The CAT1161/2 is a complete memory and supervisory
solution for microcontroller-based systems. A serial
EEPROM memory (16K) with hardware memory write
protection, a system power supervisor with brown out
protection and a watchdog timer are integrated together
in low power CMOS technology. Memory interface is via
an I2C bus.
The 1.6-second watchdog circuit returns a system to a
known good state if a software or hardware glitch halts
or “hangs” the system. The CAT1161 watchdog monitors
the SDA line, making an additional PC board trace
unnecessary. The lower cost CAT1162 does not have a
watchdog timer.
