Outline
This IC functions in a variety of CPU systems and other logic systems to generate a reset signal and reset the system accurately during momentary interruption or lowering of power supply voltage.
It also has a built-in watchdog timer for operation diagnosis. This prevents the system from running wild by generating an intermittent reset pulse during system mis-operation.
FEATUREs
1. Built-in watchdog timer
2. Low minimum operating voltage 130µA typ.
3. Low operating limit voltage VCC=0.8V
4. Watchdog stop function (RCT pin)
5. Long clock monitoring time
TPR (POWER ON) : TWD (clock monitoring)=1 : 5
6. Few external parts
APPLICATIONs
1. Reset circuits in microcomputers, CPUs and MPUs
2. Logic circuit reset circuits
3. Microcomputer system monitoring, etc.
