Overview
The STM6322SWY6F is a 5-pin supervisor integrated circuit produced by STMicroelectronics. It is part of the STM6xxx family, which provides microprocessor supervisory functions. This device includes a precision voltage reference and comparator to monitor the VCC input for out-of-tolerance conditions. When an invalid VCC condition occurs, the reset output (RST) is forced low or high, depending on the configuration. The STM6322SWY6F is designed to ensure reliable operation of microprocessors and other digital systems by providing essential supervisory functions.
