Microchip Technology presents the 93AA66B-I-ST, a serial EEPROM component from the 93AA66 series. This CMOS device offers a memory density of 4 Kbit, organized as 256 words by 16 bits. It operates via the Microwire bus interface, supporting synchronous operation up to 1 MHz. The component features a wide supply voltage range from 1.8V to 5.5V, making it suitable for diverse power-constrained applications. Endurance is rated at 1 million write cycles, with a data retention exceeding 200 years. The 93AA66B-I-ST is housed in a PDSO8 (TSSOP8) package with a 0.65mm terminal pitch, designed for surface mounting. Typical applications include automotive systems, industrial control, and consumer electronics where non-volatile data storage is essential. Software write protection is a standard feature.
