Product details
Overview
FS32K142HRT0MLLR from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with 512 KB flash, 64 KB SRAM, and integrated CSEc security engine. It operates at up to 80 MHz in RUN mode (−40 °C to +125 °C), supports FlexCAN with CAN-FD, LPUART/LIN, LPSPI, and LPI2C interfaces, and targets body control modules and gateway ECUs requiring ASIL-B compliance.
For engineers reviewing the FS32K142HRT0MLLR datasheet, FS32K142HRT0MLLR pinout, FS32K142HRT0MLLR application, or FS32K142HRT0MLLR equivalent, this page delivers verified technical context, package mapping, real-world use scenarios, and validated alternative options - all grounded in NXP's S32K1xx Rev. 15 datasheet and orderable part documentation.
Technical Context
The FS32K142HRT0MLLR implements a dual-core capable architecture with Arm Cortex-M4F core (80 MHz RUN / 112 MHz HSRUN), FPU, DSP extensions, and NVIC. Its memory subsystem includes 512 KB ECC-protected program flash, 64 KB SRAM with ECC, 4 KB FlexRAM for EEPROM emulation, and QuadSPI with HyperBus™ support.
Power management integrates PMC with five low-power modes (HSRUN, RUN, STOP, VLPR, VLPS); safety features include System MPU, CRC module, WDOG/EWM, and CSEc cryptographic engine - though CSEc execution requires switching from HSRUN (112 MHz) to RUN (80 MHz) mode per NXP specification.
Key Specifications

Pinout & Package
FS32K142HRT0MLLR is housed in a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch), qualified for automotive operation up to +125 °C ambient. Pin functions align with the S32K14x family's multiplexed I/O architecture, supporting up to 43 GPIOs with interrupt capability, dedicated debug (SWD/JTAG), and peripheral-specific signal routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Power supply and analog reference | Single 2.7–5.5 V rail required; VDD/VDDA must be shorted on PCB with proper decoupling - critical for ADC accuracy and system stability. |
| RESET_B | Active-low reset input | Asynchronous hardware reset with internal pull-up; compatible with external watchdog monitors (EWM) for fail-safe recovery. |
| SWD_CLK, SWD_IO | Serial Wire Debug interface | Two-pin debug port supporting full JTAG/SWD functionality - enables non-intrusive debugging, flash programming, and trace via NXP S32DS. |
| CAN0_TX, CAN0_RX | FlexCAN channel 0 differential signals | Direct connection to external CAN transceiver; supports CAN-FD bit rates up to 5 Mbps - essential for high-bandwidth gateway nodes. |
| LPUART0_RX, LPUART0_TX | Low-power UART channel 0 | Hardware UART with DMA and wake-from-stop capability - ideal for LIN slave node communication and diagnostic interfaces. |
| ADC0_SE0–ADC0_SE15 | Analog input channels | 16 configurable single-ended inputs shared across 12-bit ADC - supports simultaneous sampling of battery voltage, thermistors, and potentiometers. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Ready Architecture | System MPU, ECC on flash/SRAM, CRC module, and dual watchdog (WDOG + EWM) enable ISO 26262-compliant software partitioning and fault containment. |
| Flexible Low-Power Operation | Five power modes (VLPR/VLPS/STOP/RUN/HSRUN) with clock gating per peripheral - reduces active current to <100 µA in VLPS while retaining RAM and RTC state. |
| Secure Boot & Firmware Updates | CSEc engine performs authenticated boot, AES-128 encryption, and SHA-256 hashing - eliminates need for external secure element in cost-sensitive ECUs. |
| Peripheral Multiplexing | TRGMUX and IO MUX allow dynamic reassignment of LPUART/LPSPI/LPI2C signals to multiple pin groups - simplifies layout and enables reuse across variants. |
| Robust Analog Integration | 12-bit ADC with hardware averaging, calibration registers, and window compare - improves measurement repeatability in noisy automotive environments. |
| Time-Sensitive Execution | LPIT (4-channel 32-bit timer), LPTMR, and PDB support precise PWM generation, periodic wakeups, and synchronized ADC sampling - critical for motor control timing. |
