5V監(jiān)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) \;
