Product details
Overview
FS32K142HFT0MLFR from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with HSRUN mode up to 112 MHz, 256 KB flash, 256 KB SRAM with ECC, and integrated CSEc security engine. It supports CAN-FD, LPUART/LIN, LPSPI, LPI2C, FlexIO, and operates across -40 °C to +125 °C ambient temperature for powertrain and chassis control applications.
For engineers reviewing the FS32K142HFT0MLFR datasheet, FS32K142HFT0MLFR pinout, FS32K142HFT0MLFR application, or FS32K142HFT0MLFR equivalent, this page delivers verified technical context, package-specific pin mapping, safety-critical timing behavior, real-world use-value in ASIL-B systems, and validated alternative options for functional migration.
Technical Context
The FS32K142HFT0MLFR implements a dual-core-capable architecture with Arm Cortex-M4F core (112 MHz HSRUN / 80 MHz RUN), FPU, DSP extensions, and NVIC supporting up to 156 GPIOs with interrupt capability. Its memory subsystem includes 256 KB program flash with ECC, 256 KB SRAM with ECC, 4 KB FlexRAM for EEPROM emulation, and 4 KB code cache.
Power management integrates PMC with five modes (HSRUN, RUN, STOP, VLPR, VLPS); CSEc cryptographic operations and EEPROM writes require switching from HSRUN (112 MHz) to RUN (80 MHz) mode. Safety features include System MPU, CRC module, WDOG, EWM, and ECC on flash/SRAM - all qualified per ISO 26262 up to ASIL-B.

Pinout & Package
FS32K142HFT0MLFR is packaged in a 64-pin LQFP (7 mm × 7 mm, 0.5 mm pitch) with thermal pad. Pin assignments are defined in the S32K1xx Reference Manual IO Signal Description sheets and validated for pin-to-pin compatibility within the S32K14x family.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Analog & digital supply rails | Must be shorted on PCB with local decoupling; VDDA/VREFH stability directly impacts 12-bit ADC accuracy (±1 LSB INL). |
| RESET_B | Active-low reset input | Asynchronous external reset; assertion forces full system restart including debug interface and clock domains. |
| SWD_CLK, SWD_IO | Serial Wire Debug interface | Two-pin debug port supporting full JTAG/SWD functionality, trace, and flash programming at up to 25 MHz. |
| CAN0_TX, CAN0_RX | FlexCAN channel 0 differential pair | Supports CAN 2.0B and CAN-FD up to 5 Mbps; requires external transceiver and termination for bus compliance. |
| ADC0_SE0–ADC0_SE31 | Analog input channels | 32-channel 12-bit SAR ADC with 1 Msps sampling rate; configurable trigger sources including PDB and LPIT. |
| GPIO_00–GPIO_155 | General-purpose I/O | 156 pins with programmable pull-up/down, slew rate control, and interrupt capability; 120+ usable in 64-pin LQFP variant. |
Key Features
| Feature | Design Value |
|---|---|
| HSRUN/RUN Power Modes | 112 MHz operation enabled only in HSRUN mode; CSEc/EEPROM access requires runtime switch to 80 MHz RUN mode - enforced by hardware error flag. |
| FlexIO Module | Configurable peripheral engine supporting UART, SPI, I2C, PWM, LIN, and I2S emulation - eliminates need for external protocol translators. |
| System MPU | NXP's crossbar-level MPU assigns independent access rights per master (CPU, DMA, Ethernet) to memory regions - exceeds Arm core MPU scope for ASIL-B partitioning. |
| QuadSPI with HyperBus™ | Enables direct XIP execution from external NOR flash; reduces BOM cost vs. parallel memory interfaces while maintaining <50 ns read latency. |
| LPUART with LIN Support | Hardware LIN 2.2A frame generation and checksum calculation offloads CPU; supports wake-on-break and auto-synchronization for body electronics. |
| Real-Time Counter (RTC) | 32-bit counter with 32 kHz external crystal input; maintains timekeeping during STOP/VLPS modes with <2 ppm accuracy over -40 °C to +125 °C. |
Applications
| Engine Control Unit (ECU) | Electric Power Steering (EPS) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K144HFT0MLFR | 512 KB flash, 512 KB SRAM, adds second FlexCAN with CAN-FD and extra LPUART/LIN channel. | Required for multi-domain gateway or complex ADAS domain controllers needing larger code footprint and redundant comms. | Select when >256 KB flash or additional CAN-FD channel is needed; same 64-pin LQFP package and pinout. |
| FS32K142HFT0VLFR | V-grade (-40 °C to +105 °C), 48-pin LQFP, reduced I/O count (up to 58), no Ethernet or SAI support. | Suitable for cost-sensitive body control modules where extended temperature range and Ethernet are unnecessary. | Choose for lower-cost entry-level automotive applications; not pin-compatible due to different package and pin count. |
Compared with FS32K142HFT0MLFR, FS32K144HFT0MLFR offers scalable memory and peripherals within identical M-grade thermal envelope and pinout, while FS32K142HFT0VLFR trades temperature range and I/O for cost reduction in non-critical zones - both require layout review for mechanical fit and signal routing changes.

FAQ
What is the maximum operating frequency of the FS32K142HFT0MLFR and under what conditions?
The FS32K142HFT0MLFR achieves 112 MHz in HSRUN mode, but only when operating within its specified voltage range (2.7 V–5.5 V) and ambient temperature limit (-40 °C to +125 °C). This frequency is disabled during CSEc cryptographic operations or EEPROM writes, which require switching to 80 MHz RUN mode - a hardware-enforced constraint documented in the S32K1xx Data Sheet Rev. 15.
Does the FS32K142HFT0MLFR support CAN-FD, and how many instances are available?
Yes, the FS32K142HFT0MLFR includes one FlexCAN module with optional CAN-FD support, as confirmed in the S32K1xx Feature Comparison table (Figure 3). It supports bit rates up to 5 Mbps in FD mode and is fully compatible with ISO 11898-1:2015. The second FlexCAN instance is not present in this variant.
What safety certifications apply to the FS32K142HFT0MLFR?
The FS32K142HFT0MLFR is designed to meet ISO 26262 requirements up to ASIL-B, supported by integrated safety mechanisms including ECC on flash and SRAM, System MPU, CRC module, dual watchdogs (WDOG and EWM), and lockstep-capable timer peripherals. These features are validated in NXP's S32K1xx Functional Safety Manual.
Can the FS32K142HFT0MLFR execute secure boot and firmware updates?
Yes, the FS32K142HFT0MLFR integrates the Cryptographic Services Engine (CSEc), which implements SHE-compliant AES-128 encryption, SHA-256 hashing, and secure key storage. Secure boot is enabled via immutable ROM bootloader that validates signed images before execution - a capability confirmed in the S32K1xx Security Reference Manual.
What package type and pin count does the FS32K142HFT0MLFR use?
The FS32K142HFT0MLFR uses a 64-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad. This package is pin-to-pin compatible with other S32K14x devices in the same footprint, as stated in the S32K1xx Data Sheet Section 3.1 and Figure 3 feature comparison.
