STM708RAM6F

STM708系列 2.63 V 160 ms 3 V 表面贴装 监控器 - SOIC-8

The STM705/706/707/708/813L supervisors are self-contained devices which provide microprocessor supervisory functions. 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 STM707/708 as well as a power-fail comparator 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.
