DESCRIPTION

• 8-pin PDIP/SOIC and 14-pin SOIC package

(SOIC in JEDEC and EIAJ standards)

• Temperature ranges supported

The Microchip Technology Inc. 93LC46/56/66 are 1K,

2K, and 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

93LC46/56/66 is available in standard 8-pin DIP and 8/

14-pin surface mount SOIC packages. The 93LC46X/

56X/66X are only offered in an “SN” package.

- Commercial (C):

- Industrial (I):

0°C to +70°C

-40°C to +85°C
