Product details
Overview
FS32K142HFT0MLHT from NXP Semiconductors is an automotive-grade Arm® Cortex-M4F microcontroller designed for real-time control in engine management, battery monitoring, and chassis electronics. 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.
For engineers reviewing the FS32K142HFT0MLHT datasheet, FS32K142HFT0MLHT pinout, FS32K142HFT0MLHT application, or FS32K142HFT0MLHT equivalent, key selection criteria include ASIL-B capable safety architecture, CSEc cryptographic engine, FlexCAN with CAN-FD support, dual 12-bit ADCs (1 Msps), and HSRUN/RUN/STOP/VLPR/VLPS power modes - all validated for automotive ECU designs requiring functional safety compliance.
Technical Context
The FS32K142HFT0MLHT implements an Arm Cortex-M4F core with single-precision FPU and DSP extensions, executing at up to 80 MHz in RUN mode (HSRUN mode disabled per M-grade thermal limits). Its memory subsystem includes ECC-protected 256 KB program flash, 256 KB SRAM, and 4 KB FlexRAM usable as EEPROM emulation or SRAM.
Peripheral integration centers on safety-critical I/O: two 12-bit ADCs (32-channel total), three FlexCAN modules (one with CAN-FD), three LPUART/LIN interfaces, two LPI2C, three LPSPI, eight FlexTimer modules (64 PWM/IC/OC channels), and CSEc security engine supporting SHE-compliant cryptographic operations - all accessible via AXBS-Lite crossbar and eDMA with DMAMUX routing.
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 control and sensor fusion. |
| Max Clock Frequency | 80 MHz in RUN mode - thermal limit for M-grade (-40 °C to +125 °C) operation; HSRUN (112 MHz) prohibited per datasheet note. |
| Flash Memory | 256 KB with ECC - provides robust code storage with error detection/correction for ASIL-B compliant applications. |
| SRAM | 256 KB with ECC - supports large real-time buffers and safety-critical data structures with integrity protection. |

| Security Engine | Cryptographic Services Engine (CSEc) compliant with SHE specification - provides hardware-accelerated AES, SHA, RNG, and secure boot for ECU authentication and firmware integrity. |
| Power Modes | HSRUN, RUN, STOP, VLPR, VLPS - enables dynamic power scaling across vehicle states (e.g., RUN during active driving, VLPS during sleep). |
Pinout & Package
FS32K142HFT0MLHT is housed in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments follow S32K14x family standard I/O multiplexing, supporting configurable GPIO, analog inputs, CAN transceivers, UART/SPI/I2C peripherals, and dedicated debug (SWD/JTAG) signals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Analog & digital supply rails | Must be decoupled individually; VDDA and VREFH require low-noise filtering for ADC accuracy per AN5032. |
| PTA0–PTA31, PTB0–PTB31, etc. | Multi-function GPIO ports | Configurable as digital I/O, ADC inputs, FlexCAN TX/RX, LPUART, LPSPI, or FlexTimer channels - routed via TRGMUX and IO_MUX. |
| CAN0_TX / CAN0_RX | FlexCAN0 differential interface | Requires external CAN transceiver; supports ISO 11898-1 physical layer and CAN-FD protocol up to 5 Mbps. |
| SWD_DIO / SWD_CLK | Serial Wire Debug interface | Enables non-intrusive debugging, flash programming, and trace via SWJ-DP; compatible with NXP S32DS and third-party tools. |
| RESET_b | Active-low reset input | Asynchronous reset signal; internal pull-up; must meet tRST timing (≥ 100 ns pulse width) for reliable initialization. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Capable Safety Architecture | Integrated System MPU, ECC on flash/SRAM, CRC module, WDOG/EWM, and lockstep-capable peripherals - satisfies ISO 26262 requirements for automotive control units. |
| FlexCAN with CAN-FD Support | One of three FlexCAN modules supports CAN-FD (up to 5 Mbps data phase) - enables higher bandwidth firmware updates and diagnostic messaging without bus congestion. |
| Dual High-Speed ADCs | Two independent 12-bit SAR ADCs, each sampling at 1 Msps with up to 32 channels - allows concurrent acquisition of engine knock, throttle position, and coolant temperature with <1 µs inter-channel skew. |
| CSEc Security Engine | Hardware SHE-compliant crypto engine with AES-128/256, SHA-256, RNG, and secure key storage - enables secure boot, firmware signing, and OTA update authentication without CPU overhead. |
| Low-Power Operation | Five power modes (RUN, STOP, VLPR, VLPS, HSRUN) with clock gating and peripheral isolation - reduces quiescent current to <10 µA in VLPS mode for always-on ECU functions. |
| FlexTimer & PDB | Eight 16-bit FlexTimer modules (64 channels) + two Programmable Delay Blocks - supports precise PWM generation for fuel injection, ignition timing, and motor phase control with sub-microsecond jitter. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K144HFT0MLHT | 512 KB flash, 512 KB SRAM, additional FlexCAN and LPSPI modules - same M-grade temp range and 100-pin LQFP package. | Supports larger firmware images and more complex sensor fusion algorithms; suitable for next-gen ECU platforms requiring extended memory headroom. | Select when >256 KB flash is required for AUTOSAR OS, diagnostics, or OTA update staging; pin-compatible but requires PCB layout review for unused pins. |
| S32K142HFT0VLHT | V-grade (-40 °C to +105 °C), identical memory/peripheral set, same 100-pin LQFP package - lacks M-grade high-temp qualification. | Targeted at non-powertrain applications (e.g., body control, lighting) where extended temperature range is not mandated. | Choose for cost-sensitive Tier 2 modules where 125 °C ambient rating is unnecessary; full software compatibility with FS32K142HFT0MLHT. |
Compared with FS32K142HFT0MLHT, S32K144HFT0MLHT offers double memory capacity for AUTOSAR-compliant stacks, while S32K142HFT0VLHT reduces thermal qualification cost for non-critical zones - both retain identical peripheral sets and safety architecture, enabling scalable platform design.

FAQ
What is the maximum operating frequency of the FS32K142HFT0MLHT?
The FS32K142HFT0MLHT operates at up to 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 FS32K142HFT0MLHT to 80 MHz per datasheet thermal specifications. Attempting HSRUN mode triggers error flags during CSEc or EEPROM operations, requiring mode switch to RUN.
Does the FS32K142HFT0MLHT support CAN-FD?
Yes, the FS32K142HFT0MLHT includes three FlexCAN modules, with one supporting CAN-FD (ISO 11898-1) at data rates up to 5 Mbps. This capability is confirmed in the S32K1xx feature comparison table and applies directly to the K142 variant in 100-pin LQFP packages. External CAN transceivers are required for physical layer implementation.
What safety certifications apply to the FS32K142HFT0MLHT?
The FS32K142HFT0MLHT is designed to support ASIL-B compliance per ISO 26262, featuring integrated System MPU, ECC on flash and SRAM, CRC module, dual watchdogs (WDOG and EWM), and lockstep-capable peripherals. NXP provides safety documentation including FMEDA reports and safety manuals - all applicable to FS32K142HFT0MLHT as part of the qualified S32K14x series.
How much SRAM and flash memory does the FS32K142HFT0MLHT have?
The FS32K142HFT0MLHT integrates 256 KB of program flash memory with ECC protection and 256 KB of SRAM also protected by ECC. Additionally, it includes 4 KB of FlexRAM configurable as SRAM or EEPROM emulation, and 64 KB of FlexNVM for data flash - though FlexNVM size varies by orderable part; FS32K142HFT0MLHT uses the base 256 KB flash configuration.
Is the FS32K142HFT0MLHT pin-compatible with other S32K14x devices?
Yes, all S32K14x devices sharing the same package (e.g., 100-pin LQFP) are pin-to-pin compatible, including FS32K142HFT0MLHT, FS32K144HFT0MLHT, and FS32K146HFT0MLHT. This enables hardware reuse across product variants - however, unused pins in lower-memory variants must be handled per NXP's hardware design guidelines to avoid floating inputs or EMC issues.
