MAX7390 - Microcontroller Clock Generator

This page provides the datasheet information for the MAX7390, a member of the MAX7389 Microcontroller Clock Generator family.

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.

Features

  • 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.

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.
