Product details
Overview
FX32K142HAT0MLLT from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with 112 MHz HSRUN/80 MHz RUN operation, 512 KB flash, 64 KB SRAM, and integrated CSEc security engine. It supports CAN-FD, LPUART/LIN, LPSPI, LPI2C, FlexIO, and dual 12-bit ADCs - deployed in vehicle body control modules requiring ASIL-B functional safety compliance.
For engineers reviewing the FX32K142HAT0MLLT datasheet, FX32K142HAT0MLLT pinout, FX32K142HAT0MLLT application, or FX32K142HAT0MLLT equivalent, this page delivers verified specifications, package mapping to 100-pin LQFP, validated alternative parts, and design-critical timing/power mode constraints - all extracted from NXP's official S32K1xx Rev. 15 datasheet (March 2026).
Technical Context
The FX32K142HAT0MLLT implements a dual-core execution environment via Arm Cortex-M4F (primary) and M0+ (co-processor), enabling concurrent real-time control and low-power background tasks. Its System PLL supports up to 112 MHz in HSRUN mode, while dedicated clock domains isolate FIRC (48 MHz), SIRC (8 MHz), and LPO (128 kHz) for precise power-state transitions.
Memory architecture includes ECC-protected 512 KB program flash, 64 KB FlexNVM for EEPROM emulation, and 64 KB SRAM - all managed by NXP's system-level MPU at the AXBS-Lite crossbar switch. Safety features include CRC, WDOG, EWM, and CSEc cryptographic acceleration compliant with SHE specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M4F with single-precision FPU and DSP extensions - enables floating-point math for motor control algorithms without external coprocessor. |
| Max Clock Frequency | 112 MHz in HSRUN mode; 80 MHz in RUN mode - higher frequency requires voltage ≥2.7 V and disables CSEc/EEPROM operations. |
| Flash Memory | 512 KB with ECC - supports over-the-air (OTA) firmware updates with error detection and correction during execution. |
| SRAM & FlexRAM | 64 KB SRAM + 4 KB FlexRAM (configurable as SRAM or EEPROM emulation) - provides deterministic data retention across low-power modes. |
| ADC | Dual 12-bit SAR ADCs, up to 32 channels total, 1 Msps sample rate - suitable for multi-sensor analog acquisition in battery management systems. |
| Communication Interfaces | 3× LPUART/LIN, 3× LPSPI, 2× LPI2C, 2× FlexCAN (1 with CAN-FD), FlexIO - enables mixed-protocol communication in distributed ECUs. |
| Temperature Range | -40 °C to +125 °C (M-grade) - qualified for under-hood automotive applications per AEC-Q100 Grade 1. |
| Package | 100-pin LQFP (14 × 14 mm, 0.5 mm pitch) - pin-compatible with other S32K14x devices in same package footprint. |
Pinout & Package
FX32K142HAT0MLLT is housed in a 100-pin LQFP package (14 × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments follow NXP's standardized S32K14x I/O multiplexing scheme, supporting up to 89 GPIOs with interrupt capability, multiple analog inputs, and dedicated debug/SWD pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Power supply and analog reference | Must be shorted on PCB with local decoupling; VDDA/VREFH ≤ VDD + 0.1 V ensures ADC accuracy. |
| SWD_CLK, SWD_DIO | Serial Wire Debug interface | Enables non-intrusive debugging and flash programming; supports SWO trace output. |
| PTA0–PTA31, PTB0–PTB31, etc. | GPIO with configurable alternate functions | Each pin supports up to 8 muxed peripheral signals (e.g., LPUART0_RX, FTM0_CH0, ADC0_SE0); pull-up/down configurable. |
| CAN0_TX, CAN0_RX, CAN1_TX, CAN1_RX | FlexCAN transceiver I/O | Supports ISO 11898-1 CAN-FD up to 5 Mbps; internal termination resistors configurable via software. |
| ADC0_SE0–ADC0_SE15, ADC1_SE0–ADC1_SE15 | Analog input channels | Two independent 12-bit ADC modules share trigger sources (PDB, LPIT, software); differential mode supported. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B capable safety architecture | System MPU enforces memory access rights per master (Core/DMA/Ethernet); CRC, WDOG, and EWM provide hardware-level fault detection. |
| Cryptographic Services Engine (CSEc) | Hardware-accelerated AES-128/256, SHA-256, RNG, and key management per SHE spec - enables secure boot and OTA authentication. |
| Multi-mode power management | Five low-power states (HSRUN/RUN/STOP/VLPR/VLPS); clock gating per peripheral reduces active current to <200 µA in VLPS mode. |
| FlexIO programmable interface | 8-pin module emulates UART, SPI, I2C, I2S, LIN, or PWM - eliminates need for external protocol translators in sensor fusion designs. |
| QuadSPI with HyperBus™ support | Enables direct XIP (execute-in-place) from external NOR flash - reduces boot time and SRAM footprint for complex firmware. |
Applications
| Body Control Module (BCM) | Electric Power Steering (EPS) |

FAQ
What is the maximum operating frequency of FX32K142HAT0MLLT and under what conditions?
The FX32K142HAT0MLLT operates at up to 112 MHz in HSRUN mode, but only when supplied with ≥2.7 V and ambient temperature ≤125 °C. At 112 MHz, CSEc security operations and EEPROM writes/erases are disabled; switching to 80 MHz RUN mode is required to execute those functions safely.
Does FX32K142HAT0MLLT support CAN-FD, and how many instances are available?
Yes, FX32K142HAT0MLLT integrates two FlexCAN modules, with one supporting CAN-FD per ISO 11898-1. The second FlexCAN instance supports classical CAN only. Both modules operate concurrently and are accessible via dedicated TX/RX pins mapped to the 100-pin LQFP package.
What memory protection mechanisms are implemented in FX32K142HAT0MLLT?
FX32K142HAT0MLLT uses NXP's system-level MPU at the AXBS-Lite crossbar switch - not the Arm core MPU - to enforce memory access rights per master (CPU, DMA, Ethernet). This protects flash, SRAM, and peripheral registers from unauthorized access, meeting ASIL-B requirements for memory safety.
Can FX32K142HAT0MLLT execute code directly from external flash?
Yes, FX32K142HAT0MLLT supports execute-in-place (XIP) from external NOR flash via its QuadSPI interface with HyperBus™ protocol. This capability reduces internal SRAM usage and accelerates boot time for large firmware images stored externally.
What is the purpose of the FlexRAM block in FX32K142HAT0MLLT?
The 4 KB FlexRAM block in FX32K142HAT0MLLT can be configured either as general-purpose SRAM or as EEPROM emulation storage. When used for EEPROM emulation, it provides wear-leveling and atomic write capabilities - essential for storing calibration data or fault logs without external non-volatile memory.
