Product details
Overview
FS32K144HRT0MMHR 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 2 MB program flash with ECC, 256 KB SRAM with ECC, and supports -40 °C to +125 °C ambient operation. Used in body control modules, gateway controllers, and battery management systems requiring ASIL-B compliance.
For engineers reviewing the FS32K144HRT0MMHR datasheet, FS32K144HRT0MMHR pinout, FS32K144HRT0MMHR application, or FS32K144HRT0MMHR equivalent, this page delivers verified technical context, package-specific pin mapping, functional alternatives, and supply-chain-ready availability details - all grounded in NXP's S32K1xx Rev. 15 datasheet and orderable part number list.
Technical Context
The FS32K144HRT0MMHR implements a dual-core-capable architecture with Arm Cortex-M4F core (Armv7, Thumb-2 ISA), integrated DSP, single-precision FPU, and configurable NVIC. Its clock system includes SOSC (4–40 MHz), FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SPLL supporting up to 112 MHz system frequency.
Power management uses PMC with five modes (HSRUN/RUN/STOP/VLPR/VLPS); HSRUN enables peak performance but disables CSEc and EEPROM operations - requiring mode switch to RUN (80 MHz) for security or data-flash writes. Memory protection relies on NXP's system MPU at crossbar level, not Arm Core MPU.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M4F with DSP extension and single-precision FPU - enables deterministic real-time signal processing and floating-point math without external coprocessor. |
| Max Clock Frequency | 112 MHz in HSRUN mode - delivers 140 DMIPS; requires voltage ≥2.7 V and ambient ≤125 °C; CSEc/EEPROM access disabled at this speed. |
| Flash Memory | 2 MB program flash with ECC - supports robust code storage and error detection/correction for automotive ASIL-B applications. |
| SRAM | 256 KB on-chip SRAM with ECC - provides fault-tolerant data workspace for safety-critical runtime variables and stack. |
| Operating Temperature | -40 °C to +125 °C ambient (M-grade) - qualified for under-hood automotive environments per AEC-Q100 Grade 1. |
| I/O Count | Up to 156 GPIO pins - supports flexible peripheral multiplexing including LIN, CAN-FD, LPI2C, and FlexIO protocol emulation. |
| Security Engine | Cryptographic Services Engine (CSEc) - implements SHE-compliant AES, SHA, RNG, and key management; requires RUN mode (80 MHz) execution. |
Pinout & Package
FS32K144HRT0MMHR is packaged in a 144-pin LQFP (Low-Profile Quad Flat Package) with 0.5 mm pitch, RoHS-compliant, moisture sensitivity level 3. Pinout conforms to S32K14x family standard layout; full signal assignment is defined in the S32K1xx Reference Manual IO Signal Description sheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Power and analog reference supply | Must be decoupled locally; VDD and VDDA tied together on PCB; VREFH ≤ VDDA + 0.1 V ensures ADC accuracy. |
| RESET_B | Active-low reset input | Asynchronous, low-voltage detect (LVD)-enabled reset; initiates cold boot or recovery from fault conditions. |
| SWD_CLK / SWD_IO | Serial Wire Debug interface | Two-pin debug port supporting JTAG/SWD protocols; enables non-intrusive debugging, trace, and flash programming. |
| PTA0–PTA31, PTB0–PTB31, etc. | GPIO with multiplexed peripherals | Configurable as digital I/O, ADC inputs, UART/LIN/CAN signals, or FlexIO-emulated interfaces - mapped via SIM_SCGC registers. |
| CLKOUT, RTC_CLKIN | Clock output/input terminals | RTC_CLKIN accepts 32.768 kHz crystal; CLKOUT provides selectable system clock derivative for external timing validation. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Ready Architecture | System MPU at crossbar level enforces memory region access rights for CPU/DMA/Ethernet; ECC on flash/SRAM; CRC module and dual watchdogs (WDOG + EWM). |
| Flexible Power Modes | Five distinct low-power states (HSRUN/RUN/STOP/VLPR/VLPS); VLPS achieves sub-μA current draw while retaining RAM and RTC state. |
| Dual CAN-FD Support | Two independent FlexCAN modules, each supporting ISO 11898-1 CAN FD up to 5 Mbps - enables high-bandwidth vehicle network backbone and domain controller communication. |
| ADC Performance | Two 12-bit SAR ADCs, each with up to 32 channels and 1 Msps sampling rate - supports simultaneous motor phase current sensing and battery cell monitoring. |
| FlexIO Protocol Emulation | 8-pin configurable module supporting UART, SPI, I2C, I2S, LIN, PWM, and custom protocols - reduces BOM count by replacing discrete interface ICs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K144HRT0VLHR | V-grade (-40 °C to +105 °C), same 144-pin LQFP package and 2 MB flash; lacks M-grade thermal qualification. | Suitable for cabin electronics (e.g., HVAC control) where ambient temperature stays below 105 °C. | Select when cost-sensitive designs do not require under-hood thermal rating; identical pinout and firmware compatibility. |
| FS32K146HRT0MLHR | M-grade, 144-pin LQFP, but with 1 MB flash and 384 KB SRAM; adds third FlexCAN module and second Ethernet MAC. | Targeted at higher-integration gateways needing redundant Ethernet or additional CAN FD channels. | Choose when extra communication bandwidth or memory headroom justifies trade-off against FS32K144HRT0MMHR's optimized BOM cost. |
Compared with FS32K144HRT0MMHR, FS32K144HRT0VLHR offers identical functionality at lower thermal grade for cost-sensitive cabin applications, while FS32K146HRT0MLHR extends connectivity and memory for gateway-class workloads - neither is pin-compatible drop-in replacement due to differing peripheral enablement and memory mapping.

FAQ
What is the maximum operating frequency of the FS32K144HRT0MMHR and under what conditions?
The FS32K144HRT0MMHR achieves up to 112 MHz in HSRUN mode, conditioned on supply voltage ≥2.7 V and ambient temperature ≤125 °C. However, CSEc cryptographic operations and EEPROM writes must be executed in RUN mode (80 MHz) - the device automatically triggers error flags if attempted at 112 MHz. This behavior is documented in NXP's S32K1xx datasheet Rev. 15 Section 1.1 and Figure 3 feature comparison.
Does the FS32K144HRT0MMHR support CAN-FD, and how many instances are available?
Yes, the FS32K144HRT0MMHR integrates three FlexCAN modules, all supporting CAN-FD per ISO 11898-1 with data rates up to 5 Mbps. The "F" in ordering option Y (e.g., "F" in FS32K144HRT0MMHR) explicitly denotes CAN-FD capability. All three modules are accessible in the 144-pin LQFP package, with pin assignments confirmed in the S32K1xx Reference Manual IO Signal Description sheet.
What safety certifications apply to the FS32K144HRT0MMHR?
The FS32K144HRT0MMHR is qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C) and supports ASIL-B development per ISO 26262. Its safety mechanisms include ECC on flash and SRAM, system-level MPU enforcing crossbar master access rights, dual watchdogs (WDOG and EWM), CRC engine, and lockstep-capable peripherals - all detailed in the S32K1xx datasheet Sections 1.1 and 3.1.
How much on-chip memory does the FS32K144HRT0MMHR provide, and what types are included?
The FS32K144HRT0MMHR includes 2 MB of program flash memory with ECC, 256 KB of SRAM with ECC, 64 KB of FlexNVM for data flash/EEPROM emulation, and 4 KB of FlexRAM usable as SRAM or EEPROM emulation. These allocations are fixed per the S32K144 variant definition in the S32K1xx datasheet Figure 3 and Section 1.1 "Memory and memory interfaces".
Is the FS32K144HRT0MMHR pin-compatible with other S32K1xx devices in the same package?
Yes - all S32K1xx devices sharing the 144-pin LQFP package (e.g., FS32K144HRT0VLHR, FS32K146HRT0MLHR) are pin-to-pin compatible per NXP's datasheet Section 3.1: "All devices which share a common package are pin-to-pin compatible." Signal multiplexing differs by variant, but physical pin functions and electrical characteristics remain consistent across the family.
