CAT93CXXXX (1K-16K)
Supervisory Circuits with Microwire Serial CMOS E2PROM, Precision Reset Controller and Watchdog Timer
FEATURES
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.
