Product details
Overview
FS32K148URT0VLQT from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller designed for safety-critical body electronics and powertrain control. It operates at up to 112 MHz in HSRUN mode, features 2 MB ECC-protected flash, 256 KB ECC SRAM, and supports -40 °C to 105 °C ambient operation in a 100-pin LQFP package. It integrates FlexCAN with optional CAN-FD, CSEc security engine, and IEEE 1588 Ethernet MAC.
For engineers reviewing the FS32K148URT0VLQT datasheet, FS32K148URT0VLQT pinout, FS32K148URT0VLQT application, or FS32K148URT0VLQT equivalent, key selection considerations include ASIL-B capable safety architecture, dual-core debug support (SWD/JTAG/ITM/TPIU), HSRUN/RUN power mode trade-offs for CSEc/EEPROM operations, and 100-pin LQFP I/O mapping for automotive gateway or ECU designs.
Technical Context
The FS32K148URT0VLQT implements a dual-core debug architecture with Arm Cortex-M4F core (Armv7, Thumb-2 ISA) and integrated FPU, DSP, and NVIC. Its clock system includes SOSC (4–40 MHz), FIRC (48 MHz), SPLL (up to 112 MHz), and LPO (128 kHz), enabling precise timing control across HSRUN, RUN, STOP, VLPR, and VLPS modes.
Memory subsystem comprises 2 MB program flash with ECC, 64 KB FlexNVM with EEPROM emulation, 256 KB SRAM with ECC, and 4 KB FlexRAM configurable as SRAM or EEPROM. Safety features include System MPU (crossbar-level memory protection), CRC module, WDOG/EWM, and CSEc compliant with SHE specification - all validated for ASIL-B functional safety applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M4F with FPU, DSP, and NVIC - enables real-time signal processing and deterministic interrupt handling in automotive control loops. |
| Max Clock Frequency | 112 MHz (HSRUN mode); 80 MHz (RUN mode) - higher frequency enables faster control cycle execution but requires mode switch for CSEc/EEPROM access. |
| Flash Memory | 2 MB with ECC - ensures data integrity and fault tolerance for boot code and application firmware in harsh automotive environments. |
| SRAM | 256 KB with ECC - provides robust working memory for safety-critical variables and stack operations with error detection/correction. |

| Temperature Range | -40 °C to 105 °C (ambient) - qualified for under-hood and body control unit deployment per V-grade specification. |
| Package | 100-pin LQFP - provides 81 GPIOs and full peripheral routing for CAN-FD, Ethernet, LPUART, LPSPI, and ADC interfaces. |
| Safety Certification | ASIL-B capable with System MPU, CRC, WDOG, EWM, and CSEc - meets ISO 26262 requirements for automotive safety mechanisms. |
Pinout & Package
FS32K148URT0VLQT is housed in a 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch) package with exposed thermal pad. Pin functions are defined per the S32K1xx Reference Manual IO Signal Description sheet; pin count and I/O availability align with the 100-pin LQFP variant supporting up to 81 GPIOs.
| 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 stability. |
| RESET_B | Active-low reset input | Asynchronous reset assertion clears CPU state and initiates boot sequence from flash or ROM. |
| SWD_CLK, SWD_IO | Serial Wire Debug interface | Enables non-intrusive debugging, flash programming, and trace via ARM CoreSight-compatible tools. |
| CAN0_TX, CAN0_RX | FlexCAN channel 0 differential I/O | Supports CAN 2.0B or CAN-FD (with external transceiver); requires termination and common-mode filtering. |
| ENET_RMII_RXD0–3, TXD0–1 | Ethernet RMII physical layer interface | Direct connection to IEEE 802.3-compliant PHY; supports 10/100 Mbps with IEEE 1588 timestamping. |
| ADC0_SE0–31 | Analog input channels for 12-bit SAR ADC | Up to 32 single-ended inputs per ADC module; supports hardware-triggered conversions and DMA transfer. |
Key Features
| Feature | Design Value |
|---|---|
| FlexCAN with CAN-FD | Three independent FlexCAN modules; CAN-FD enabled on all three - supports higher data rates (up to 5 Mbps) and extended payload (64 bytes) for automotive domain controllers. |

| QuadSPI with HyperBus™ | External memory interface supporting x4 DDR HyperBus protocol - enables fast execution from external NOR flash or PSRAM with minimal latency penalty. |
| System MPU | NXP's crossbar-level memory protection unit - enforces access rights per master (CPU, DMA, Ethernet), preventing unauthorized memory access critical for ASIL-B compliance. |
| Low-Power Timer Suite | LPIT (4-channel), LPTMR, PDB, and RTC - provides flexible wake-up sources, time-stamped event capture, and deterministic timing for sleep/wake transitions. |
| Debug & Trace Infrastructure | SWJ-DP, ITM, DWT, TPIU, MTB - delivers real-time instruction trace, data watchpoints, and streaming trace output for complex automotive software validation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K146HRT0VLQT | 1 MB flash, 192 KB SRAM, no Ethernet or SAI - lacks IEEE 1588 MAC and audio interfaces. | Suitable for cost-sensitive body control units without Ethernet backhaul or audio processing needs. | Select when Ethernet and SAI are unnecessary and BOM cost optimization is prioritized over future scalability. |
| S32K148HRT0MLQT | Same core/peripherals but M-grade (-40 °C to 125 °C) and 144-pin LQFP - higher temperature rating and 128 GPIOs. | Required for under-hood applications exceeding 105 °C ambient, such as engine control or transmission modules. | Choose for thermal environments beyond V-grade limits; note PCB redesign needed for 144-pin footprint. |
Compared with FS32K148URT0VLQT, S32K146HRT0VLQT reduces memory and connectivity for lower-cost BCMs, while S32K148HRT0MLQT extends thermal capability and I/O count at the expense of larger package and layout changes - neither is pin-compatible, requiring board revision for migration.

FAQ
What is the maximum operating frequency of the FS32K148URT0VLQT and under what conditions?
The FS32K148URT0VLQT achieves up to 112 MHz in HSRUN mode, but this frequency requires VDD ≥ 2.97 V when the SPLL is active. At lower supply voltages (≥2.7 V), operation is limited to 48 MHz using the FIRC oscillator. The device must drop to 80 MHz RUN mode to execute CSEc cryptographic operations or FlexNVM EEPROM emulation - attempting these in HSRUN triggers error flags.
Does the FS32K148URT0VLQT support CAN-FD, and how many instances are available?
Yes, the FS32K148URT0VLQT integrates three independent FlexCAN modules, all supporting CAN-FD per ISO 11898-1:2015. Each module supports bit rates up to 5 Mbps and payloads up to 64 bytes. CAN-FD functionality is enabled by default and does not require external configuration beyond transceiver selection and bus termination.
What safety features does the FS32K148URT0VLQT include for ASIL-B compliance?
The FS32K148URT0VLQT includes System MPU (crossbar-level memory protection), CRC module, internal watchdog (WDOG), external watchdog monitor (EWM), ECC on flash and SRAM, and CSEc for secure boot and key management - all documented in NXP's ISO 26262 ASIL-B ready safety manual. These features collectively support diagnostic coverage targets required for ASIL-B decomposition.
Can the FS32K148URT0VLQT execute code from external memory, and which interface is used?
Yes, the FS32K148URT0VLQT supports external memory execution via its QuadSPI interface with HyperBus™ protocol compatibility. This allows XIP (execute-in-place) from external NOR flash or PSRAM, reducing internal flash pressure and enabling modular firmware updates. The interface operates in DDR mode with up to 133 MHz clock rate and supports memory-mapped addressing.
What debug and trace capabilities are built into the FS32K148URT0VLQT?
The FS32K148URT0VLQT integrates Serial Wire JTAG Debug Port (SWJ-DP), Instrumentation Trace Macrocell (ITM), Data Watchpoint and Trace (DWT), Test Port Interface Unit (TPIU), and 1 KB Micro Trace Buffer (MTB). These enable real-time instruction trace, data watchpoints, streaming SWO output, and non-intrusive debugging - fully compatible with NXP S32DS, IAR EWARM, and Lauterbach TRACE32 toolchains.
