Microchip Technology presents the 93C66B-E-MS, a 4Kb serial EEPROM designed for robust data storage applications. This CMOS device features a memory organization of 256 words by 16 bits, accessible via a 3-wire Microwire serial interface with a maximum clock frequency of 3 MHz. The component offers a wide operating voltage range from 4.5V to 5.5V and operates across an industrial temperature range of -40°C to +125°C.
With a data retention capability of 200 years and an endurance rating of 1 million write cycles, the 93C66B-E-MS is suitable for applications requiring long-term data integrity and frequent updates. It supports software write protection and a toggle bit for efficient status monitoring. The device is housed in an 8-lead TSSOP package with a 0.65mm terminal pitch, ideal for space-constrained designs. This component finds application in automotive, industrial control, and consumer electronics segments.
