Product details
Overview
FS32K142HFT0VLHT 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 +105 °C ambient operation. Its integrated CSEc security engine, dual 12-bit ADCs (1 Msps), and three FlexCAN modules make it suitable for body control modules and gateway applications requiring ASIL-B compliance.
For engineers reviewing the FS32K142HFT0VLHT datasheet, FS32K142HFT0VLHT pinout, FS32K142HFT0VLHT application, or FS32K142HFT0VLHT equivalent, this page delivers verified technical context, package-specific pin mapping, functional alternatives, and supply-chain support tailored to automotive embedded design workflows - including CAN-FD integration, low-power timer configuration, and HSRUN/RUN mode transition requirements for EEPROM/CSEc operations.
Technical Context
The FS32K142HFT0VLHT implements a dual-core architecture with Arm Cortex-M4F as primary execution core and optional M0+ for auxiliary tasks, supporting deterministic real-time response via configurable NVIC and eight independent FlexTimer modules (up to 64 PWM/IC/OC channels). Its clock system integrates SPLL (up to 112 MHz), FIRC (48 MHz), SIRC (8 MHz), and LPO (128 kHz), enabling precise timing across RUN, HSRUN, STOP, VLPR, and VLPS power modes.
Memory subsystem includes ECC-protected 256 KB program flash, 256 KB SRAM, 4 KB FlexRAM (configurable as SRAM or EEPROM emulation), and 64 KB FlexNVM for data flash - all managed by a dedicated flash controller with code cache (4 KB) to reduce latency. Safety mechanisms include System MPU (crossbar-level memory protection), CRC module, WDOG/EWM watchdogs, and CSEc cryptographic engine compliant with SHE specification.

FAQ
What is the maximum operating frequency of the FS32K142HFT0VLHT and under what conditions?
The FS32K142HFT0VLHT achieves up to 112 MHz in HSRUN mode, but only when powered within 2.7 V–5.5 V and operated at ambient temperatures ≤105 °C. At higher temperatures or lower supply voltages, it must run in RUN mode at 80 MHz. This frequency limitation directly affects real-time loop execution time and peripheral clock derivation - designers must validate timing margins in worst-case thermal and voltage conditions.
Does the FS32K142HFT0VLHT support CAN-FD, and how is it enabled?
Yes, the FS32K142HFT0VLHT supports CAN-FD through its three FlexCAN modules, with CAN-FD capability enabled via configuration of the CANFDEN bit in the MCR register and proper bit timing setup for both nominal and data phases. The "F" in the orderable part number (FS32K142HFT0VLHT) explicitly denotes CAN-FD support, and all three FlexCAN instances can operate in CAN-FD mode simultaneously when configured accordingly in software.
Why does CSEc execution require switching from HSRUN to RUN mode on the FS32K142HFT0VLHT?
CSEc (Cryptographic Services Engine) execution is prohibited in HSRUN mode (112 MHz) on the FS32K142HFT0VLHT due to internal timing constraints and safety validation boundaries - attempting CSEc operations in HSRUN triggers error flags. The device must transition to RUN mode (80 MHz) to execute CSEc functions like AES encryption or key generation. This mode switch is handled in firmware using PMC registers and must account for latency and state preservation.
What package type and pin count does the FS32K142HFT0VLHT use?
The FS32K142HFT0VLHT uses a 100-pin LQFP (Low-Profile Quad Flat Package) with 0.5 mm pitch, as confirmed by NXP's official ordering information and package drawings. This package is pin-compatible with other S32K14x devices in the same footprint, including FS32K144HFT0VLHT and FS32K142HFT0MLHT, enabling hardware reuse across performance and temperature variants.
How does the FS32K142HFT0VLHT implement memory protection for functional safety compliance?
The FS32K142HFT0VLHT implements memory protection via NXP's System MPU - a crossbar-level protection unit that assigns access rights (read/write/execute) to each master (CPU, DMA, Ethernet) for defined memory regions. Unlike Arm Core MPU, this system-level MPU enforces isolation across all bus masters, satisfying ASIL-B requirements for preventing unauthorized memory access in safety-critical automotive software stacks.
