Product Summary
The CAT1161JI-42 is a supervisory circuits with i2c serial cmos eeprom, precision reset controller and watchdog timer. The CAT1161JI-42 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 CAT1161JI-42 watchdog monitors the SDA line, making an additional PC board trace unnecessary.
