=========== NXP S32K1XX =========== The `S32K1XX series `_ is a family of automotive-grade general-purpose microcontrollers from NXP Semiconductors. The lower end of the family is based on an Arm Cortex-M0+ core and can run at clockspeeds up to 48 MHz. The higher end chips are based on the Arm Cortex-M4F core which runs at up to 80 or 112 MHz. Supported MCUs ============== The following list includes MCUs from the S32K1XX series and indicates whether they are supported in NuttX: ======== ======= ========== ========= MCU Support Core Frequency ======== ======= ========== ========= S32K116 Yes* Cortex-M0+ 48 MHz S32K118 Yes* Cortex-M0+ 48 MHz S32K142 Yes* Cortex-M4F 112 MHz S32K144 Yes Cortex-M4F 112 MHz S32K146 Yes Cortex-M4F 112 MHz S32K148 Yes Cortex-M4F 112 MHz S32K142W No** Cortex-M4F 80 MHz S32K144W No** Cortex-M4F 80 MHz ======== ======= ========== ========= | \* Supported but (mostly) untested. | ** Not supported (yet), but it is expected that existing code can be adapted with limited effort. Supported Modules & Peripherals =============================== The following list indicates modules and peripherals supported in NuttX. Note that this list does not include all MCU modules. Please refer to the S32K1XX Reference Manual for a complete overview of its features. ========== ======= ========================== Peripheral Support Comments ========== ======= ========================== ADC No CMP No eDMA No EEEPROM Yes EEPROM emulated by FlexRAM ENET Yes FlexCAN Yes SocketCAN-compatible FlexIO No FTM Yes PWM driver only GPIO Yes LPI2C Yes I2C Master and Slave LPSPI Yes LPUART Yes QSPI No RTC Yes SAI No ========== ======= ========================== ADC --- 12-Bit Successive Approximation (SAR) Analog-to-Digital Converter (ADC). No driver support (yet). CMP --- Analog Comparator. No driver support (yet). eDMA ---- Enhanced Direct Memory Access module. There is a driver that was copied from the i.MX RT port, but this was not tested on S32K1XX. EEEPROM ------- Emulated EEPROM (implemented by FlexRAM module). A basic block driver is available to read and write data. ENET ---- 10/100 Mbit/s Ethernet MAC. Only available on S32K148. Driver is available. FlexCAN ------- The S32K1XX family has up to 3x FlexCAN modules (which may not all have CAN FD support). A SocketCAN-compatible driver is available. FlexIO ------ A configurable module providing a range of functionality like emulation of a variety of serial/parallel communication protocols, flexible 16-bit timers or programmable logic blocks. No driver available. FTM --- A PWM driver based on FlexTimer (FTM) is available. GPIO ---- Pins can be configured using :c:func:`s32k1xx_pinconfig` function. Writing to pins is done by :c:func:`s32k1xx_gpiowrite` function and reading is done by :c:func:`s32k1xx_gpioread`. LPI2C ----- Low-Power Inter-Integrated Circuit (I2C) module supporting an interface to an I2C bus as master and/or as a slave. The lower-half of this driver is initialize by calling :c:func:`s32k1xx_i2cbus_initialize`. LPSPI ----- Low-Power Serial Peripheral Interface (SPI) module that supports an interface to an SPI bus as a master and/or a slave. The lower-half of this driver is initialize by calling :c:func:`s32k1xx_lpspibus_initialize`. LPUART ------ Low-Power Universal Asynchronous Receiver/Transmitter (UART) module. UART is initialized automatically during MCU boot. QSPI ---- QuadSPI memory interface for external serial flash devices. No driver implemented. RTC --- Real-Time Clock module. A basic driver has been implemented. SAI --- The Synchronous Audio Interface for digital audio over I2S (Inter-IC Sound) is only available on S32K148. No driver implemented.
