93LC66 4K EEPROM – Datasheet

3,121 views

The 93LC66 is 4K, low-voltage serial Electrically Erasable PROMs. The device memory is configured as x8 or x16 bits, depending on the ORG pin setup. Advanced CMOS technology makes these devices ideal for low-power, nonvolatile memory applications. The 93LC66 is available in standard 8-pin DIP and 8/ 14-pin surface mount SOIC packages. The 93LC66 is only offered in an “SN” package.
