The Microchip AT24C04C-MAHM-T: A Robust 4-Kbit Serial EEPROM for I2C Systems
In the realm of embedded systems and IoT devices, reliable non-volatile memory is a fundamental component for storing critical data. The Microchip AT24C04C-MAHM-T stands out as a high-performance, serial Electrically Erasable Programmable Read-Only Memory (EEPROM) solution designed for a vast array of applications. This 4-Kbit (512 x 8) memory chip provides a simple and efficient method for adding parameter storage to systems utilizing the ubiquitous I2C protocol.
A key feature of this EEPROM is its utilization of the industry-standard two-wire I2C serial interface. This design minimizes the number of I/O pins required for communication, making it an ideal choice for space-constrained PCB designs and for systems where microcontroller pin count is at a premium. The device supports a 400 kHz clock frequency, enabling efficient and speedy data transfer for most common use cases.

The AT24C04C-MAHM-T offers enhanced data integrity and design flexibility. It is organized as two blocks of 256 x 8 bits each. A built-in hardware write-protect pin provides an essential safety feature, allowing the entire memory array to be protected against inadvertent write operations, thus safeguarding sensitive data from corruption. Furthermore, the device boasts exceptional reliability with a endurance of over 1 million write cycles and a data retention period exceeding 100 years, ensuring long-term performance and value.
Housed in a compact and robust 8-pin Ultra Thin Mini-MOLD (UDFN) package (MAHM), this chip is well-suited for modern, miniaturized consumer electronics, including smart appliances, industrial controls, telecommunication systems, and wearable technology. Its low power consumption is perfectly aligned with the demands of battery-powered portable devices.
