NXP公司的S32K是32位汽车通用MCU,工作电压2.7-5.5V,提供多种容量存储器,外设和封装选择.器件接纳ARM™ Cortex-M4F/M0+核,支持高达112MHz,具有1.25Dhrystone MIPS/MHz性能,集成了数字信号处理器(DSP)以及可配置嵌套矢量中断控制器(NVIC)以及单精度浮点单位(FPU),主要用在汽车电子,物联(IoT)智能毗连和马达控制.本文先容了S32K主要特点,框架图,评估板S32K144EVB主要特点,框架图和电路图,

The S32K series further extends the highly scalable portfolio of ARM®Cortex®MCUs in the automotive industry. It builds on the legacy of theKEA series, whilst introducing higher memory options alongside a richerperipheral set extending capability into a variety of automotiveapplications.

With a 2.70C5.5 V supply and focus on automotive environmentrobustness, the S32K series devices are well suited to a wide range ofapplications in electrical harsh environments. These devices are optimizedfor cost-sensitive applications offering low pin-count options.

The S32K series offers a broad range of memory, peripherals, andpackage options. They share common peripherals and pin counts allowingdevelopers to migrate easily within the MCU family or among the MCUfamilies to take advantage of more memory or feature integration. Thisscalability allows developers to standardize on the S32K series for their
end product platforms, maximizing hardware and software reuse andreducing timeto-market.

S32K is a scalable family of AEC-Q100 qualified 32-bit ARM Cortex-M4F and Cortex-M0+ based MCUs targeted for general purpose automotive and high reliability industrial applications.

Scalability C hardware and software compatible families with multiple performance, memory and feature options Integration C ISO CAN FD, CSEc hardware security, ASIL-B ISO26262 functional safety, ultra-low power performance Software C free automotive-grade Software Development Kit (SDK) and S32 Design Studio IDE, AUTOSAR & MCAL support, third party ecosystem.
