Product details
Overview
FS32K144MNT0VLHR from NXP Semiconductors is an automotive-grade 32-bit Arm® Cortex-M4F microcontroller with 2 MB flash, 256 KB SRAM, and integrated CSEc security engine. It operates at up to 112 MHz in HSRUN mode (−40 °C to +105 °C), supports FlexCAN with CAN-FD, dual 12-bit ADCs (1 Msps), and IEEE-1588 Ethernet - deployed in vehicle body control modules requiring ASIL-B functional safety compliance.
For engineers reviewing the FS32K144MNT0VLHR datasheet, FS32K144MNT0VLHR pinout, FS32K144MNT0VLHR application, or FS32K144MNT0VLHR equivalent, key selection considerations include its 144-pin LQFP package, 112 MHz HSRUN/80 MHz RUN dual-mode operation, ECC-protected memory subsystem, CSEc cryptographic acceleration, and support for ISO 26262-compliant safety mechanisms including System MPU and CRC.
Technical Context
The FS32K144MNT0VLHR implements a dual-core execution environment via Arm Cortex-M4F core with FPU and DSP extensions, paired with configurable NVIC and debug infrastructure (SWD/JTAG, ITM, DWT). Its clock system integrates SPLL (up to 112 MHz), FIRC (48 MHz), SIRC (8 MHz), and LPO (128 kHz) with flexible gating across power modes.
Power management includes five operational modes (HSRUN, RUN, STOP, VLPR, VLPS), where HSRUN enables peak performance but disables CSEc and EEPROM operations - requiring explicit transition to RUN mode (80 MHz) for secure boot or data flash writes. Memory protection uses NXP's system-level MPU at the AXBS-Lite crossbar, enforcing access rights per master (core, DMA, Ethernet).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Voltage Range | 2.7 V to 5.5 V - supports direct connection to automotive battery rails with brown-out immunity down to 2.7 V in all operating modes. |

Pinout & Package
FS32K144MNT0VLHR is housed in a 144-pin LQFP package (20 mm × 20 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments follow the S32K14x standard I/O multiplexing scheme, supporting up to 156 GPIOs, multiple analog inputs, and dedicated JTAG/SWD debug pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Analog & digital supply inputs | Must be decoupled locally; VDD/VDDA differential ≤ ±0.1 V ensures ADC accuracy and I/O noise immunity. |
| PTA0–PTA31, PTB0–PTB31, etc. | GPIO banks with muxed peripherals | Each pin supports up to 4 alternate functions (e.g., LPUART0_RX, FTM0_CH0, ADC0_SE0); configured via SIM_SOPT7 and PORT registers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K144HFT0VLHR | Same core, memory, and peripherals but rated for 80 MHz max (no HSRUN mode); lacks 112 MHz capability and associated performance headroom. | Suitable for cost-sensitive gateway or body control designs where 112 MHz is unnecessary and CSEc usage is infrequent. | Select when full HSRUN performance is not required and BOM cost optimization is prioritized over future-proofing. |
| S32K146MNT0VLHR | Upgraded to 2 MB flash, 512 KB SRAM, and adds 10/100 Mbps Ethernet MAC with IEEE-1588 - identical 144-pin LQFP package and pinout. | Required for Ethernet-based domain controllers needing deterministic time synchronization and higher memory for protocol stacks. | Choose when Ethernet connectivity and expanded RAM are mandatory; maintains PCB layout compatibility with FS32K144MNT0VLHR. |
Compared with S32K144HFT0VLHR, FS32K144MNT0VLHR delivers 40% higher compute throughput in HSRUN mode for latency-critical control loops; versus S32K146MNT0VLHR, it trades Ethernet and extra RAM for lower cost and power in non-networked ECU roles.

FAQ
What is the maximum operating frequency of the FS32K144MNT0VLHR and under what conditions?
The FS32K144MNT0VLHR achieves 112 MHz in HSRUN mode at −40 °C to +105 °C ambient temperature. This frequency requires VDD ≥ 2.7 V and is disabled during CSEc execution or EEPROM write/erase operations, which mandate switching to RUN mode at 80 MHz. The device automatically asserts error flags if security or flash operations are attempted in HSRUN mode.
Does the FS32K144MNT0VLHR support CAN-FD, and how many instances are available?
Yes, the FS32K144MNT0VLHR integrates three FlexCAN modules, each supporting CAN-FD per ISO 11898-1:2015. All three instances are fully functional in the 144-pin LQFP package, with dedicated TX/RX pins mapped to PORTA and PORTB. CAN-FD operation requires external transceivers and proper termination per automotive EMC standards.
How does the CSEc engine in the FS32K144MNT0VLHR enhance security for automotive firmware updates?
The CSEc engine in the FS32K144MNT0VLHR implements SHE v1.1-compliant cryptographic primitives including AES-128/256 encryption, SHA-256 hashing, and ECDSA signature verification. It accelerates secure boot validation and authenticated firmware updates, reducing update time by >90% compared to software-only implementations while isolating keys in tamper-resistant hardware.
What power modes are supported by the FS32K144MNT0VLHR, and which are suitable for low-power vehicle sleep states?
The FS32K144MNT0VLHR supports five power modes: HSRUN, RUN, STOP, VLPR, and VLPS. For vehicle sleep states, VLPS (Very-Low-Power Stop) draws <10 µA while retaining SRAM and RTC operation, enabling wake-up via CAN, LIN, or GPIO interrupts. STOP mode offers intermediate current (~50 µA) with faster wake-up latency than VLPS.
Is the FS32K144MNT0VLHR pin-compatible with other S32K14x family members in the same package?
Yes, all S32K14x devices in the 144-pin LQFP package - including FS32K142MNT0VLHR, FS32K144MNT0VLHR, and FS32K146MNT0VLHR - are pin-to-pin compatible. Peripheral availability depends on silicon configuration, not pinout; unused functions on one variant appear as no-connects on others, allowing shared PCB designs across performance tiers.
