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 16-

bits 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, 8-

pin 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.

is selected. If the ORG pin is left unconnected, then an

internal pullup device will select the X16 organization.
