MAX7389 - Microcontroller Clock Generator

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.

• a clock-speed select that reduces the output frequency by half. This functionality allows the microcontroller to operate at reduced power and may be used to extend the time available to perform housekeeping tasks, such as writing data to flash during a power failure. The MAX7389/MAX7390 clock outputs are factory programmed to a frequency in the 1MHz to 16MHz range. Four standard frequencies are available. Other frequencies are available upon r.
