The STMicroelectronics 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 of tolerance condition. When an invalid VCC condition occurs, the reset output is forced low. RoHS compliance
