5V监控器

The STM690A/692A/703/704/802/805/817/818/819 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 condit • 5 V operating voltage \n• NVRAM supervisor for external LPSRAM \n• Chip-enable gating (STM818 only) for external LPSRAM (7 ns max prop delay) \n• RST andRSToutputs \n• 200 ms (typ) trec \n• Watchdog timer - 1.6 sec (typ) \n• Automatic battery switchover• Low battery supply current - 0.4 μA (typ) \;
