The AT24C08D-MAHM-E: A High-Reliability 8-Kbit Serial EEPROM Solution

In the realm of embedded systems and IoT devices, the need for reliable, non-volatile memory for storing configuration data, calibration constants, and operational parameters is paramount. The AT24C08D-MAHM-E from Microchip Technology stands out as a robust and efficient solution, offering 8 Kbits (1024 bytes) of electrically erasable programmable read-only memory (EEPROM) in a compact package.

This memory IC utilizes the ubiquitous I2C (Inter-Integrated Circuit) serial communication protocol, making it incredibly simple to interface with a vast array of microcontrollers and processors. The use of a two-wire serial bus (Serial Clock - SCL and Serial Data - SDA) drastically reduces the number of I/O pins required, simplifying board layout and minimizing system cost. The device supports a 400 kHz clock frequency, enabling efficient data transfer rates for a wide range of applications.

A key feature of the AT24C08D is its internal organization and addressing scheme. The 8 Kbit of memory is arranged as 128 pages of 8 bytes each. This page structure is highly advantageous as it allows for faster write operations by enabling page writes of up to 8 bytes at a time, significantly improving overall system throughput compared to single-byte writing.

The AT24C08D-MAHM-E is designed for high reliability and endurance. It is specified for 1 million write cycles and a data retention period of 100 years, ensuring data integrity over the entire lifespan of the end product. The extended ‘-MAHM-E’ suffix denotes a lead-free (Green) device in a space-saving 8-lead UDFN package, making it ideal for modern, miniaturized consumer and industrial electronics.

Operating from a single 1.7V to 5.5V power supply, this EEPROM is exceptionally versatile, capable of functioning in both low-power battery-operated devices and standard 3.3V or 5V systems. Its low standby current consumption is critical for power-sensitive applications. Furthermore, the device incorporates a hardware write-protect pin, providing an extra layer of security against accidental data corruption.

Typical applications are widespread, including:

Smartphones, Televisions, and Set-Top Boxes

Industrial Automation and Sensor Data Logging

Medical Equipment and Automotive Systems

Gaming Consoles and Peripherals
