Product details
Overview
FS32K142MAT0MLHT 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 80 MHz in RUN mode, supports -40 °C to +125 °C ambient temperature, integrates 256 KB flash with ECC, 32 KB SRAM, and features CSEc cryptographic engine and dual 12-bit ADCs. It is used in body control modules requiring ASIL-B compliance and secure firmware updates.
For engineers reviewing the FS32K142MAT0MLHT datasheet, FS32K142MAT0MLHT pinout, FS32K142MAT0MLHT application, or FS32K142MAT0MLHT equivalent, key selection considerations include its M-grade temperature rating, 48-pin LQFP package, FlexCAN with optional CAN-FD support, HSRUN/RUN power mode constraints on CSEc/EEPROM operations, and compatibility with S32 Design Studio SDK for AUTOSAR and ISO 26262 development.
Technical Context
The FS32K142MAT0MLHT implements an Arm Cortex-M4F core with single-precision FPU and DSP extensions, executing at up to 80 MHz in RUN mode (HSRUN mode disabled per M-grade thermal limits). Its memory subsystem includes 256 KB program flash with ECC, 32 KB SRAM with ECC, 4 KB FlexRAM for EEPROM emulation, and a 4 KB code cache to reduce latency.
Peripherals are managed via AXBS-Lite crossbar switch and eDMA with DMAMUX, supporting concurrent low-power operation across LPUART, LPSPI, LPI2C, FlexCAN, and FlexIO. Safety mechanisms include System MPU (crossbar-level memory protection), CRC module, WDOG/EWM watchdogs, and CSEc engine compliant with SHE specification - all validated for ASIL-B systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M4F with FPU and DSP extensions - enables deterministic floating-point math and signal processing in motor control and sensor fusion. |
| Max Clock Frequency | 80 MHz in RUN mode - thermal limit for M-grade (-40 °C to +125 °C); HSRUN (112 MHz) not enabled on this variant. |
| Flash Memory | 256 KB with ECC - provides robust code storage with error detection/correction for automotive ECU reliability. |
| SRAM | 32 KB with ECC - ensures data integrity in real-time variables and stack operations under EMI or radiation stress. |
| ADC | Dual 12-bit SAR ADCs, up to 32 channels total - supports simultaneous sampling of multiple sensors (e.g., temperature, position, voltage) in body electronics. |
| FlexCAN | 1 module with optional CAN-FD support - delivers higher bandwidth and payload capacity for gateway or domain controller communication. |
| Security Engine | Cryptographic Services Engine (CSEc) - implements AES-128, SHA-256, RNG, and secure boot per SHE spec, but requires RUN mode (not HSRUN) for execution. |
| Package | 48-pin LQFP (7 mm × 7 mm, 0.5 mm pitch) - surface-mount compatible with standard automotive PCB assembly and thermal management. |
Pinout & Package
FS32K142MAT0MLHT is housed in a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch), optimized for automotive board space and thermal dissipation. Pin functions align with S32K14x family multiplexing; I/O count is up to 43 GPIOs depending on peripheral enablement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Power supply and analog reference | Must be decoupled locally; VDD/VDDA differential ≤ ±0.1 V ensures ADC accuracy and I/O noise immunity. |
| RESET_B | Active-low reset input | Asynchronous, level-sensitive reset - required for safe power-on initialization and fault recovery in automotive systems. |
| SWD_CLK / SWD_IO | Serial Wire Debug interface | Enables non-intrusive debug, trace, and flash programming without halting real-time operation. |
| CAN0_TX / CAN0_RX | FlexCAN transceiver interface | Direct connection to external CAN PHY; supports CAN 2.0B and optional CAN-FD with configurable bit timing. |
| ADC0_SE0–ADC0_SE15 | Analog input channels | Up to 16 single-ended inputs per ADC module - routed through TRGMUX for hardware-triggered conversions synchronized with timers or PWM. |
| LPUART0_RX / LPUART0_TX | Low-power UART interface | Supports LIN 2.2A protocol and deep-sleep wake-up - critical for battery-sensitive body control applications. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B capable architecture | System MPU enforces memory access rights per master (core/DMA), CRC validates data transfers, and dual watchdogs (WDOG + EWM) provide layered fault containment. |
| Flexible power management | Five power modes (RUN, STOP, VLPR, VLPS, HSRUN) - but HSRUN disabled on M-grade; RUN mode enables full peripheral set at 80 MHz with dynamic clock gating. |
| Secure firmware lifecycle | CSEc engine supports secure boot, AES-128 encryption, and key provisioning - all operable only in RUN mode (80 MHz), enforcing separation between performance and security states. |
| Robust analog integration | Dual 12-bit ADCs (1 Msps each) with hardware trigger mux and internal 8-bit DAC for comparator reference - eliminates need for external precision references in sensor conditioning. |
| Automotive communication suite | 1 FlexCAN (CAN-FD capable), 3 LPUART/LIN, 3 LPSPI, 2 LPI2C, FlexIO - enables mixed-protocol connectivity (e.g., LIN slave + CAN gateway + SPI sensor hub) on one die. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the maximum operating frequency of the FS32K142MAT0MLHT?
The FS32K142MAT0MLHT operates at up to 80 MHz in RUN mode. Its M-grade temperature rating (-40 °C to +125 °C) disables HSRUN mode (112 MHz), which is only supported on V- or W-grade variants. This 80 MHz limit ensures thermal stability and functional safety compliance in automotive under-hood applications where the FS32K142MAT0MLHT is deployed.
Does the FS32K142MAT0MLHT support CAN-FD?
Yes, the FS32K142MAT0MLHT includes one FlexCAN module that supports CAN-FD when configured in the appropriate mode. The CAN-FD capability must be enabled in software and requires an external CAN-FD transceiver. This feature is confirmed in the S32K1xx Data Sheet Rev. 15 and applies directly to the FS32K142MAT0MLHT as part of the S32K14x series.
Can CSEc security functions be executed in HSRUN mode on the FS32K142MAT0MLHT?
No - CSEc (Cryptographic Services Engine) operations, including secure boot and AES encryption, are explicitly prohibited in HSRUN mode per the S32K1xx Data Sheet. Since the FS32K142MAT0MLHT is M-grade and does not support HSRUN mode at all, all CSEc functions execute exclusively in RUN mode at 80 MHz, ensuring thermal and functional safety alignment.
What package type and pin count does the FS32K142MAT0MLHT use?
The FS32K142MAT0MLHT uses a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch), as specified in the S32K1xx Data Sheet Rev. 15 and confirmed by the ordering code "LH" in the part number. This package supports up to 43 GPIOs and is pin-compatible with other 48-pin S32K14x variants like FS32K144MAT0MLHT.
Is the FS32K142MAT0MLHT qualified for automotive applications?
Yes, the FS32K142MAT0MLHT is AEC-Q100 qualified for automotive use and designed to meet ASIL-B requirements per ISO 26262. It includes safety mechanisms such as System MPU, ECC on flash/SRAM, CRC module, dual watchdogs (WDOG and EWM), and lockstep-capable peripherals - all documented in the official S32K1xx Data Sheet and supported by NXP's safety documentation package.
