3V监控器

The STM690/704/795/802/804/805/806 supervisors are self-contained devices which provide microprocessor supervisory functions with the ability to non-volatize and write-protect external LPSRAM. A precision voltage reference and comparator monitors the VCCinput for an out-of-tolerance condition. When • RST orRSToutputs \n• NVRAM supervisor for external LPSRAM \n• Chip enable gating (STM795 only) for external LPSRAM (7 ns max prop delay) \n• Manual (push-button) reset input \n• 200 ms (typ) trec \n• Watchdog timer - 1.6 s (typ) \n• Automatic battery switchover• Low battery supply current - 0.4 μA;
