0 Volt Operation s 16 Byte Page Mode DESCRIPTION The CAT93CXXXX is a single chip solution to three popular functions of EEPROM memory, precision reset controller and watchdog timer.
The serial EEPROM memory of the 93CXXXX can be configured either by 16bits or by 8-bits.
Each register can be written (or read) by using the DI (or DO pin).
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.
It is designed to endure 1,000,000 program/erase cycles and has a data retention of 100 years.
