93AA66A-I/SN Description

Short technical summary and product information.

The 93AA66A-I/SN is a 4Kbit serial EEPROM from Microchip Technology using the Microwire interface. It is organized as 512 x 8 bits and operates over a wide voltage range of 1.8V to 5.5V, making it suitable for battery-powered and low-voltage applications.

 

The device is offered in an 8-pin SOIC package (SOIC-8), which is common for surface-mount assembly. The Microwire serial interface allows easy integration with microcontrollers and other digital systems.

 

Typical applications include parameter storage, device configuration, and calibration data retention in industrial, automotive, and consumer electronics. The EEPROM supports reliable non-volatile storage with fast access times suited for moderate-speed data exchange.
