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.

Note: When the ORG pin is connected to VCC, the X16 organiza
tion is selected. When it is connected to ground, the X8 pin
is selected. If the ORG pin is left unconnected, then an
internal pullup device will select the X16 organization.
