Product details
Overview
FS32K142HRT0MLHR from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller designed for real-time control in safety-critical ECUs. It operates at up to 112 MHz (HSRUN mode), features 256 KB flash with ECC, 256 KB SRAM with ECC, and supports -40 °C to +125 °C ambient operation. Its integrated CSEc security engine, FlexCAN with CAN-FD support, and dual 12-bit ADCs make it suitable for body control modules and gateway applications.
For engineers reviewing the FS32K142HRT0MLHR datasheet, FS32K142HRT0MLHR pinout, FS32K142HRT0MLHR application, or FS32K142HRT0MLHR equivalent, key selection considerations include HSRUN/RUN mode switching constraints for EEPROM/CSEc operations, 100-pin LQFP package compatibility, ASIL-B capable peripherals, and verified CAN-FD timing compliance per ISO 11898-1.
Technical Context
The FS32K142HRT0MLHR implements a dual-core execution environment via Arm Cortex-M4F core with FPU and DSP extensions, coupled with configurable NVIC and DWT/ITM debug infrastructure. Its clock system integrates SPLL (up to 112 MHz), FIRC (48 MHz), SIRC (8 MHz), and LPO (128 kHz), enabling precise low-power timing control across HSRUN, RUN, STOP, VLPR, and VLPS modes.
Memory architecture includes ECC-protected 256 KB program flash, 256 KB SRAM, 4 KB FlexRAM (configurable as SRAM or EEPROM emulation), and QuadSPI with HyperBus™ support. Safety mechanisms include System MPU (crossbar-level memory protection), CRC module, WDOG/EWM watchdogs, and CSEc cryptographic engine compliant with SHE specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M4F with single-precision FPU and DSP extensions - enables deterministic floating-point math and signal processing in motor control loops. |
| Max Clock Frequency | 112 MHz in HSRUN mode; 80 MHz in RUN mode - HSRUN enables peak performance but disables CSEc/EEPROM writes; RUN required for secure operations. |
| Flash Memory | 256 KB with ECC - provides fault-tolerant code storage meeting ASIL-B requirements for automotive functional safety. |
| SRAM | 256 KB with ECC - supports real-time data buffering and safety-critical variable storage with error detection/correction. |
| ADC | Dual 12-bit SAR ADCs, up to 32 channels total, 1 Msps - enables simultaneous sampling of multiple sensor inputs (e.g., temperature, pressure, position). |
| FlexCAN | 2x CAN-FD modules (ISO 11898-1) - supports high-bandwidth in-vehicle networking with data rates up to 5 Mbps and extended payload length. |
| Temperature Range | -40 °C to +125 °C ambient (M-grade) - qualified for under-hood automotive environments including engine control units. |
| Supply Voltage | 2.7 V to 5.5 V - compatible with standard 3.3 V and 5 V automotive power domains without level-shifting. |
Pinout & Package
FS32K142HRT0MLHR is housed in a 100-pin LQFP package (14 × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments are defined in the S32K1xx Reference Manual IO Signal Description sheet; this package variant supports full peripheral availability including all 2x FlexCAN, 2x LPUART, 2x LPSPI, 2x LPI2C, dual ADCs, and 80 GPIOs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Analog & digital supply rails | Must be decoupled individually; VDD/VDDA differential ≤ ±0.1 V ensures ADC accuracy and I/O integrity. |
| RESET_B | Active-low reset input | Asynchronous reset assertion halts CPU, clears registers, and forces boot from reset vector - critical for fail-safe recovery. |
| SWD_CLK / SWD_IO | Serial Wire Debug interface | Enables non-intrusive debugging, flash programming, and real-time trace via SWJ-DP - no JTAG pins required. |
| CAN0_TX / CAN0_RX | Primary CAN-FD transceiver interface | Direct connection to external CAN transceiver (e.g., TJA1043); supports bit rates up to 5 Mbps with FD frame payloads. |
| ADC0_SE0–ADC0_SE15 | Analog input channels (Bank 0) | 16 dedicated pins for single-ended ADC0 inputs - supports multiplexed sensor monitoring with hardware trigger synchronization. |
| FLEXIO0_DATA0–FLEXIO0_DATA7 | Programmable I/O block signals | Configurable as UART/I²C/SPI/PWM - enables protocol bridging or custom peripheral emulation without additional ICs. |
Key Features
| Feature | Design Value |
|---|---|
| HSRUN/RUN power mode separation | 112 MHz performance available only when CSEc/EEPROM access is disabled - forces explicit mode transition for secure operations, preventing runtime conflicts. |
| System MPU (Crossbar-based) | Enforces memory access rights per master (CPU, DMA, Ethernet) - prevents unauthorized peripheral or memory region access, satisfying ASIL-B partitioning requirements. |
| Cryptographic Services Engine (CSEc) | Hardware-accelerated AES-128/256, SHA-256, RNG, and key management per SHE spec - enables secure boot, firmware authentication, and OTA update integrity. |
| Dual independent 12-bit ADCs | Each supports up to 16 channels, 1 Msps sampling, and hardware-triggered conversions - allows synchronized acquisition across two sensor domains (e.g., motor phase currents + temperature). |
| FlexCAN with CAN-FD | Two fully compliant CAN-FD controllers with Tx/Rx FIFOs, message RAM filtering, and bit-rate switching - supports high-throughput diagnostics and domain controller communication. |
| Low-power timer subsystem | LPIT (4-channel), LPTMR, RTC, and PDB - enables precise wake-up scheduling, PWM generation, and time-stamped event capture while consuming <10 µA in VLPS mode. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K144HRT0MLHR | 512 KB flash, 512 KB SRAM, 3x FlexCAN, 3x LPUART - larger memory and expanded peripheral count. | Required for gateway ECUs needing >256 KB application code space or triple CAN-FD domains. | Select when scaling beyond FS32K142HRT0MLHR's 256 KB flash limit or requiring third CAN-FD channel. |

FAQ
What is the maximum operating frequency of the FS32K142HRT0MLHR and under what conditions?
The FS32K142HRT0MLHR achieves 112 MHz in HSRUN mode, but this requires disabling CSEc cryptographic operations and EEPROM emulation. For secure functions like AES encryption or flash write/erase, the device must drop to RUN mode at 80 MHz. This dual-mode constraint is enforced in hardware to prevent concurrent high-speed execution and security-sensitive memory access - a design requirement validated in the S32K1xx Safety Manual.
Does the FS32K142HRT0MLHR support CAN-FD, and how many instances are available?
Yes, the FS32K142HRT0MLHR integrates two fully compliant FlexCAN modules supporting CAN-FD per ISO 11898-1, each with independent message RAM, Rx/Tx FIFOs, and bit-rate switching capability. Both controllers operate at up to 5 Mbps data phase and are accessible on dedicated pins in the 100-pin LQFP package - confirmed in the S32K1xx Pin Multiplexing document and validated in NXP's CAN-FD conformance test reports.
What memory protection mechanisms does the FS32K142HRT0MLHR implement for ASIL-B compliance?
The FS32K142HRT0MLHR employs a crossbar-switch-based System MPU that enforces memory access permissions per master (CPU, DMA, Ethernet), not just per core. This allows isolation of safety-critical tasks from non-safety partitions - a key requirement for ASIL-B decomposition. Combined with ECC on flash/SRAM and CRC hardware acceleration, it satisfies ISO 26262 Part 6 requirements for memory error detection and containment.
Can the FS32K142HRT0MLHR execute code from external memory via QuadSPI?
Yes, the FS32K142HRT0MLHR supports XIP (eXecute-In-Place) from external flash via its QuadSPI interface with HyperBus™ compatibility. This enables booting from external memory or offloading non-critical code to expand effective program space - documented in the S32K1xx Reference Manual Chapter "QuadSPI Controller" and validated using NXP's S32DS IDE with external memory configuration templates.
What is the purpose of the FlexRAM block in the FS32K142HRT0MLHR, and how is it configured?
The 4 KB FlexRAM in FS32K142HRT0MLHR is configurable either as general-purpose SRAM or as EEPROM emulation storage - managed by the FTFC flash controller. When used as EEPROM emulation, it provides wear-leveling and atomic write/erase operations without blocking CPU execution. Configuration is performed at runtime via FTFC command sequences, with settings retained across resets - detailed in the S32K1xx Reference Manual "FlexRAM" chapter.
