Microchip 24AA08HT-I/MNY: A Robust 8K I2C Serial EEPROM for Demanding Environments

In applications where reliability under extreme thermal conditions is non-negotiable, the Microchip 24AA08HT-I/MNY stands out as a specialized memory solution. This 8 Kbit serial EEPROM is engineered to deliver consistent performance where standard commercial-grade components would fail, making it an indispensable component for automotive, industrial, and aerospace systems.

A defining feature of this device is its extended high-temperature operational capability. Unlike conventional EEPROMs rated for up to 85°C, the 24AA08HT-I/MNY is guaranteed to operate across a temperature range of -40°C to +125°C. This ensures data integrity and reliable communication in harsh under-the-hood automotive environments or on high-temperature industrial processing lines.

The memory is organized as 1024 x 8 and supports the ubiquitous I2C (Inter-Integrated Circuit) serial interface, facilitating easy communication with a vast array of microcontrollers and processors. It supports a 400 kHz clock speed, enabling efficient data transfer. The inclusion of hardware write-protection pins provides an additional layer of security against accidental data modification.

Packaged in a space-saving 8-contact TDFN (2x3mm) known as Microchip’s “Microchip” package, the 24AA08HT-I/MNY offers a minimal footprint. This is critical for modern, miniaturized electronic designs where board real estate is at a premium. Its low power consumption further enhances its suitability for power-sensitive applications.

ICGOOODFIND: The Microchip 24AA08HT-I/MNY is a high-reliability EEPROM that excels in extreme thermal conditions. Its combination of a wide -40°C to +125°C operating range, standard I2C interface, and ultra-small package makes it a superior choice for designers who need robust non-volatile memory for demanding automotive, industrial, and embedded systems.
