- Commercial (C):

- Industrial (I):

0°C to +70°C

-40°C to +85°C

The Microchip Technology Inc. 93LC66A/B are 4K-bit,

low voltage serial Electrically Erasable PROMs. The

device memory is configured as x8 (93LC66A) or

x16 bits (93LC66B). Advanced CMOS technology

makes these devices ideal for low power nonvolatile

memory applications. The 93LC66A/B is available in

standard 8-pin DIP, surface mount SOIC, and TSSOP

packages. The 93LC66AX/BX are only offered in a

150-mil SOIC package.
