General Description

The HT93LC86 is a 16K-bit low voltage nonvolatile, serial electrically erasable programmable read only memory device 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 device 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 compose of (CS), serial clock (SK), data input (DI) and data output (DO).
