OPERATION

R5104VxxxA (Watchdog Timer On/Off type)

The R5104VxxxA have the function that turns off the clock input of the watchdog timer. When the watchdog

timer is enabled (CE

="H"), the output of the internal regulator and SCK input pulse are supervised, while the

watchdog timer is disabled (CE

="L"), only the regulator is supervised.

R5104VxxxB (Standby Function)

Since the standby function is included in the R5104VxxxB, the consumption current of the system can be

reduced. The supply current at the standby mode is very small, typically 0.1µA.
