current of just 1 μA (max), making it perfectly suited for battery-powered and portable applications. Available in the compact 8-lead SOIC (SN) package, it is tailored for modern, high-density PCB designs.
ICGOOODFIND: The Microchip 24AA024-I/SN is a quintessential component for designers seeking a low-power, high-reliability, and compact non-volatile memory solution. Its industry-standard I2C interface, robust data protection features, and proven endurance make it a go-to choice for ensuring data persistence in countless electronic designs.
