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).
