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.

COMMENT
Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
These are stress ratings only, and functional operation
of the device at these or any other conditions outside of
those listed in the operational sections of this specifica-
tion is not implied. Exposure to any absolute maximum
rating for extended periods may affect device perfor-
mance and reliability.
