The 24AA024HT-I/MNY from Microchip Technology represents a specialized solution for non-volatile memory storage in environments where elevated temperatures would render standard components inoperable. This 2-Kbit I2C Serial EEPROM is engineered to deliver reliable performance where it is needed most, pushing the boundaries of conventional operating conditions.

A key defining feature of this memory IC is its guaranteed high-temperature operation up to +125°C. This makes it an indispensable component for a wide array of demanding applications, including under-the-hood automotive systems, industrial control and automation, and downhole drilling instrumentation. In these scenarios, ambient temperatures can easily exceed the standard industrial range, necessitating components designed with robust thermal resilience.

Beyond its temperature rating, the 24AA024HT offers the familiar benefits of the I2C protocol, enabling communication with a simple 2-wire interface that minimizes board space and interconnect complexity. It supports a wide voltage range (1.7V to 5.5V), providing design flexibility across various power domains. The device also includes critical features for data integrity, such as built-in hardware write-protection to prevent accidental data modification and a page write buffer for more efficient programming cycles.

Internally organized as 256 x 8 bits, it ensures seamless compatibility with modern microcontrollers. Its extended temperature capability does not come at the expense of endurance or data retention; the device is specified for 1 million erase/write cycles and 200 years of data retention, ensuring long-term reliability in harsh conditions.
