DESCRIPTION

The Microchip Technology Inc. 93C56/66 family of

Serial EEPROMs are configurable to either x16 or x8

organization. The ORG pin is used to select the

desired configuration. Advanced CMOS technology

makes this device ideal for low-power non-volatile

memory applications. The 93C56/66 are available in

the standard 8-pin DIP and 8-pin surface mount SOIC

package.

This device offers fast (1 ms) byte write and extended

(-40°C to +125°C) temperature operation. It is recommended that all other applications use Microchip's

93LC56/93LC66.
