OVERVIEW

The S24163 is a power supervisory device with 16,384-

bits of serial E2PROM. It is fabricated using SUMMIT's

advanced CMOS E2PROM technology and is suitable for

both 3 and 5 volt systems.

The S24163 is internally organized as 2048 x 8. It fea-

tures the I2C serial interface and software protocol allow-

ing operation on a simple two-wire bus.
