Microchip 25AA080CT-I/SN: A Compact 8K SPI Serial EEPROM for Embedded Systems

The Microchip 25AA080CT-I/SN is an 8-kilobit Serial EEPROM device that utilizes the widely adopted SPI (Serial Peripheral Interface) bus for communication. This memory IC is designed for applications requiring reliable, non-volatile data storage with low power consumption and a small physical footprint. Its high-speed clock support of up to 10 MHz enables rapid data read and write operations, making it suitable for performance-sensitive embedded systems.

Organized as 1024 x 8 bits, this EEPROM offers byte-level and page-level write capabilities, providing flexibility for both small and moderate-sized data updates. The device includes critical features such as built-in hardware write protection via the HOLD pin and software protection through the WP (Write Protect) pin and status register bits. These mechanisms prevent accidental data modification, enhancing system reliability.

Operating at voltages from 1.8V to 5.5V, the 25AA080CT-I/SN supports a broad range of applications, including industrial control, automotive systems, consumer electronics, and IoT devices. Its extended temperature range (-40°C to +85°C) ensures stable performance in harsh environments. The compact SOIC-8 package allows for efficient PCB space utilization.

ICGOOODFIND: The Microchip 25AA080CT-I/SN stands out for its robust SPI interface, flexible write protection, and low-power operation, making it an ideal choice for modern embedded designs requiring dependable non-volatile memory.
