S32K1xx Series Reference Manual 用戶手冊--2029頁 Supports S32K116, S32K118, S32K142, S32K144, S32K146, and S32K148S32K是一款符合AEC-Q100規范、基于32位ARM Cortex-M4F和Cortex-M0+內核的MCU，適用于通用汽車和高可靠性工業應用。The S32K1xx product series further extends the highly scalable portfolio of Arm? Cortex?-M0+/M4F MCUs in the automotive industry. It builds on the legacy of the KEA series, while introducing higher memory options alongside a richer peripheral set extending capability into a variety of automotive APPlications. With a 2.70–5.5 V supply and focus on automotive environment robustness, the S32K product series devices are well suited to a wide range of APPlications in electrically harsh environments, and are optimized for cost-sensitive APPlications offering low pin-count options. The S32K product series offers a broad range of memory, peripherals, and package options. It shares common peripherals and pin counts, allowing developers to migrate easily within an MCU family or among the MCU families to take advantage of more memory or feature integration. This scalability allows developers to use the S32K product series as the standard for their end product platforms, maximizing hardware and software reuse and reducing time to market

DescriptionThe IMX385LQR-C is a diagonal 8.35 mm (Type 1/2) CMOS active pixel type solid-state image sensor with a squarepixel array and 2.13 M effective pixels. This chip operates with analog 3.3 V, digital 1.2 V, and interface 1.8 V triplepower supply, and has low power consumption. High sensitivity, low dark current and no smear are achieved throughthe adoption of R, G and B primary color mosaic filters. This chip features an electronic shutter with variablecharge-integration time.(APPlications: Surveillance cameras)

MotioninterfaceTM is becoming a "must-have"function being adopted by smartphone and tablet manufacturers due to the enormous value it adds to the end user experience. In smartphones, it finds use in APPlications such as gesture commands for APPlications and phone control, enhanced gaming, augmented reality, panoramic photo capture and viewing, and pedestrian and vehicle navigation. With its ability to precisely and accurately track user motions, MotionTracking technology can convert handsets and tablets into powerful 3D intelligent devices that can be used in APPlications ranging from health and fitness monitoring to location-based services. Key requirements for Motionlnterface enabled devices are small package size, low power consumption, high accuracy and repeatability, high shock tolerance, and application specific performance programmability-all at a low consumer price point.
