|
===========
|
|
|
|
The `S32K1XX series <https://www.nxp.com/products/processors-and-microcontrollers/s32-automotive-platform/s32k-general-purpose-mcus/s32k1-microcontrollers-for-general-purpose:S32K1>`_ 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.

|
|
|
|
|
|
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.
|
|
|
|
EEPROM
|
|
-------
|
|
|
|
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

|
|
|
|
LPSPI
|
|
-----
|
|
|
|
Low-Power Serial Peripheral Interface (SPI) module that supports an interface to an SPI bus as a master

|
|
|
|
LPUART
|
|
