General Description
The HT93LC86 is a 16K-bit low voltage nonvolatile, serial
electrically erasable programmable read only memory de-
vice using a CMOS floating gate process. Its 16384 bits of
memory are organised into 1024 words of 16 bits each
when the ORG pin is connected to VCC or organised into
2048 words of 8 bits each when it is tied to VSS. The de-
vice is especially suitable for use in many industrial and
commercial applications where low power and low voltage
operation are essential. The device can easily interface to
microcontrollers using the versatile serial interface com-
pose of (CS), serial clock (SK), data input (DI) and data
output (DO).
