STMicroelectronics STM690A/STM692A/STM703/STM704/STM802/STM805/STM817/STM818/STM819 Supervisor Manual
The STM690A, STM692A, STM703, STM704, STM802, STM805, STM817, STM818 and STM819 supervisors are 5 V supervisory devices that provide reset, watchdog, battery‑switchover and power‑fail monitoring for microprocessor systems. They are offered in 8‑pin SOIC and TSSOP packages and support external LPSRAM non‑volatile storage.
The manual includes functional block diagrams, pin descriptions, timing waveforms, electrical characteristics, package mechanical data, ordering information and a revision history. It serves designers and system integrators who need to implement reliable power‑management and reset control in their designs.
