Microchip Technology 93AA66CT-I/SN Serial EEPROM

The 93AA66CT-I/SN is a 4Kb Serial EEPROM designed and manufactured by the renowned Microchip Technology. This high-quality memory device offers a convenient and reliable way to store data that must be preserved during power-off scenarios. Utilized widely in various electronic applications, the 93AA66CT-I/SN is an essential component for system configuration, device calibration, and product tracking.

Ensuring compatibility with a wide range of microcontroller (MCU) interfaces, the 93AA66CT-I/SN operates via a standard SPI (Serial Peripheral Interface) bus. This interface is well-known for its simplicity and effectiveness, allowing for easy integration into existing designs. The EEPROM supports a bus clock frequency of up to 10 MHz, enabling quick data access and programming operations, which is crucial for performance-critical applications.

This device offers a robust storage solution with a memory size of 4 Kb, organized as 256 x 16-bit or 512 x 8-bit, selectable via software. It also features a self-timed erase and write cycle, meaning no external timing is required for write operations. The 93AA66CT-I/SN includes write protection mechanisms to prevent accidental data corruption, increasing the reliability of the stored information.

The 93AA66CT-I/SN comes in an 8-pin SOIC (Small Outline Integrated Circuit) package, which is ideal for space-constrained applications. Its industrial temperature range of -40°C to +85°C ensures stable operation under extreme conditions, making it suitable for a wide array of industrial and commercial environments.

Microchip Technology's commitment to quality is evident in the 93AA66CT-I/SN, with its endurance of 1 million erase/write cycles and data retention of over 200 years. This guarantees that the EEPROM will not only perform reliably over the product's lifetime but will also maintain data integrity for an extended period.
