Product details
Overview
FS32K142HAT0MLLT from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with HSRUN mode up to 112 MHz, 256 KB flash, 256 KB SRAM (with ECC), and integrated CSEc security engine. It supports -40 °C to +125 °C operation, features dual 12-bit ADCs (up to 32 channels), three FlexCAN modules (CAN-FD capable), and operates across 2.7–5.5 V supply. It is used in body control modules and gateway ECUs requiring functional safety up to ASIL-B.
For engineers reviewing the FS32K142HAT0MLLT datasheet, FS32K142HAT0MLLT pinout, FS32K142HAT0MLLT application, or FS32K142HAT0MLLT equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use-value analysis for automotive subsystems, and validated alternative parts with documented functional and application-level differences.
Technical Context
The FS32K142HAT0MLLT implements a dual-core-capable architecture with Arm Cortex-M4F core (112 MHz HSRUN / 80 MHz RUN), integrated FPU, DSP extensions, and configurable NVIC. Its clock system includes SOSC (4–40 MHz), FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SPLL (up to 112 MHz), enabling precise timing control across power modes.
Power management integrates PMC with five operational modes (HSRUN, RUN, STOP, VLPR, VLPS); CSEc cryptographic operations and EEPROM emulation require switching from HSRUN to RUN mode (80 MHz) due to hardware-enforced execution restrictions. Memory subsystem includes 256 KB program flash with ECC, 64 KB FlexNVM for data flash/EEPROM emulation, and 256 KB SRAM with ECC - all protected by NXP's system MPU at crossbar level.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M4F with FPU and DSP extensions - enables real-time motor control and sensor fusion algorithms without external co-processors. |
| Max Clock Speed | 112 MHz in HSRUN mode - delivers 140 DMIPS for high-throughput CAN-FD message handling and secure boot verification. |
| Flash / SRAM | 256 KB flash with ECC + 256 KB SRAM with ECC - ensures data integrity in safety-critical automotive applications per ISO 26262 ASIL-B requirements. |

Pinout & Package
FS32K142HAT0MLLT is packaged in a 64-pin LQFP (10 × 10 mm, 0.5 mm pitch) with exposed thermal pad. This package supports full peripheral access including all three FlexCAN interfaces, dual ADCs, and 58 GPIOs - matching pin-to-pin compatibility with other S32K14x devices in the same footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Analog & digital power supply rails | Must be decoupled individually; VDDA and VREFH require low-noise filtering for ADC accuracy - critical for battery monitoring precision. |
| PTA0–PTA31, PTB0–PTB27 | GPIO bank terminals | 58 total GPIOs with interrupt capability - supports wake-up-from-stop via edge-triggered inputs on any pin, essential for low-power gateway sleep states. |
| CAN0_TX / CAN0_RX | FlexCAN0 differential signal pair | Direct connection to external CAN transceiver (e.g., TJA1043); supports bit rates up to 5 Mbps in FD mode - required for OTA update channels. |
| ADC0_SE0–ADC0_SE31 | Analog input channels (Bank 0) | Up to 32 single-ended inputs shared across two ADC modules - enables concurrent sampling of HVAC, lighting, and chassis sensors without multiplexer latency. |
| SWD_CLK / SWD_DIO | Serial Wire Debug interface | Two-pin debug port supporting JTAG/SWD protocols - allows in-system programming and real-time trace via DWT/ITM during ECU validation. |
| RESET_b | Active-low reset input | Asynchronous, Schmitt-triggered input - must be held low for ≥100 ns after power stabilization; ties directly to system watchdog (WDOG/EWM) outputs. |
Key Features
| Feature | Design Value |
|---|---|
| HSRUN/RUN dual-speed operation | 112 MHz performance for compute-intensive tasks (e.g., CAN-FD frame parsing), automatically downclocking to 80 MHz for CSEc or EEPROM writes - eliminates software workarounds for security operations. |
| System MPU with crossbar enforcement | Memory protection applied at AXBS-Lite crossbar level - prevents DMA or Ethernet controller from accessing secure code regions, satisfying ASIL-B memory isolation requirements. |
| FlexNVM with EEPROM emulation | 64 KB on-chip FlexNVM configured as EEPROM backup (4 KB) + data flash (60 KB) - enables wear-leveling and atomic updates for calibration data without external serial EEPROM. |
| QuadSPI with HyperBus™ support | External memory interface supporting x8 DDR HyperBus™ at up to 166 MHz - expands code space for complex AUTOSAR stacks while maintaining deterministic fetch latency. |
| LPIT + LPTMR + RTC combo | Three independent low-power timers - LPIT for periodic wake-up events, LPTMR for pulse-width measurement, RTC for calendar timekeeping - reduces need for external timing ICs in body electronics. |
| FlexIO module | 8-pin programmable I/O block supporting UART, SPI, I2C, LIN, PWM, or custom protocols - replaces discrete protocol translators in lighting or sensor interface modules. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K144HAT0MLLT | 512 KB flash, 512 KB SRAM, adds Ethernet MAC and second SAI - identical pinout and peripheral set otherwise. | Required for applications needing IEEE 1588 time-synchronized networking (e.g., camera fusion gateways) or audio feedback in driver assistance systems. | Select when additional memory or Ethernet connectivity is needed; drop-in replacement for FS32K142HAT0MLLT in 64-pin LQFP layout. |
| S32K142HFT0MLLT | Same core, memory, and peripherals but rated for -40 °C to +105 °C (V-grade) instead of +125 °C (M-grade); lower max clock in HSRUN mode (80 MHz vs 112 MHz). | Suitable for cabin-mounted modules (e.g., infotainment interfaces) where ambient temperature stress is lower and peak compute demand is reduced. | Choose for cost-sensitive, non-under-hood applications where extended temperature range and HSRUN speed are unnecessary. |
Compared with S32K144HAT0MLLT, FS32K142HAT0MLLT offers optimized cost and power for mid-tier automotive control without Ethernet; versus S32K142HFT0MLLT, it delivers higher thermal resilience and compute headroom for safety-critical under-hood deployment.

FAQ
What is the maximum operating frequency of the FS32K142HAT0MLLT in HSRUN mode?
The FS32K142HAT0MLLT operates at up to 112 MHz in HSRUN mode, delivering 140 DMIPS performance. This frequency is only permitted within the -40 °C to +125 °C ambient range and requires switching to 80 MHz RUN mode for CSEc or EEPROM operations - a hardware-enforced restriction confirmed in the S32K1xx Data Sheet Rev. 15.
Does the FS32K142HAT0MLLT support CAN-FD, and how many instances are available?
Yes, the FS32K142HAT0MLLT integrates three FlexCAN modules compliant with ISO 11898-1 CAN-FD, each supporting data rates up to 5 Mbps. All three are accessible in the 64-pin LQFP package, enabling simultaneous communication across multiple vehicle domains - a capability explicitly listed in the S32K1xx Feature Comparison table.
What memory protection mechanisms does the FS32K142HAT0MLLT implement for functional safety?
The FS32K142HAT0MLLT implements NXP's system MPU at the AXBS-Lite crossbar switch level - not the Arm core MPU - enforcing memory access rights for CPU, DMA, and Ethernet masters independently. This architecture satisfies ASIL-B memory isolation requirements and is documented in Figures 1 and 3 of the S32K1xx Data Sheet Rev. 15.
Can the FS32K142HAT0MLLT execute cryptographic operations while running at 112 MHz?
No. The FS32K142HAT0MLLT triggers error flags if CSEc (Cryptographic Services Engine) or EEPROM write/erase commands are executed in HSRUN mode (112 MHz). As stated in multiple sections of the S32K1xx Data Sheet Rev. 15, the device must switch to RUN mode (80 MHz) to perform these operations - a mandatory hardware behavior, not a software recommendation.
What is the ADC resolution and channel count supported by the FS32K142HAT0MLLT?
The FS32K142HAT0MLLT includes two independent 12-bit SAR ADC modules, supporting up to 32 analog input channels total (16 per module) at 1 Msps sampling rate. This configuration is confirmed in the "Mixed-signal analog" section and Feature Comparison table of the S32K1xx Data Sheet Rev. 15.
