STM703

Note: 1. Reflow at peak temperature of 255°C to 260°C for < 30 seconds (total thermal budget not to exceed 180°C for between 90 to 150 seconds).

The STM690A/692A/STM703/704/802/805/817/818/ 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 VCC input for an out-oftolerance condition. When an invalid VCC condition occurs, the reset output (RST) is forced low (or high in the case of RST). These devices also offer a watchdog timer (except for STM703/704/ 819) as well as a power-fail comparator (except for STM818) to provide the system with an early warning of impending power failure.

These STM703 are available in a standard 8-pin SOIC package or a space-saving 8-pin TSSOP package.
