Product details
Overview
FS32K142HRT0MLLT 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 FS32K142HRT0MLLT datasheet, FS32K142HRT0MLLT pinout, FS32K142HRT0MLLT application, or FS32K142HRT0MLLT equivalent, this page delivers verified technical context, package-specific pin mapping, functional alternatives, and supply-chain support tailored to automotive embedded design cycles.
Technical Context
The FS32K142HRT0MLLT implements an Arm Cortex-M4F core with single-precision FPU and DSP extensions, executing at 80 MHz in RUN mode (not 112 MHz HSRUN - disabled per M-grade thermal limits). Its memory subsystem includes 256 KB program flash with ECC, 32 KB SRAM with ECC, and 4 KB FlexRAM usable as SRAM or EEPROM emulation.
Peripheral integration includes three LPUART/LIN modules, two LPI2C interfaces, three LPSPI modules, one FlexCAN controller (CAN-FD capable), two 12-bit ADCs (up to 32 channels total), eight FlexTimer modules (16-bit, up to 64 channels), and a Cryptographic Services Engine (CSEc) compliant with SHE specification - all operating under PMC-managed power modes including RUN, STOP, VLPR, and VLPS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M4F with FPU and DSP extensions - enables deterministic real-time control with floating-point math for motor algorithms and sensor fusion. |
| Max Clock Frequency | 80 MHz in RUN mode - thermal limit for M-grade (-40 °C to +125 °C); HSRUN (112 MHz) is disabled on this variant. |
| Flash Memory | 256 KB with ECC - supports robust code storage and over-the-air update integrity verification in automotive applications. |
| SRAM | 32 KB with ECC - provides fault-tolerant data buffering for CAN message queues and safety-critical state variables. |
| ADC | Two 12-bit SAR ADCs, up to 32 total channels, 1 Msps - enables simultaneous sampling of battery voltage, temperature sensors, and actuator feedback in BCMs. |
| Cryptographic Engine | CSEc (Secure Hardware Extension) - implements AES-128/256, SHA-256, RNG, and key management per SHE spec for secure boot and ECU authentication. |
| FlexCAN | One module with CAN-FD support - allows high-bandwidth diagnostics and software flashing over CAN bus without protocol bottlenecks. |
| Operating Temperature | -40 °C to +125 °C ambient - qualified for under-hood automotive environments per AEC-Q100 Grade 1 (M-grade). |
Pinout & Package
FS32K142HRT0MLLT is packaged in a 48-pin LQFP (7 mm × 7 mm, 0.5 mm pitch), pin-compatible with other S32K14x devices in the same package option. This package supports full peripheral access including all three LPUARTs, two LPI2Cs, three LPSPIs, FlexCAN, ADC inputs, and GPIO with interrupt capability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Power and analog reference supply | Must be decoupled individually; VDDA and VREFH require low-noise filtering for 12-bit ADC accuracy. |
| RESET_b | Active-low reset input | Accepts external reset assertion; internal POR and LVD also generate reset - critical for fail-safe ECU recovery. |
| SWD_CLK, SWD_DIO | Serial Wire Debug interface | Enables non-intrusive debugging, flash programming, and runtime trace via standard ARM SWD protocol. |
| CAN0_TX, CAN0_RX | FlexCAN differential transceiver interface | Direct connection to external CAN transceiver (e.g., TJA1043); supports CAN-FD bit rates up to 5 Mbps. |
| ADC0_SE0–ADC0_SE15 | Analog input channels (Bank 0) | 16 single-ended inputs mapped to dedicated pins - used for voltage monitoring, thermistor reading, and potentiometer feedback. |
| LPUART0_RX, LPUART0_TX | Low-power UART interface | Supports LIN 2.2A frame handling and sleep/wake via break detection - essential for gateway and sensor node communication. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Capable Architecture | Integrated System MPU, ECC on flash/SRAM, CRC module, and dual watchdog (WDOG + EWM) enable ISO 26262-compliant system design. |
| Flexible Power Management | PMC supports five power modes (RUN, STOP, VLPR, VLPS, HSRUN); RUN mode at 80 MHz balances performance and thermal safety for M-grade operation. |
| Secure Boot & Firmware Updates | CSEc enforces authenticated boot and encrypted firmware images - prevents unauthorized code execution and ensures ECU identity in OTA workflows. |
| Dual High-Resolution ADCs | Two independent 12-bit, 1 Msps ADCs with configurable trigger sources (PDB, LPIT, FlexTimer) - enables synchronized sampling across multiple sensors. |
| Peripheral Crossbar Switch (AXBS-Lite) | Enables concurrent DMA transfers between eDMA, FlexCAN, LPUART, and ADC without CPU intervention - reduces latency in time-critical control loops. |
| FlexIO Module | Configurable logic block supporting UART, I²C, SPI, PWM, or custom protocols - replaces external glue logic in cost-sensitive body electronics designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K144HRT0MLLT | 512 KB flash, 64 KB SRAM, adds second FlexCAN and extra LPUART - no change in core frequency or temperature grade. | Required when larger code footprint or dual-CAN topology (e.g., separate comfort and powertrain networks) is needed. | Select FS32K144HRT0MLLT if future firmware expansion or redundant CAN routing is anticipated; pinout and PCB layout remain identical. |
| FS32K118MT0VLQT | Arm Cortex-M0+ core, 48 MHz max, 128 KB flash, V-grade (-40 °C to +105 °C), no CSEc or CAN-FD. | Suitable for cost-sensitive, non-safety-critical interior modules where cryptographic security and high-speed CAN are unnecessary. | Choose FS32K118MT0VLQT only for LIN-only nodes or simple switch controllers - not a functional replacement for FS32K142HRT0MLLT in ASIL-B systems. |
Compared with FS32K142HRT0MLLT, FS32K144HRT0MLLT offers scalable memory and connectivity while maintaining identical thermal rating and pin compatibility; FS32K118MT0VLQT trades security, performance, and temperature range for lower BOM cost in less demanding roles.

FAQ
What is the maximum operating frequency of the FS32K142HRT0MLLT?
The FS32K142HRT0MLLT operates at a maximum of 80 MHz in RUN mode. Although the S32K14x family supports 112 MHz in HSRUN mode, this capability is disabled on the M-grade (−40 °C to +125 °C) variant due to thermal constraints - confirmed by the datasheet's "Thermal operating characteristics" table and ordering code decoding ('H' = 80 MHz, 'M' = 125 °C).
Does the FS32K142HRT0MLLT support CAN-FD?
Yes, the FS32K142HRT0MLLT includes one FlexCAN module with CAN-FD support, enabling data rates up to 5 Mbps and payloads up to 64 bytes. This is explicitly stated in the "Features comparison" table (Figure 3) and confirmed by the ordering code 'F' in the Y-field - though FS32K142HRT0MLLT uses default feature set (Y = blank), CAN-FD is baseline for all S32K142 devices per datasheet section 3.1.
What package type is used for the FS32K142HRT0MLLT?
The FS32K142HRT0MLLT uses a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch), as indicated by the ordering code suffix 'LH'. This package is pin-compatible with other S32K14x variants in the same footprint and provides full access to all core peripherals including three LPUARTs, two LPI2Cs, and FlexCAN.
Is the FS32K142HRT0MLLT qualified for automotive use?
Yes, the FS32K142HRT0MLLT is AEC-Q100 qualified Grade 1 (M-grade), rated for −40 °C to +125 °C ambient operation. It includes integrated safety features - ECC on flash/SRAM, System MPU, dual watchdogs (WDOG/EWM), and CRC module - enabling ASIL-B system-level compliance per ISO 26262.
What debug interface does the FS32K142HRT0MLLT support?
The FS32K142HRT0MLLT supports Serial Wire Debug (SWD) via dedicated SWD_CLK and SWD_DIO pins, compatible with standard ARM CoreSight tools. It includes Debug Watchpoint and Trace (DWT), Instrumentation Trace Macrocell (ITM), and Flash Patch and Breakpoint (FPB) unit - enabling real-time tracing, non-intrusive breakpoints, and secure firmware debugging.
