DESCRIPTION
The Microchip Technology Inc. 93LC46/56/66 are 1K,
2K, and 4K low-voltage serial Electrically Erasable
PROMs. The device memory is congured 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.
