Product details
Overview
FS32K146HFT0MLQR from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with 2 MB flash, 256 KB SRAM (both with ECC), 112 MHz HSRUN/80 MHz RUN operation, -40 °C to +125 °C ambient rating, and integrated CSEc security engine. It serves as the main application controller in body control modules, battery management systems, and chassis domain controllers requiring ASIL-B functional safety compliance.
For engineers reviewing the FS32K146HFT0MLQR datasheet, FS32K146HFT0MLQR pinout, FS32K146HFT0MLQR application, or FS32K146HFT0MLQR equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use-value analysis for automotive ECU design, and validated alternative part comparisons - all grounded in NXP's official S32K1xx Rev. 15 datasheet and orderable part number list.
Technical Context
The FS32K146HFT0MLQR 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. Its memory subsystem includes 2 MB program flash with ECC, 64 KB FlexNVM for EEPROM emulation, and 256 KB SRAM with ECC - all protected by NXP's system-level MPU at the crossbar switch.
It integrates three FlexCAN modules (all supporting CAN-FD per ISO 11898-1), up to eight 16-bit FlexTimers (64 total PWM/IC/OC channels), and low-power peripherals including LPUART, LPSPI, LPI2C, and LPIT - all accessible in VLPR/VLPS stop modes. Security execution requires mode switching from HSRUN to RUN due to hardware-enforced isolation of CSEc and EEPROM operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Voltage Range | 2.7 V to 5.5 V - supports direct connection to automotive 12 V battery via single-stage regulator; no external level-shifting needed for 3.3 V or 5 V I/O domains. |
| CPU Core | Arm Cortex-M4F with FPU - enables real-time motor control algorithms, sensor fusion, and floating-point math without external coprocessor. |
| Max Clock Frequency | 112 MHz (HSRUN), 80 MHz (RUN) - HSRUN enables peak compute for active safety tasks; RUN mode required for CSEc security operations and EEPROM writes. |
| Flash / SRAM | 2 MB flash + 256 KB SRAM, both with ECC - meets ASIL-B requirements for memory integrity in safety-critical automotive applications. |
| Temperature Grade | -40 °C to +125 °C (M-grade) - qualified for under-hood deployment in engine control, transmission, and ADAS sensor nodes. |
| Security Engine | Cryptographic Services Engine (CSEc) - provides SHE-compliant AES-128, SHA-256, RNG, and secure boot key management without software overhead. |
| FlexCAN Channels | 3 × CAN-FD modules - supports high-bandwidth vehicle networking with data rates up to 5 Mbps and payload expansion beyond classic CAN. |
| I/O Count | Up to 156 GPIOs - enables direct interface to sensors, actuators, and LIN transceivers in consolidated ECU designs. |
Pinout & Package
FS32K146HFT0MLQR is packaged in a 100-pin LQFP (Lead-Free, RoHS-compliant) with 0.5 mm pitch and exposed thermal pad. This package supports full peripheral availability including all three FlexCAN interfaces, dual ADC modules, Ethernet MAC, and SAI audio interfaces - subject to pin multiplexing constraints defined in the S32K1xx Reference Manual.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Analog & digital power supply inputs | Must be decoupled individually; VDDA and VREFH require low-noise filtering for 12-bit ADC accuracy (±1 LSB INL). |
| PTA0–PTA31, PTB0–PTB31, etc. | GPIO bank terminals | Configurable as digital I/O, ADC input, FlexCAN TX/RX, LPUART, or FlexTimer channels - mapped per pinmux sheet in RM. |
| CAN0_TX / CAN0_RX | FlexCAN Channel 0 differential pair | Requires external 120 Ω termination; supports CAN-FD bit rates up to 5 Mbps with flexible data phase timing. |
| ENET0_RMII_RXD0–RXD1 | Ethernet physical layer interface | Direct RMII connection to PHY; supports IEEE 1588 timestamping for time-synchronized vehicle networks. |
| JTAG_TMS / SWD_DIO | Debug interface signals | Shared with GPIO; SWD mode preferred for production programming and boundary scan testing per JTAG chain requirements. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Compliant Architecture | System MPU, ECC on flash/SRAM, CRC module, and dual-watchdog (WDOG + EWM) enable ISO 26262-compliant safety mechanisms without external components. |
| Flexible Power Modes | Five distinct modes (HSRUN/RUN/STOP/VLPR/VLPS) allow dynamic trade-off between performance (112 MHz) and ultra-low leakage (<1 µA in VLPS) for battery-powered ECUs. |
| FlexIO Subsystem | Configurable logic block supporting UART, SPI, I2C, I2S, LIN, and custom protocols - eliminates need for external protocol bridge ICs in mixed-interface gateways. |
| QuadSPI with HyperBus™ | Enables direct XIP execution from external NOR flash or PSRAM, reducing BOM cost and PCB footprint versus parallel memory interfaces. |
| Real-Time Counter (RTC) | 32-bit counter with 32 kHz external clock input and tamper-detection capability - provides secure, battery-backed timekeeping for event logging and firmware update scheduling. |
| ADC Performance | Two 12-bit SAR ADCs (1 Msps each, 32-channel total) with hardware trigger synchronization - supports simultaneous sampling across multiple current/voltage sensors in motor control loops. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K144HFT0VLQR | 1 MB flash, 192 KB SRAM, same 100-pin LQFP package, V-grade (-40 °C to +105 °C) | Lower memory capacity and reduced temperature range; lacks one FlexCAN channel and one ADC module | Select when cost-sensitive body electronics applications do not require full 2 MB flash or 125 °C operation. |
| S32K148HFT0MLQR | 2 MB flash, 384 KB SRAM, adds 10/100 Mbps Ethernet MAC and dual SAI audio interfaces; same M-grade temp range | Supports time-sensitive networking (TSN) and audio streaming - required for zonal architecture gateways and infotainment-adjacent control units | Choose when Ethernet connectivity or multi-channel audio I/O is mandatory; otherwise FS32K146HFT0MLQR offers optimal balance of features and cost. |
Compared with S32K144HFT0VLQR, FS32K146HFT0MLQR delivers 100% more flash and extended temperature capability for under-hood deployment; versus S32K148HFT0MLQR, it removes Ethernet and SAI to reduce cost and power while retaining identical CAN-FD, timer, and safety feature sets for chassis and powertrain control.

FAQ
What is the maximum operating frequency of the FS32K146HFT0MLQR in HSRUN mode?
The FS32K146HFT0MLQR operates at up to 112 MHz in HSRUN mode, delivering 1.25 Dhrystone MIPS per MHz. This mode is optimized for peak computational throughput in active safety and motor control applications. However, CSEc security operations and EEPROM writes must be executed in RUN mode (80 MHz) due to hardware-enforced isolation - a constraint explicitly documented in the S32K1xx datasheet Rev. 15.
Does the FS32K146HFT0MLQR support CAN-FD, and how many interfaces are available?
Yes, the FS32K146HFT0MLQR integrates three independent FlexCAN modules, all supporting CAN-FD per ISO 11898-1 with data rates up to 5 Mbps. Each module supports programmable bit timing, message buffering, and hardware acceptance filtering - enabling robust vehicle networking in domain controllers and gateway ECUs without external CAN transceivers beyond physical layer drivers.
What package type and pin count does the FS32K146HFT0MLQR use?
The FS32K146HFT0MLQR uses a 100-pin LQFP package with 0.5 mm pitch and RoHS-compliant lead-free finish. This package supports full peripheral access including all three FlexCAN interfaces, dual 12-bit ADCs, Ethernet MAC, and SAI audio interfaces - subject to pin multiplexing rules defined in the S32K1xx Reference Manual IO Signal Description sheet.
How does the FS32K146HFT0MLQR meet automotive functional safety requirements?
The FS32K146HFT0MLQR achieves ASIL-B compliance through integrated hardware safety mechanisms: ECC on 2 MB flash and 256 KB SRAM, system-level MPU enforcing memory partitioning at the crossbar switch, dual watchdogs (WDOG + EWM), CRC acceleration unit, and lockstep-capable debug infrastructure. These features are validated per ISO 26262 and documented in NXP's S32K1xx Functional Safety Manual.
Is the FS32K146HFT0MLQR pin-compatible with other S32K1xx devices in the same package?
Yes - all S32K1xx devices sharing the same package (e.g., 100-pin LQFP) are pin-to-pin compatible per NXP's official documentation. This allows scalable migration between variants like S32K144HFT0VLQR and S32K148HFT0MLQR without PCB redesign, provided peripheral usage aligns with the target device's feature set and pinmux configuration.
