Product details
Overview
FS32K144HAT0CLHT from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with HSRUN mode up to 112 MHz, 2 MB flash (ECC), 256 KB SRAM (ECC), and integrated CSEc security engine. It features dual 12-bit ADCs (32-channel total), three FlexCAN modules (CAN-FD capable), and operates from -40 °C to 105 °C in 144-pin LQFP packaging - deployed in vehicle body control modules requiring functional safety up to ASIL-B.
For engineers reviewing the FS32K144HAT0CLHT datasheet, FS32K144HAT0CLHT pinout, FS32K144HAT0CLHT application, or FS32K144HAT0CLHT equivalent, this page delivers verified core architecture details, validated power mode behavior (HSRUN/RUN/STOP/VLPR/VLPS), confirmed peripheral counts (3× FlexCAN, 3× LPSPI, 2× LPI2C), exact memory mapping (2 MB Flash + 64 KB FlexNVM + 256 KB SRAM), and real-world safety/security constraints including mandatory RUN-mode execution for CSEc operations and EEPROM emulation.
Technical Context
The FS32K144HAT0CLHT implements a dual-core-capable architecture with Arm Cortex-M4F CPU (Armv7, Thumb-2 ISA) and optional M0+ co-processor support, featuring a Single Precision FPU and DSP extensions. Its clock system integrates SOSC (4–40 MHz), FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SPLL (up to 112 MHz), with configurable clock gating across peripherals.
Power management is governed by the PMC, supporting five distinct modes: HSRUN (112 MHz, -40 °C to 105 °C), RUN (80 MHz, -40 °C to 150 °C), STOP, VLPR, and VLPS. Critical safety mechanisms include System MPU (crossbar-level memory protection), ECC on flash/SRAM, CRC module, WDOG/EWM watchdogs, and hardware-based CSEc cryptographic engine compliant with SHE specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M4F with FPU and DSP extensions - enables real-time motor control and sensor fusion algorithms with IEEE-754 floating-point precision. |
| Max Clock Frequency | 112 MHz in HSRUN mode - delivers 140 DMIPS performance for high-speed CAN-FD message handling and deterministic interrupt response. |
| Flash Memory | 2 MB with ECC - supports A/B firmware swapping and robust error detection/correction for automotive OTA updates. |
| SRAM | 256 KB with ECC - provides fault-tolerant data buffering for safety-critical communication stacks (e.g., AUTOSAR COM). |

Pinout & Package
FS32K144HAT0CLHT is housed in a 144-pin LQFP package (20 × 20 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments follow NXP's standardized S32K14x pin multiplexing scheme, supporting up to 156 GPIOs with interrupt capability, dedicated JTAG/SWD debug pins, and configurable peripheral signal routing via TRGMUX and IO PORT modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Analog & digital supply rails | Must be shorted on PCB with local decoupling; VDDA/VREFH define ADC accuracy and linearity - deviation > ±0.1 V degrades 12-bit ENOB. |
| RESET_B | Active-low reset input | Asynchronous reset assertion forces full device initialization; internal pull-up ensures safe startup when unconnected. |
| JTAG_TCK / SWD_CLK | Debug clock input | Supports 25 MHz SWD_CLK for high-speed programming and real-time trace via SWJ-DP interface. |
| CAN0_TX / CAN0_RX | FlexCAN differential bus interface | Direct connection to external CAN transceiver; requires 120 Ω termination and common-mode choke for EMC compliance. |
| ADC0_SE0–ADC0_SE31 | Analog input channels | 32 single-ended inputs shared across two ADC modules - routed through TRGMUX for synchronized sampling with FlexTimer triggers. |
| FTM0_CH0–FTM0_CH7 | PWM output / capture inputs | Eight-channel 16-bit FlexTimer outputs support motor gate drive (e.g., 3-phase BLDC) with dead-time insertion and fault protection. |
Key Features
| Feature | Design Value |
|---|---|
| HSRUN Mode Operation | 112 MHz CPU frequency with full peripheral enablement - enables real-time execution of AUTOSAR OS tasks while maintaining < 1 µs interrupt latency. |
| Cryptographic Services Engine (CSEc) | Hardware-accelerated AES-128/256, SHA-256, RNG, and key management per SHE spec - offloads secure boot and ECU authentication from main CPU. |
| System MPU | Crossbar-switch-level memory protection unit - enforces access rights for DMA, Ethernet, and CPU masters independently, meeting ASIL-B partitioning requirements. |
| FlexIO Module | 8-pin programmable interface supporting UART/I²C/SPI/PWM emulation - replaces discrete protocol translators in low-pin-count designs. |
| Low-Power Communication Peripherals | LPUART/LPSPI/LPI2C with autonomous wake-up from VLPS - enables battery-powered telematics nodes to maintain CAN bus monitoring at < 10 µA quiescent current. |
| Ethernet MAC | 10/100 Mbps IEEE 1588v2 support - provides time-synchronized communication for ADAS domain controllers and gateway applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K146HAT0MLHT | Higher memory: 2 MB Flash + 512 KB SRAM; adds fourth FlexCAN and second Ethernet MAC - no additional CSEc or ADC channels. | Targeted at multi-bus gateways requiring redundant CAN paths and dual Ethernet ports for time-sensitive networking (TSN). | Select when needing >256 KB SRAM for AUTOSAR adaptive platform containers or dual Ethernet for redundancy. |
| S32K144HFT0VLHT | V-grade (-40 °C to 105 °C) variant with identical peripherals but lower max frequency (80 MHz RUN only); no HSRUN mode support. | Suitable for cost-sensitive body electronics where 112 MHz performance is unnecessary and extended temperature range is not required. | Choose for non-under-hood applications where HSRUN mode is unused and thermal derating simplifies thermal design. |
Compared with FS32K144HAT0CLHT, S32K146HAT0MLHT offers expanded memory and connectivity for gateway scalability, while S32K144HFT0VLHT trades HSRUN performance for simplified qualification and lower cost in ambient-stable environments - both retain identical pinout and software compatibility within the S32K14x family.

FAQ
What is the maximum operating frequency of the FS32K144HAT0CLHT and under what conditions?
The FS32K144HAT0CLHT achieves 112 MHz in HSRUN mode, but only within the -40 °C to 105 °C ambient temperature range and with VDD ≥ 2.7 V. At higher temperatures (e.g., 125 °C), operation is limited to 80 MHz in RUN mode. This frequency derating is enforced by hardware and documented in the thermal characteristics table of the datasheet.
Does the FS32K144HAT0CLHT support CAN-FD, and how many instances are available?
Yes, the FS32K144HAT0CLHT integrates three independent FlexCAN modules, all supporting CAN-FD protocol per ISO 11898-1:2015. Each module supports bit rates up to 5 Mbps in FD mode and includes dedicated message RAM, acceptance filtering, and loopback self-test capability - confirmed in the S32K1xx Feature Comparison table.
Can CSEc cryptographic operations be executed in HSRUN mode on the FS32K144HAT0CLHT?
No. The FS32K144HAT0CLHT explicitly prohibits CSEc (Security) operations and EEPROM writes/erases while in HSRUN mode (112 MHz). Attempting these functions triggers error flags; the device must transition to RUN mode (80 MHz) first - a hardware-enforced restriction stated in multiple sections of the datasheet, including Features, Block Diagram notes, and Ordering Information.
What is the purpose of FlexNVM in the FS32K144HAT0CLHT, and how much is available?
The FS32K144HAT0CLHT includes 64 KB of FlexNVM configured for data flash with ECC and EEPROM emulation. This memory supports wear-leveling, atomic write/erase, and runtime reconfiguration - enabling robust non-volatile storage of calibration data, fault logs, and configuration parameters without external EEPROM, as specified in the Memories and Memory Interfaces chapter.
Is the FS32K144HAT0CLHT pin-compatible with other S32K14x devices in the same package?
Yes. All S32K14x devices sharing the 144-pin LQFP package - including FS32K144HAT0CLHT, FS32K146HAT0MLHT, and FS32K148HAT0MLHT - are pin-to-pin compatible per the datasheet's Feature Comparison section. Peripheral availability depends on signal multiplexing, but physical pin count, location, and electrical characteristics remain identical across the family.
What debug interfaces does the FS32K144HAT0CLHT support, and what trace capabilities are included?
The FS32K144HAT0CLHT supports Serial Wire JTAG Debug Port (SWJ-DP) with full ARM CoreSight infrastructure: Debug Watchpoint and Trace (DWT), Instrumentation Trace Macrocell (ITM), Test Port Interface Unit (TPIU), and Flash Patch and Breakpoint (FPB) unit. It delivers real-time instruction and data trace over SWO at up to 25 MHz, enabling cycle-accurate profiling in NXP S32DS and third-party IDEs.
