DESCRIPTION

The reset function of the 93CXXXX protects the system during brown out and power up/down conditions. During system failure the watchdog timer feature protects the microcontroller with a reset signal. Catalyst's advanced CMOS technology substantially reduces device power requirements. The 93CXXXX is available in 8-pin DIP, 8pin TSSOP or 8-pin SOIC packages.
