General Description

The HT93LC66 is a 4K-bit low voltage nonvolatile, serial

electrically erasable programmable read only memory de-

vice using the CMOS floating gate process. Its 4096 bits of

memory are organized into 256 words of 16 bits each

when the ORG pin is connected to VCC or organized into

512 words of 8 bits each when it is tied to VSS. The device

is optimized for use in many industrial and commercial ap-

plications where low power and low voltage operation are

essential. By popular microcontroller, the versatile serial

interface including chip select (CS), serial clock (SK), data

input (DI) and data output (DO) can be easily controlled.
