AN5426 Hardware Design Guidelines for S32K1xx Microcontrollers Application Note
●Introduction
■The S32K series further extends the highly scalable portfolio of ARM® Cortex® MCUs in the automotive industry. It builds on the legacy of the KEA series, whilst 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 series devices are well suited to a wide range of applications in electrical harsh environments. These devices are optimized for cost-sensitive applications offering low pin-count options.
■The S32K series offers a broad range of memory, peripherals, and package options. They share common peripherals and pin counts allowing developers to migrate easily within the MCU family or among the MCU families to take advantage of more memory or feature integration. This scalability allows developers to standardize on the S32K series for their end product platforms,maximizing hardware and software reuse and reducing time to market.
■Following are the general features of the S32K series MCUs:
▲32-bit ARM Cortex-M4 core with IEEE-754 compliant FPU, executing up to 112 MHz.
▲Scalable memory footprints up to 2 MB flash and up to 256 KB SRAM.
▲Precision mixed-signal capability with on chip analog comparators and multiple 12-bit ADCs.
▲Powerful timers for a broad range of applications including motor control,lighting control and body applications.
▲Serial communication interfaces such as LPUART, LPSPI, LPI2C,FlexCAN, CAN-FD and FlexIO.
▲SHE specification compliant security module.
▲Single power supply (2.70–5.5 V) with full functional flash program/erase/read operations.
▲Functional safety compliance with ISO26262, with internal watchdog,voltage monitors, clock monitors, memory protection and ECC.
▲Ambient operation temperature range: –40 °C to 125°C.
▲Software enablement: S32 Software Development Kit (SDK), S32 Design Studio (S32DS).
