MAX7389/MAX7390 Microcontroller Clock Generator with Watchdog General Description The MAX7389/MAX7390 replace ceramic resonators, crystals, and supervisory functions for microcontrollers in 3.3V and 5V applications. The MAX7389/MAX7390 provide a clock source, reset, and watchdog functions. The watchdog timer is pin programmable and provides watchdog timeout values in the 16ms to 2048ms range. The MAX7389 provides a separate watchdog output that is used as a status indicator or to control safety-critical system elements. The MAX7390 Features a clock-speed select that reduces the output frequency by half. This functionality allows the microcontroller to operate at reduced power and may...
