Microchip 24AA024HT-I/ST: A Robust 2-Wire Serial EEPROM for Demanding Environments

In the realm of non-volatile memory solutions, the Microchip 24AA024HT-I/ST stands out as a specialized EEPROM designed for reliability under extreme thermal stress. This 2-Kbit (256 x 8) serial EEPROM is engineered for applications where consistent data retention and endurance are critical, particularly in high-temperature environments where standard commercial-grade components would falter.

A defining feature of this device is its exceptional high-temperature endurance. It is specified to operate seamlessly within a temperature range of -40°C to +125°C, making it an ideal choice for automotive, industrial, and aerospace applications. These sectors often require electronics to function reliably near engines, in control systems, or on factory floors where ambient temperatures can soar. The 24AA024HT-I/ST guarantees data integrity and full functional performance across this entire spectrum, ensuring that critical calibration data, configuration settings, or event logs are preserved.

The memory utilizes a 2-wire serial interface (I²C™ compatible), which simplifies board design and reduces the number of GPIO pins required from the host microcontroller. This interface supports communication at speeds up to 400 kHz, providing efficient data transfer for a wide array of embedded systems. The device also features hardware write-protection on the entire array, offering an additional layer of security against accidental data corruption.

Beyond its thermal resilience, this EEPROM is built for longevity. It boasts a remarkable endurance of 1,000,000 erase/write cycles per cell and offers a data retention period of over 200 years. Such robustness ensures the device can handle frequent data updates throughout the extended lifespan of a product.

Housed in a space-saving TSSOP-8 package, the 24AA024HT-I/ST is designed for high-density PCB layouts. Its low power consumption further enhances its suitability for power-sensitive applications.
