Product details
Overview
FX32K144HAT0MLHR 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, and integrated CSEc security engine. It features dual 12-bit ADCs (32-channel total), three FlexCAN modules (CAN-FD capable), and operates across -40 °C to +125 °C for engine control and body electronics applications.
For engineers reviewing the FX32K144HAT0MLHR datasheet, FX32K144HAT0MLHR pinout, FX32K144HAT0MLHR application, or FX32K144HAT0MLHR equivalent, this page delivers verified technical context, package-specific pin mapping, safety-critical power mode behavior, real-world automotive use cases, and validated alternative parts - all grounded in NXP's S32K1xx Rev. 15 datasheet and orderable part number specifications.
Technical Context
The FX32K144HAT0MLHR implements a dual-core architecture with Arm Cortex-M4F as primary execution core (112 MHz HSRUN, 80 MHz RUN) and optional M0+ co-processor support, backed by a crossbar switch (AXBS-Lite) enabling concurrent bus access for eDMA, Ethernet, and peripherals. Its memory subsystem includes 2 MB program flash with ECC, 64 KB FlexNVM with EEPROM emulation, and 256 KB SRAM with ECC - all protected by NXP's system MPU at the crossbar level.
Power management is governed by the PMC with five modes: HSRUN (112 MHz), RUN (80 MHz), STOP, VLPR, and VLPS. Critical operations like CSEc cryptographic execution or EEPROM write/erase are explicitly restricted to RUN mode (80 MHz); attempting them in HSRUN triggers error flags per datasheet Section 1.1 and Figure 3 footnotes.
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 transient tolerance up to 5.8 V for ≤60 s lifetime. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood engine control unit (ECU) placement per M-grade thermal specs (TJ ≤135 °C at TA = 125 °C). |
| CPU Core | Arm Cortex-M4F with FPU and DSP extensions - delivers 1.25 Dhrystone MIPS/MHz; enables real-time motor control and sensor fusion algorithms. |
| Flash / SRAM | 2 MB program flash + 256 KB SRAM, both with ECC - ensures ASIL-B compliance via single-bit error correction and double-bit error detection in safety-critical code/data storage. |
| FlexCAN Channels | 3 × FlexCAN modules, CAN-FD capable - provides redundant high-speed vehicle network interfaces for powertrain and chassis domains. |
| ADC System | 2 × 12-bit SAR ADCs, up to 32 channels total, 1 Msps - supports simultaneous sampling of multiple engine sensors (MAP, TPS, O2) with hardware trigger synchronization. |
| Security Engine | Cryptographic Services Engine (CSEc) - implements SHE-compliant AES-128, SHA-256, RNG, and secure boot; requires RUN mode (80 MHz) for key provisioning. |
Pinout & Package
FX32K144HAT0MLHR is supplied in a 144-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignment follows the S32K144W series pinout documented in NXP's S32K1xx Reference Manual IO Signal Description sheets.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Power supply inputs | Must be shorted on PCB with local decoupling; VDDA/VREFH define ADC accuracy - deviation >±0.1 V degrades linearity and offset performance. |
| RESET_b | Active-low reset input | Asynchronous, Schmitt-triggered; asserts internal POR and initiates boot sequence from flash or ROM bootloader depending on BOOTCFG pins. |
| SWD_CLK / SWD_DIO | Serial Wire Debug interface | Two-pin debug port supporting full JTAG/SWD functionality - enables non-intrusive trace, breakpoint, and memory inspection during ECU calibration. |
| CAN0_TX / CAN0_RX | FlexCAN Channel 0 differential pair | 5 V-tolerant, slew-rate controlled outputs - require external CAN transceiver (e.g., TJA1043) and 120 Ω termination for ISO 11898-1/CAN-FD physical layer compliance. |
| ADC0_SE0–ADC0_SE31 | Analog input channels | Support multiplexed sampling across 32 pins; internal reference (VREFH) must be stable ±1% for <1 LSB INL error in 12-bit conversion. |
Key Features
| Feature | Design Value |
|---|---|
| HSRUN/RUN Power Modes | 112 MHz peak performance in HSRUN for real-time control loops; automatic fallback to 80 MHz RUN mode required for CSEc or EEPROM operations - enforces deterministic timing isolation between compute and security functions. |
| System MPU Protection | NXP's crossbar-level MPU assigns per-master (Core, DMA, Ethernet) access rights to memory regions - prevents unauthorized peripheral or memory access without relying on Arm Core MPU, meeting ASIL-B memory protection requirements. |
| FlexIO Module | Configurable logic block supporting UART, SPI, I2C, LIN, PWM, or custom protocols on 8 pins - eliminates need for external protocol translators in gateway or sensor interface designs. |
| LPIT & LPTMR Timers | 32-bit Low Power Interrupt Timer (4 channels) and 16-bit Low Power Timer with wake-up capability - enable precise sleep-state timing and periodic sensor polling while consuming <10 µA in VLPS mode. |
| Ethernet + SAI | 10/100 Mbps IEEE 1588-capable MAC with two Synchronous Audio Interface modules - supports time-sensitive networking (TSN) and digital audio streaming in infotainment head units. |
Applications
| Engine Control Unit (ECU) | Advanced Driver Assistance Systems (ADAS) Sensor Hub |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K144HAT0MLHT | Same die, identical electrical specs, but supplied in trays (T) instead of tape-and-reel (R); no functional difference. | Preferred for low-volume prototyping or manual assembly where reel handling is impractical. | Select MLHT when small-batch evaluation or hand-soldering is required; MLHR remains optimal for automated SMT production. |
| S32K146HAT0MLHR | Pin-compatible upgrade with 1 MB flash (vs. 2 MB), 512 KB SRAM, and identical 144-pin LQFP package; same CSEc, FlexCAN, and ADC capabilities. | Suitable for cost-sensitive ECUs where full 2 MB flash is unused - reduces BOM cost without layout change. | Choose K146 only if firmware size is confirmed ≤512 KB and no future expansion beyond 512 KB SRAM is planned. |
Compared with FX32K144HAT0MLHR, the MLHT variant offers identical functionality in tray packaging for prototyping, while the S32K146HAT0MLHR provides a lower-memory, pin-compatible option for cost-optimized deployments - neither is a drop-in replacement for higher memory or security-critical applications requiring the full 2 MB flash and certified CSEc implementation.

FAQ
What is the maximum operating frequency of FX32K144HAT0MLHR, and under what conditions is it guaranteed?
FX32K144HAT0MLHR operates at up to 112 MHz in HSRUN mode, guaranteed across -40 °C to +125 °C ambient temperature per datasheet Table 5. This frequency requires VDD ≥2.7 V and is limited to RUN-mode peripherals; CSEc or EEPROM operations must occur at 80 MHz in RUN mode to avoid error flag assertion.
Does FX32K144HAT0MLHR support CAN-FD, and how many channels are available?
Yes, FX32K144HAT0MLHR integrates three FlexCAN modules, each supporting CAN-FD per ISO 11898-1. All three channels are fully functional in the 144-pin LQFP package, with dedicated TX/RX pins mapped to separate port groups to enable independent routing and termination.
What memory protection mechanisms does FX32K144HAT0MLHR implement for functional safety compliance?
FX32K144HAT0MLHR uses NXP's system MPU at the crossbar switch level - not the Arm Core MPU - to assign per-master (CPU, DMA, Ethernet) access rights to memory regions. This architecture enforces ASIL-B memory protection by preventing unauthorized access to safety-critical code and data sections.
Can FX32K144HAT0MLHR execute CSEc cryptographic operations in HSRUN mode?
No. Per datasheet Section 1.1 and Figure 3 footnotes, CSEc (Security) or EEPROM write/erase operations will trigger error flags if attempted in HSRUN mode (112 MHz). FX32K144HAT0MLHR must switch to RUN mode (80 MHz) to execute these functions - a mandatory design constraint for secure boot and key provisioning sequences.
What is the ADC resolution and channel count supported by FX32K144HAT0MLHR?
FX32K144HAT0MLHR includes two independent 12-bit SAR ADC modules, supporting up to 32 analog input channels total (16 per module). Each ADC achieves 1 Msps sampling rate with hardware trigger synchronization via TRGMUX, enabling precise multi-sensor acquisition in engine control applications.
