Microchip Technology's 93LC66C-E-SN is a CMOS serial EEPROM with a memory density of 4Kb. This component offers flexible memory organization, supporting either 256 words x 16 bits or 512 words x 8 bits configurations. It operates via a 3-wire serial interface, compatible with the Microwire bus protocol, and can achieve clock frequencies up to 3 MHz. The device features a wide operating voltage range from 1.8V to 5.5V and is rated for industrial temperature ranges of -40°C to +125°C. With an endurance of 1 million write cycles and data retention exceeding 200 years, it is suitable for applications requiring reliable non-volatile storage. The 93LC66C-E-SN is housed in an 8-lead PDSO package, ideal for surface-mount designs. Applications include automotive systems, industrial control, and consumer electronics.
