93LC66B-I/SN Description

Short technical summary and product information.

The 93LC66B-I/SN is a 4Kbit (256 x 16) serial Electrically Erasable Programmable Read-Only Memory (EEPROM) from Microchip Technology. This non-volatile memory device utilizes a Microwire (3-wire serial) interface for communication, making it suitable for applications requiring simple and reliable data storage.

 

Key electrical characteristics include a supply voltage range of 2.5V to 5.5V, a maximum clock frequency of 2 MHz, and a write cycle time of 6 ms per word or page. It is rated for industrial temperature operation from -40°C to +85°C (TA).

 

The device is offered in a surface-mount 8-SOIC package (8-SOIC 0.154", 3.90mm Width) with a supplier device package of 8-SOIC. Its compact form factor and low pin count make it easy to integrate into various electronic designs.
