Holtek announces the release of two new integrated PIR/Microwave AFE and LDO Flash MCUs, the BA45F6630 and BA45F6622. The human body motion detection function can be implemented using an external PIR sensor or a microwave module. Using these devices results in a large reduction in the required number of external components and much simplified circuit design.
