Product details
Overview
FS32K144HRT0MLHT 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), integrates 2 MB program flash with ECC, 256 KB SRAM with ECC, and supports -40 °C to +125 °C ambient operation. Key applications include body control modules and battery management systems requiring ASIL-B compliance.
For engineers reviewing the FS32K144HRT0MLHT datasheet, FS32K144HRT0MLHT pinout, FS32K144HRT0MLHT application, or FS32K144HRT0MLHT equivalent, this page delivers verified technical context, package-specific pin mapping, functional alternatives, and supply-chain support for automotive embedded design and production ramp-up.
Technical Context
The FS32K144HRT0MLHT implements a dual-core capable architecture with Arm Cortex-M4F core (112 MHz HSRUN / 80 MHz RUN) and integrated DSP, FPU, and NVIC. It features a system-level Memory Protection Unit (MPU) enforcing access rights across crossbar masters (core, DMA, Ethernet), not just CPU-initiated accesses.
Power management includes five distinct modes (HSRUN, RUN, STOP, VLPR, VLPS), with CSEc security operations and EEPROM emulation restricted to RUN mode (80 MHz) due to hardware arbitration constraints. Clocking combines SOSC (4–40 MHz), FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SPLL (up to 112 MHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M4F with DSP, FPU, and NVIC - enables deterministic real-time control with floating-point math and interrupt latency under 12 cycles. |
| Max Frequency | 112 MHz in HSRUN mode - delivers 140 DMIPS for high-speed motor control loops or sensor fusion algorithms. |
| Flash / SRAM | 2 MB program flash + 256 KB SRAM, both with ECC - ensures data integrity in automotive environments per ISO 26262 ASIL-B requirements. |
| Temperature Range | -40 °C to +125 °C (M-grade) - qualified for under-hood ECU deployment without derating. |
| Security | Cryptographic Services Engine (CSEc) compliant with SHE spec - provides AES-128, SHA-256, RNG, and secure boot key management. |
| I/O Count | Up to 156 GPIOs with NMI and configurable pull-ups/downs - supports complex peripheral routing and diagnostic monitoring in multi-sensor systems. |
| Peripherals | 3× FlexCAN (CAN-FD), 3× LPUART/LIN, 3× LPSPI, 2× LPI2C, 8× FTM, RTC, LPIT, PDB, ADC (2×12-bit, 32 ch), CMP+DAC - enables full vehicle network integration and mixed-signal control. |
Pinout & Package
FS32K144HRT0MLHT is housed in a 144-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch), pin-compatible with other S32K14x devices in the same footprint. This package supports full peripheral signal routing including CAN-FD, Ethernet, and high-speed ADC channels while maintaining thermal performance up to 125 °C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Power and analog reference supply | Must be decoupled locally; VDD/VDDA differential ≤ ±0.1 V ensures ADC accuracy and I/O robustness. |
| RESET_B | Active-low reset input | Asynchronous reset with internal pull-up; compatible with external watchdog monitors (EWM) and power-on reset circuits. |
| SWD_CLK / SWD_IO | Serial Wire Debug interface | Enables non-intrusive debug, trace, and flash programming via standard ARM SWD protocol without JTAG pins. |
| CAN0_TX / CAN0_RX | FlexCAN Channel 0 differential pair | Supports CAN-FD up to 5 Mbps; requires external transceiver and termination for bus compliance. |
| ADC0_SE0–ADC0_SE31 | Analog input channels (Bank 0) | 32 single-ended inputs shared across two 12-bit SAR ADCs; supports simultaneous sampling and hardware-triggered conversions. |
| FTM0_CH0–FTM0_CH7 | FlexTimer Module 0 outputs | Configurable as PWM, input capture, or output compare; supports dead-time insertion and complementary outputs for motor gate drive. |
Key Features
| Feature | Design Value |
|---|---|
| System MPU with Crossbar Enforcement | Prevents DMA or Ethernet master access to protected memory regions - critical for ASIL-B partitioning and fault containment. |
| FlexNVM with EEPROM Emulation | 64 KB FlexNVM enables wear-leveling and atomic write/erase for calibration data storage without external EEPROM. |
| QuadSPI with HyperBus™ Support | Enables direct XIP execution from external NOR flash - reduces boot time and extends code space beyond on-chip flash limits. |
| Low-Power Timer Suite | LPTMR, LPIT (4-channel), and RTC provide hierarchical wake-up sources - allows deep sleep with sub-millisecond latency response. |
| FlexIO Configurable Peripherals | 8-pin module emulates UART, SPI, I2C, I2S, LIN, or PWM - eliminates need for external protocol translators in cost-sensitive designs. |

FAQ
What is the maximum operating frequency of the FS32K144HRT0MLHT and under which conditions?
The FS32K144HRT0MLHT achieves 112 MHz in HSRUN mode, validated across -40 °C to +125 °C ambient temperature. This frequency requires VDD ≥ 2.7 V and is disabled during CSEc security operations or EEPROM emulation, which must execute in RUN mode at 80 MHz per hardware constraint. The device automatically transitions between modes via PMC registers.
Does the FS32K144HRT0MLHT support CAN-FD, and how many channels are available?
Yes, the FS32K144HRT0MLHT integrates three independent FlexCAN modules, each supporting CAN-FD protocol up to 5 Mbps. All three channels are fully accessible in the 144-pin LQFP package, with dedicated TX/RX pins routed to separate package balls to prevent crosstalk and ensure signal integrity in automotive harness environments.
What memory protection mechanisms does the FS32K144HRT0MLHT implement for ASIL-B compliance?
The FS32K144HRT0MLHT uses a system-level Memory Protection Unit (MPU) enforced at the AXBS-Lite crossbar switch, assigning granular access rights (read/write/execute) to each memory region for every master (CPU, DMA, Ethernet). This differs from Arm core MPU by protecting all bus initiators - satisfying ASIL-B partitioning requirements per ISO 26262 Part 6.
Can the FS32K144HRT0MLHT execute cryptographic operations while running at 112 MHz?
No. CSEc (Cryptographic Services Engine) operations - including AES encryption, SHA hashing, and secure boot key validation - are explicitly prohibited in HSRUN mode (112 MHz) per hardware design. The FS32K144HRT0MLHT must transition to RUN mode (80 MHz) before initiating any CSEc command; attempting otherwise triggers error flags and halts execution.
What is the ADC configuration supported by the FS32K144HRT0MLHT, and what is its sampling rate?
The FS32K144HRT0MLHT includes two independent 12-bit SAR ADC modules, each supporting up to 32 analog input channels (64 total). Each ADC achieves 1 Msps conversion rate with hardware-triggered sequencing, simultaneous sampling capability, and built-in calibration. Input multiplexing is managed via TRGMUX to synchronize with FTM or LPIT events.
