Product details
Overview
FS32K142HFT0MLLR from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with 512 KB flash, 64 KB SRAM, and support for HSRUN mode at 112 MHz. It integrates CSEc security engine, dual 12-bit ADCs (up to 32 channels), three FlexCAN modules (CAN-FD capable), and operates across -40 °C to +125 °C ambient temperature. It targets body control modules requiring functional safety up to ASIL-B.
For engineers reviewing the FS32K142HFT0MLLR datasheet, FS32K142HFT0MLLR pinout, FS32K142HFT0MLLR application, or FS32K142HFT0MLLR equivalent, this page delivers verified technical context, package mapping, real-world use scenarios, and validated alternative options - all grounded in NXP's official S32K1xx Rev. 15 datasheet and orderable part documentation.
Technical Context
The FS32K142HFT0MLLR implements a dual-core-capable architecture with Arm Cortex-M4F core (112 MHz HSRUN / 80 MHz RUN) and optional M0+ co-processor support via software configuration. It features NXP's system-level Memory Protection Unit (MPU) integrated at the AXBS-Lite crossbar switch, enabling per-master access rights for CPU, DMA, and Ethernet controllers - distinct from Arm Core MPU.
Its power management includes five low-power modes (HSRUN, RUN, STOP, VLPR, VLPS), with critical operations like CSEc cryptographic execution and EEPROM emulation restricted to RUN mode (80 MHz) due to hardware-enforced isolation - not supported in HSRUN. Clocking relies on SOSC (4–40 MHz), FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SPLL (up to 112 MHz).

Pinout & Package
FS32K142HFT0MLLR is packaged in a 64-pin LQFP (10 mm × 10 mm, 0.5 mm pitch), pin-to-pin compatible with other S32K14x devices in the same package variant. Pin functions are defined by multiplexed signal groups (e.g., PORTA–PORTE), with dedicated power/ground, clock, reset, debug, and peripheral I/O assignments per the S32K1xx Reference Manual IO Signal Description sheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Analog & digital supply inputs | Must be decoupled locally; VDD and VDDA shorted on PCB per AN5032; VREFH ≤ VDDA + 0.1 V ensures ADC accuracy. |
| RESET_B | Active-low reset input | Asynchronous, level-sensitive; internal pull-up; requires external RC filter for ECU-level reset timing compliance. |

| ADC0_SE0–ADC0_SE31 | Analog input channels | Up to 32 single-ended inputs per ADC module; 12-bit resolution, 1 Msps sampling rate; supports hardware-triggered conversions. |
| FTM0_CH0–FTM0_CH7 | FlexTimer output capture/pwm | 8-channel 16-bit timer group; supports complementary PWM with dead-time insertion for motor control gate drivers. |
Key Features
| Feature | Design Value |

FAQ
What is the maximum operating frequency of the FS32K142HFT0MLLR?
The FS32K142HFT0MLLR operates at up to 112 MHz in HSRUN mode and 80 MHz in RUN mode. HSRUN mode enables peak performance for time-critical tasks like motor control PWM generation, while RUN mode is required for CSEc security operations and EEPROM emulation - a hardware-enforced constraint documented in the S32K1xx datasheet Rev. 15.
Does the FS32K142HFT0MLLR support CAN-FD?
Yes, the FS32K142HFT0MLLR integrates three FlexCAN modules, each supporting ISO 11898-1 CAN-FD with bit-rate switching, up to 64-byte payloads, and data phase speeds up to 5 Mbps. This capability is confirmed in the S32K1xx Feature Comparison table and enabled by default in the device's silicon configuration.
What package type is used for the FS32K142HFT0MLLR?
The FS32K142HFT0MLLR uses a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch), as specified in the S32K1xx datasheet ordering information section. It is pin-to-pin compatible with other S32K14x devices in the same 64-pin LQFP variant, enabling scalable design reuse across memory and feature variants.
How does the FS32K142HFT0MLLR handle functional safety requirements?
The FS32K142HFT0MLLR meets ASIL-B requirements through integrated hardware safety mechanisms: system-level MPU enforcing memory access isolation, ECC on flash and SRAM, dual watchdogs (WDOG + EWM), CRC module, and lockstep-capable peripherals. These features are validated per ISO 26262 and documented in NXP's S32K1xx Functional Safety Manual.
Can the FS32K142HFT0MLLR execute cryptographic operations in HSRUN mode?
No - the FS32K142HFT0MLLR cannot execute CSEc cryptographic operations or EEPROM writes/erases in HSRUN mode (112 MHz). The datasheet explicitly states that doing so triggers error flags; the device must switch to RUN mode (80 MHz) to perform these functions, a hardware-enforced restriction tied to voltage/frequency safety margins.
