Overview
The STM810MWX6F is a low-power supervisory device from STMicroelectronics, designed to monitor power supplies and assert a reset signal when the supply voltage drops below a preset threshold. This component is part of the STM809/810/811/812 family of microprocessor reset circuits. It is particularly useful in ensuring the stable operation of microprocessors by maintaining the reset signal until the supply voltage has risen above the threshold for a specified period.
