  • 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 an invalid VCCcondition occurs, the reset output (RST) is forced low (or high in the case of RST). These devices also offer a watchdog timer (except for STM704/795/806) as well as a power-fail comparator (except for STM795) to provide the system with an early warning of impending power failure.

    These devices are available in a standard 8-pin SOIC package or a space-saving 8-pin TSSOP package.

    Key Features

    • RST orRSToutputs
    • NVRAM supervisor for external LPSRAM
    • Chip enable gating (STM795 only) for external LPSRAM (7 ns max prop delay)
    • Manual (push-button) reset input
    • 200 ms (typ) trec
    • Watchdog timer - 1.6 s (typ)
    • Automatic battery switchover
    • Low battery supply current - 0.4 μA (typ)
    • Power-fail comparator (PFI/PFO)
    • Low supply current - 40 μA (typ)
    • GuaranteedRST(RST) assertion down to VCC= 1.0 V
    • Operating temperature: –40 °C to 85 °C (industrial grade)
    • RoHS compliance
      • Lead-free components are compliant with the RoHS directive
