STM690SM6F

The STM690SM6F is a 3V Supervisor with battery switchover. The supervisor is self-contained device which provide microprocessor supervisory functions with the ability to non-volatize and write-protect external LPSRAM. A precision voltage reference and comparator monitors the VCC input for an out-of-tolerance condition. When an invalid VCC condition occurs, the reset output (/RST) is forced low (or high in the case of RST). This device also offers a watchdog timer as well as a power-fail comparator to provide the system with an early warning of impending power failure.

• RST or /RST outputs
