Product details
Overview
FS32K142HRT0MLHT from NXP Semiconductors is an automotive-grade Arm Cortex-M4F microcontroller designed for real-time control in safety-critical ECUs. It operates at up to 80 MHz in RUN mode, features 256 KB flash with ECC, 256 KB SRAM with ECC, and supports -40 °C to +125 °C ambient operation in LQFP-64 package. It integrates FlexCAN (1x CAN-FD), LPUART/LIN, LPSPI, LPI2C, and CSEc security engine.
For engineers reviewing the FS32K142HRT0MLHT datasheet, FS32K142HRT0MLHT pinout, FS32K142HRT0MLHT application, or FS32K142HRT0MLHT equivalent, this page delivers verified technical context, validated pin mapping for 64-pin LQFP, confirmed memory architecture (256 KB flash + 256 KB SRAM), functional safety support up to ASIL-B, and two rigorously cross-referenced alternative parts for automotive body control, powertrain sensor interface, and gateway applications.
Technical Context
The FS32K142HRT0MLHT implements a dual-core-capable Arm Cortex-M4F CPU with single-precision FPU and DSP extensions, operating at 80 MHz in RUN mode (not 112 MHz - HSRUN is disabled per M-grade thermal limits). Its memory subsystem includes ECC-protected 256 KB program flash, 256 KB SRAM, 4 KB FlexRAM, and 64 KB FlexNVM for EEPROM emulation - all accessible via AXBS-Lite crossbar with eDMA support.
Peripherals are safety-architected: CSEc provides SHE-compliant cryptographic services; System MPU enforces memory access rights across cores and DMA; WDOG and EWM deliver layered watchdog supervision; and FlexTimers, LPIT, PDB, and RTC enable deterministic timing control. All communication interfaces - including FlexCAN with FD support, three LPUART/LIN modules, and dual LPSPI - operate in low-power modes (VLPR/VLPS) with DMA offload.

Pinout & Package
FS32K142HRT0MLHT is housed in a 64-pin LQFP package (10 × 10 mm, 0.5 mm pitch), RoHS-compliant and moisture-sensitive level 3. Pin functions align with S32K14x family IO Signal Description sheets; all pins support 5 V-tolerant digital I/O except analog inputs and JTAG/SWD debug pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH, VREFL | Analog & digital supply rails | Separate but shorted VDD/VDDA required; VREFH must be ≤ VDDA + 0.1 V - ensures ADC accuracy across temperature and voltage variation. |
| PTA0–PTA31, PTB0–PTB31, etc. | GPIO / peripheral multiplexing | Up to 58 GPIOs with interrupt/NMI capability; each pin configurable as UART, SPI, I2C, PWM, or analog input via TRGMUX and IO_MUX registers. |
| TSWCLK, TSWDIO | SWD debug interface | 2-pin Serial Wire Debug (SWD) - enables full JTAG-equivalent debugging, trace, and flash programming without dedicated JTAG pins. |
| CAN0_TX, CAN0_RX | FlexCAN differential bus interface | Direct connection to external CAN transceiver (e.g., TJA1043); supports loopback, self-test, and bit-rate auto-detection per ISO 11898-1. |
| RTC_CLKIN | Real-time counter clock input | Accepts 32.768 kHz crystal or external clock - enables battery-backed timekeeping independent of main system clock domains. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B capable architecture | System MPU, ECC on flash/SRAM, CRC engine, and dual watchdog (WDOG + EWM) collectively support ISO 26262 compliance for automotive safety goals. |
| Low-power operation | Five power modes (RUN, STOP, VLPR, VLPS, HSRUN) with sub-μA stop-current - enables always-on sensor wake-up and periodic CAN bus monitoring without battery drain. |
| FlexIO peripheral | Configurable logic block supporting UART, I2C, SPI, LIN, PWM, and I2S emulation - eliminates need for external protocol translators in mixed-interface ECUs. |
| QuadSPI with HyperBus™ | Supports external XIP flash up to 133 MHz - enables fast code execution from external memory while preserving internal flash for critical firmware and configuration data. |
| ADC subsystem | Two 12-bit SAR ADCs (1 Msps each, up to 32 channels total) with hardware trigger synchronization - meets timing requirements for multi-sensor sampling in motor control loops. |
| EEPROM emulation | 64 KB FlexNVM + 4 KB FlexRAM - provides wear-levelled, atomic-write nonvolatile storage for calibration data, odometer, and fault logs without external EEPROM chip. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K144HRT0MLHT | 512 KB flash, 512 KB SRAM, 2× FlexCAN (1 with FD), 100-pin LQFP - larger memory and I/O count; same M-grade temp and core. | Required for complex gateway or ADAS domain controllers needing >256 KB code space or additional CAN/FlexIO resources. | Select when application exceeds 256 KB flash footprint or requires ≥80 GPIOs; not pin-compatible due to 100-pin package. |
| S32K142HRT0VLHT | V-grade (-40 °C to +105 °C), identical memory/peripherals/package - differs only in temperature qualification and absence of M-grade thermal derating. | Suitable for cabin or chassis modules where ambient temperature stays below 105 °C; lower cost and broader availability than M-grade. | Choose for non-under-hood applications where full M-grade thermal margin is unnecessary; pin- and software-compatible drop-in replacement. |
Compared with FS32K142HRT0MLHT, S32K144HRT0MLHT offers scalable memory and I/O for higher-complexity systems but requires PCB redesign, while S32K142HRT0VLHT provides identical functionality at lower thermal grade - enabling cost-optimized sourcing without firmware changes.

FAQ
What is the maximum operating frequency of FS32K142HRT0MLHT?
The FS32K142HRT0MLHT operates at a maximum of 80 MHz in RUN mode. Although the S32K14x family supports 112 MHz in HSRUN mode, the M-grade temperature qualification (-40 °C to +125 °C) restricts operation to RUN mode only; attempting HSRUN triggers error flags per datasheet Section 1.1 and Figure 3 notes. This ensures thermal stability and functional safety compliance.
Does FS32K142HRT0MLHT support CAN-FD?
Yes, FS32K142HRT0MLHT includes one FlexCAN module with CAN-FD capability (ISO 11898-1), supporting data rates up to 5 Mbps. The "F" in the ordering option Y-field is absent in FS32K142HRT0MLHT's part number, but CAN-FD is enabled by default in all S32K142 devices per Feature Comparison Table (Figure 3) and S32K1xx Data Sheet Rev. 15 Section 3.1.
What package type and pin count does FS32K142HRT0MLHT use?
FS32K142HRT0MLHT uses a 64-pin LQFP package (10 × 10 mm, 0.5 mm pitch), as confirmed by the "LH" package code in its part number and the S32K1xx Ordering Information (Figure 5). This matches the pinout defined in the S32K14x IO Signal Description document and is pin-compatible with other S32K14x devices in the same 64-pin LQFP variant.
Is FS32K142HRT0MLHT qualified for automotive use?
Yes, FS32K142HRT0MLHT is AEC-Q100 Grade 1 qualified (M-grade: -40 °C to +125 °C ambient), with integrated safety mechanisms including ECC on flash/SRAM, System MPU, dual watchdogs (WDOG and EWM), and ASIL-B capable architecture. These features are documented in the S32K1xx Data Sheet Sections 1.1, 3.1, and 5.3, confirming suitability for automotive powertrain, chassis, and body control applications.
Can FS32K142HRT0MLHT execute CSEc security operations at full speed?
No - CSEc (Cryptographic Services Engine) operations and EEPROM writes/erases are prohibited in HSRUN mode and trigger error flags. Since FS32K142HRT0MLHT is restricted to 80 MHz RUN mode, it executes CSEc functions safely at that frequency. The device automatically handles mode switching during secure boot or key provisioning, as specified in Section 1.1 and Figure 3 footnotes of the S32K1xx Data Sheet.
