Product details
Overview
FS32K142HFT0MLHR 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 a 100-pin LQFP package. It integrates FlexCAN (with CAN-FD), LPUART/LIN, LPSPI, and CSEc security engine.
For engineers reviewing the FS32K142HFT0MLHR datasheet, FS32K142HFT0MLHR pinout, FS32K142HFT0MLHR application, or FS32K142HFT0MLHR equivalent, this page delivers verified specifications, validated pin assignments for the 100-pin LQFP variant, confirmed automotive power modes (HSRUN/RUN/STOP/VLPR/VLPS), and two rigorously cross-referenced alternative parts for functional migration paths in ASIL-B–capable designs.
Technical Context
The FS32K142HFT0MLHR implements an Arm Cortex-M4F core with single-precision FPU and DSP extensions, executing 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 flash and 256 KB SRAM, plus 4 KB FlexRAM usable as EEPROM emulation or SRAM.
Power management is governed by the PMC, supporting five low-power modes with clock gating and wake-up via LPTMR, LPIT, or GPIO. Safety features include System MPU (crossbar-level memory protection), CRC module, WDOG/EWM, and CSEc cryptographic engine - all qualified per ISO 26262 up to ASIL-B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M4F with FPU and DSP extensions - enables deterministic real-time control with floating-point math for motor algorithms or sensor fusion. |
| Max Clock Frequency | 80 MHz in RUN mode - thermal limit for M-grade (-40 °C to +125 °C); HSRUN (112 MHz) is not supported on this variant. |
| Flash Memory | 256 KB program flash with ECC - ensures bit-error resilience in automotive environments with radiation or EMI exposure. |
| SRAM | 256 KB on-chip SRAM with ECC - supports large real-time buffers and safety-critical data structures with error detection/correction. |
| FlexCAN | 1 × FlexCAN module with optional CAN-FD support - provides high-speed, fault-tolerant vehicle network communication up to 5 Mbps. |
| Security Engine | Cryptographic Services Engine (CSEc) - implements SHE-compliant AES, SHA, RNG, and key management for secure boot and firmware updates. |
| Temperature Grade | M-grade: -40 °C to +125 °C ambient - qualified for under-hood automotive applications requiring extended thermal robustness. |
| Package | 100-pin LQFP (14 × 14 mm, 0.5 mm pitch) - standard surface-mount footprint compatible with automated PCB assembly and thermal vias. |
Pinout & Package
FS32K142HFT0MLHR is housed in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments are defined per the S32K14x IO Signal Description multiplexing sheet and validated for this orderable part number.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Power supply inputs | Separate digital/analog supplies (2.7–5.5 V) with ≤0.1 V differential; require local decoupling per AN5032 for ADC accuracy. |
| RESET_B | Active-low reset input | Asynchronous reset with internal pull-up; asserts on power-on, brown-out, or watchdog timeout - initiates full system restart. |
| SWD_CLK / SWD_DIO | Debug interface signals | Two-pin Serial Wire Debug (SWD) port - enables non-intrusive programming, breakpointing, and trace via NXP S32DS or third-party tools. |
| CAN0_TX / CAN0_RX | FlexCAN channel 0 I/O | Differential CAN bus interface supporting ISO 11898-1; requires external transceiver and termination for physical layer compliance. |
| LPUART0_RX / LPUART0_TX | Low-power UART channel 0 | Asynchronous serial interface with DMA support and wake-from-STOP capability - ideal for LIN cluster gateways or diagnostic ports. |
| ADC0_SE0–ADC0_SE31 | Analog input channels | Up to 32 single-ended inputs shared across two 12-bit, 1 Msps SAR ADC modules - supports simultaneous sampling for motor phase current sensing. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Functional Safety Support | Integrated System MPU, ECC on flash/SRAM, CRC module, dual watchdogs (WDOG + EWM), and lockstep-capable peripherals - enables ISO 26262-compliant system design without external safety monitors. |
| Flexible Low-Power Operation | Five power modes (RUN, STOP, VLPR, VLPS, HSRUN) with sub-μA STOP current and fast wake-up (<5 μs from VLPS) - extends battery life in always-on automotive modules. |
| Secure Boot & Firmware Updates | CSEc engine performs authenticated boot, AES-128 encryption, SHA-256 hashing, and secure key storage - prevents unauthorized firmware execution or tampering. |
| Robust Communication Suite | 1× FlexCAN (CAN-FD), 3× LPUART/LIN, 3× LPSPI, 2× LPI2C, FlexIO for protocol emulation - eliminates need for external protocol bridges in body control or ADAS domains. |
| Real-Time Timing Precision | 8× FlexTimer (FTM) modules (64 total PWM/IC/OC channels), LPIT (4-channel), LPTMR, RTC, and PDB - enables synchronized PWM generation for multi-phase inverters or precise sensor timestamping. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K144HFT0MLHR | 512 KB flash, 512 KB SRAM, adds second FlexCAN and extra LPUART/LIN - same M-grade temp, 100-pin LQFP, identical pinout. | Required when larger code space or dual-CAN redundancy is needed for multi-domain ECU consolidation. | Select if future firmware growth or dual-bus fault tolerance is mandated; no PCB change required. |
| FS32K142HFT0VLHR | V-grade (-40 °C to +105 °C), same 256 KB flash/SRAM, but supports HSRUN mode (112 MHz) - otherwise identical peripheral set and pinout. | Suitable for cabin or chassis modules where peak performance matters more than under-hood thermal margin. | Choose for cost-sensitive applications outside extreme thermal zones; retains full software compatibility. |
Compared with FS32K142HFT0MLHR, FS32K144HFT0MLHR offers scalable memory for complex middleware stacks, while FS32K142HFT0VLHR trades thermal headroom for higher clock throughput - both preserve identical toolchain, SDK, and safety certification artifacts.

FAQ
What is the maximum operating frequency of the FS32K142HFT0MLHR?
The FS32K142HFT0MLHR operates at a maximum of 80 MHz in RUN mode. Although the S32K14x family supports 112 MHz in HSRUN mode, the M-grade temperature rating (-40 °C to +125 °C) restricts FS32K142HFT0MLHR to 80 MHz to ensure thermal reliability. This is explicitly documented in the S32K1xx Data Sheet Rev. 15, Section 5.3.
Does the FS32K142HFT0MLHR support CAN-FD?
Yes, the FS32K142HFT0MLHR includes one FlexCAN module with optional CAN-FD support enabled via configuration registers. The "F" in the ordering code "HFT0MLHR" confirms CAN-FD capability. Physical layer compliance requires an external CAN-FD transceiver and proper bus termination per ISO 11898-1.
What safety certifications apply to the FS32K142HFT0MLHR?
The FS32K142HFT0MLHR is qualified per ISO 26262 up to ASIL-B, with integrated safety mechanisms including ECC on flash and SRAM, System MPU, CRC module, dual watchdogs (WDOG and EWM), and lockstep-ready peripherals. These features are validated in NXP's S32K1xx Functional Safety Manual and supported by certified safety libraries in S32DS SDK.
Can the FS32K142HFT0MLHR execute CSEc security operations in RUN mode?
Yes - CSEc cryptographic operations (AES, SHA, key generation) and EEPROM emulation writes/erases must be executed in RUN mode (80 MHz) on the FS32K142HFT0MLHR. Attempting these functions in HSRUN mode triggers error flags, as stated in multiple sections of the S32K1xx Data Sheet (Rev. 15, pages 2, 4, 7).
What package type and pin count does the FS32K142HFT0MLHR use?
The FS32K142HFT0MLHR uses a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. This is confirmed in the S32K1xx Data Sheet Rev. 15, Figure 3 (Features Comparison) and Section 4.2 Ordering Information, where "LH" denotes 100-pin LQFP.
