General Description
The HT93LC66 is a 4K-bit low voltage nonvola-
tile, serial electrically erasable programmable
read only memory device using the CMOS float-
ing gate process. Its 4096 bits of memory are or-
ganized 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 indus-
trial and commercial applications where low
powerandlowvoltageoperationareessential.By
popular microcontroller, the versatile serial in-
terface including chip select (CS), serial clock
(SK),datainput(DI)anddataoutput(DO)canbe
easily controlled.
