eneral Description The MAX7387/MAX7388 replace ceramic resonators, crystals, and supervisory functions for microcontrollers in 3.3V and 5V applications. The MAX7387/MAX7388 provide a clock source together with integrated reset, watchdog, and power-fail functions. The watchdog timer is pin programmable and provides watchdog timeout values in the 16ms to 2048ms range. The power-fail output provides early warning of power failure. The power-fail threshold on the MAX7388 is internally set. The MAX7387 also provides a separate watchdog output that is used as a status indicator or to control safety-critical system elements.
