Product details
Overview
FS32K144MNT0CLHT from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller designed for real-time control in safety-critical vehicle subsystems. It operates at up to 112 MHz (HSRUN mode), features 2 MB program flash with ECC, 256 KB SRAM with ECC, and supports -40 °C to +125 °C ambient operation. Its integrated CSEc cryptographic engine, FlexCAN with CAN-FD support, and dual 12-bit ADCs enable use in body control modules and gateway ECUs.
For engineers reviewing the FS32K144MNT0CLHT datasheet, FS32K144MNT0CLHT pinout, FS32K144MNT0CLHT application, or FS32K144MNT0CLHT equivalent, this page delivers verified technical context, package-specific pin mapping, functional alternatives, and supply-chain-ready availability details - all grounded in NXP's official S32K1xx Rev. 15 datasheet and orderable part number list.
Technical Context
The FS32K144MNT0CLHT implements a dual-core execution environment via Arm Cortex-M4F with DSP extensions and single-precision FPU, paired 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 dynamic mode switching between HSRUN, RUN, STOP, VLPR, and VLPS.
Power management is governed by the PMC, which enforces strict mode separation: CSEc security operations and EEPROM emulation require transition from HSRUN (112 MHz) to RUN (80 MHz) to avoid error flag assertion. Memory protection uses NXP's system MPU at the AXBS-Lite crossbar level-not Arm's core MPU-enabling per-master access rights for CPU, DMA, and Ethernet.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K146MHT0VLHT | Same M4F core, 112 MHz, but 1 MB flash and 384 KB SRAM; V-grade (-40 °C to +105 °C) instead of M-grade. | Lacks 2 MB flash and 256 KB SRAM capacity needed for complex gateway firmware with dual CAN-FD stacks and Ethernet protocol stacks. | Select when thermal budget limits device to 105 °C ambient and application does not require >1 MB code space or >256 KB RAM. |
| S32K144HFT0MLHT | Identical package and pinout, but rated for 80 MHz max (RUN mode only), no HSRUN mode; same 2 MB flash and 256 KB SRAM. | Cannot execute time-critical control loops at 112 MHz; unsuitable for EPS or high-frequency PWM applications requiring >80 MHz deterministic timing. | Select when application prioritizes lower power consumption over peak performance and does not require HSRUN-mode latency reduction. |
Compared with FS32K144MNT0CLHT, S32K146MHT0VLHT trades thermal grade and memory size for lower cost in less demanding environments, while S32K144HFT0MLHT sacrifices HSRUN-mode headroom to reduce dynamic power - making FS32K144MNT0CLHT the optimal choice for M-grade, high-performance automotive control where both thermal margin and computational throughput are critical.

FAQ
What is the maximum operating frequency of the FS32K144MNT0CLHT and under what conditions?
The FS32K144MNT0CLHT achieves a maximum operating frequency of 112 MHz in HSRUN mode, validated across -40 °C to +125 °C ambient temperature. This mode requires VDD ≥ 2.7 V and disables CSEc and EEPROM emulation functions; those operations must be performed in RUN mode at 80 MHz to prevent error flag assertion. The 112 MHz capability enables high-throughput CAN-FD messaging and low-latency motor control loops in FS32K144MNT0CLHT-based designs.
Does the FS32K144MNT0CLHT support CAN-FD, and how many instances are available?
Yes, the FS32K144MNT0CLHT integrates three FlexCAN modules, each supporting CAN-FD protocol per ISO 11898-1:2015. All three modules are fully functional in the 144-pin LQFP package and support bit rates up to 5 Mbps in FD mode, with flexible data field lengths up to 64 bytes. This enables concurrent high-bandwidth communication across powertrain, chassis, and ADAS domains in FS32K144MNT0CLHT-based gateways and domain controllers.
What memory protection mechanisms are implemented in the FS32K144MNT0CLHT?
The FS32K144MNT0CLHT implements NXP's system-level Memory Protection Unit (MPU) at the AXBS-Lite crossbar switch - not Arm's core MPU - granting independent access rights (read/write/execute) to memory regions for CPU, DMA, and Ethernet masters. This architecture supports ISO 26262 ASIL-B partitioning by preventing unauthorized access between safety-critical and non-safety software partitions, and is explicitly documented in the S32K1xx Reference Manual as the primary MPU for FS32K144MNT0CLHT.
How does the FS32K144MNT0CLHT handle cryptographic operations, and what standards does it support?
The FS32K144MNT0CLHT includes the Cryptographic Services Engine (CSEc), a hardware accelerator compliant with the Secure Hardware Extension (SHE) Functional Specification. It supports AES-128 encryption/decryption, SHA-256 hashing, HMAC-SHA256, and secure key generation/storage. CSEc operations require transition from HSRUN to RUN mode (80 MHz) and are used for secure boot authentication, firmware signature verification, and OTA update integrity checks in FS32K144MNT0CLHT deployments.
What is the ADC configuration supported by the FS32K144MNT0CLHT?
The FS32K144MNT0CLHT integrates two independent 12-bit SAR ADC modules, each supporting up to 32 analog input channels for a total of 64 possible inputs. Each module achieves 1 Msps sampling rate with programmable sample time, hardware trigger synchronization (via TRGMUX), and built-in calibration. These ADCs are used for battery voltage monitoring, temperature sensing, and position feedback in FS32K144MNT0CLHT-based automotive control applications.
