Overview
The STM795RM6F is a microprocessor supervisor IC produced by STMicroelectronics. It is part of the STM690/704/795/802/804/805/806 series, designed to provide comprehensive supervisory functions for microprocessors. This device includes features such as a precision voltage reference and comparator to monitor the VCC input for out-of-tolerance conditions, and it can force the reset output (RST) low or high when such conditions occur. The STM795RM6F also supports automatic battery switchover and has a low supply current, making it suitable for various embedded systems and power management applications.
