Product details
Overview
FS32K148UIT0VLQT from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with 2 MB flash, 256 KB SRAM (both with ECC), 112 MHz HSRUN operation, and integrated CSEc security engine. It supports CAN-FD, FlexCAN, Ethernet (10/100 Mbps with IEEE 1588), and operates across -40 °C to +105 °C for body control modules and ADAS domain controllers.
For engineers reviewing the FS32K148UIT0VLQT datasheet, FS32K148UIT0VLQT pinout, FS32K148UIT0VLQT application, or FS32K148UIT0VLQT equivalent, this page delivers verified technical context, package mapping to 100-pin LQFP, real-world timing constraints (HSRUN/RUN mode switching for EEPROM/CSEc), safety-critical peripheral configuration (ASIL-B capable), and validated alternative part selection guidance.
Technical Context
The FS32K148UIT0VLQT implements a dual-core architecture with Arm Cortex-M4F (112 MHz HSRUN / 80 MHz RUN) and optional M0+ co-processor support, featuring integrated DSP, single-precision FPU, and configurable NVIC. Its memory subsystem includes 2 MB program flash with ECC, 64 KB FlexNVM for EEPROM emulation, and 256 KB SRAM with ECC - all protected by NXP's system MPU at the crossbar switch level.
Peripherals are optimized for automotive functional safety: three FlexCAN modules (all with CAN-FD), one 10/100 Mbps Ethernet MAC with IEEE 1588 timestamping, eight FlexTimer modules (64 PWM/IC/OC channels), and CSEc cryptographic engine compliant with SHE specification. Power management supports five modes (HSRUN, RUN, STOP, VLPR, VLPS), with mandatory mode transition from HSRUN to RUN (80 MHz) for CSEc execution or EEPROM write/erase operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M4F with DSP and single-precision FPU; enables real-time signal processing and floating-point math in motor control and sensor fusion. |

| Memory | 2 MB flash (ECC-protected), 256 KB SRAM (ECC-protected), 64 KB FlexNVM (EEPROM emulation); ensures data integrity in safety-critical storage. |
| Temperature Range | -40 °C to +105 °C ambient (V-grade); qualified for under-hood automotive applications requiring extended thermal robustness. |
| Security | Cryptographic Services Engine (CSEc) implementing SHE-compliant functions; requires RUN mode (80 MHz) for secure boot and key management. |

Pinout & Package
FS32K148UIT0VLQT is housed in a 100-pin LQFP package (14 × 14 mm, 0.5 mm pitch), RoHS-compliant and automotive-qualified. Pinout follows S32K14x family standardization, with dedicated VDD/VSS pairs per power domain, separate analog/digital supplies (VDDA/VDD), and dedicated debug (SWD/JTAG) and clock (SOSC/FIRC/SIRC/LPO) pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dedicated pairs per I/O bank and analog domain; decoupling required per AN5032 for ADC stability. |
| VDDA, VREFH, VREFL | Analog reference supply | VDDA must be shorted to VDD on PCB; VREFH ≤ VDDA + 0.1 V ensures 12-bit ADC accuracy across temperature. |

| CAN0_TX, CAN0_RX | FlexCAN channel 0 differential signals | Direct connection to external CAN transceiver; supports ISO 11898-1 CAN-FD up to 5 Mbps with built-in loopback test mode. |
| ENET_RMII_RXD0–RXD1, TXD0–TXD1, REF_CLK | Ethernet RMII physical interface | Enables 10/100 Mbps communication with IEEE 1588 timestamping; REF_CLK sourced internally or externally at 50 MHz. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Capable Architecture | System MPU enforces memory access rights per master (core/DMA/Ethernet) at crossbar level - critical for ISO 26262 compliance in ECU partitioning. |
| Functional Safety Peripherals | Dual watchdogs (WDOG + EWM), CRC module, ECC on flash/SRAM, and lockstep-capable FlexTimers enable diagnostic coverage for ASIL-B systems. |
| Low-Power Flexibility | Five power modes (HSRUN/RUN/STOP/VLPR/VLPS) with configurable clock gating; LPIT and LPTMR support wake-up from deep sleep with sub-millisecond latency. |
| Flexible Communication Stack | Three FlexCAN (CAN-FD), three LPSPI, two LPI2C, three LPUART/LIN, FlexIO (UART/I2C/SPI/PWM emulation), and Ethernet - eliminates need for companion protocol ICs. |
| Secure Boot & Key Management | CSEc engine performs AES-128/256, SHA-256, RNG, and secure key storage; requires RUN mode (80 MHz) execution - design must sequence mode transitions. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K146HFT0VLQT | 1 MB flash, 192 KB SRAM, no Ethernet or SAI; same 100-pin LQFP, identical HSRUN/RUN modes and CSEc implementation. | Lacks IEEE 1588 Ethernet and SAI - unsuitable for time-synchronized ADAS or audio gateway use cases. | Select when Ethernet/SAI are unnecessary and BOM cost reduction is prioritized without sacrificing CAN-FD count or safety features. |
| S32K148HFT0VLQT | Same 2 MB flash, 256 KB SRAM, and peripherals, but rated for 80 MHz only (no HSRUN mode); identical package and pinout. | Cannot execute performance-critical algorithms at 112 MHz - limits real-time compute headroom for sensor fusion or motor control. | Choose for thermally constrained environments where 80 MHz suffices and guaranteed HSRUN operation is not required. |
Compared with FS32K148UIT0VLQT, S32K146HFT0VLQT reduces memory and networking capability for cost-sensitive BCMs, while S32K148HFT0VLQT trades peak performance for thermal margin - both retain pin compatibility and safety architecture but constrain distinct design axes: feature set vs. clock speed.

FAQ
What is the maximum operating frequency of the FS32K148UIT0VLQT and under what conditions?
The FS32K148UIT0VLQT achieves 112 MHz in HSRUN mode, but only when supplied within 2.97–5.5 V and ambient temperature is maintained at -40 °C to +105 °C. Operation above 2.97 V is mandatory when using the SPLL - below that voltage, the device defaults to 80 MHz RUN mode. This constraint directly impacts real-time compute throughput in motor control loops.
Does the FS32K148UIT0VLQT support CAN-FD, and how many instances are available?
Yes, the FS32K148UIT0VLQT integrates three independent FlexCAN modules, each supporting CAN-FD per ISO 11898-1 with data rates up to 5 Mbps. All three modules are accessible in the 100-pin LQFP package, with dedicated TX/RX pins routed to separate I/O banks - enabling simultaneous high-speed communication with radar, ADAS domain, and gateway nodes.
Why does CSEc execution require switching from HSRUN to RUN mode on the FS32K148UIT0VLQT?
CSEc (Cryptographic Services Engine) execution and EEPROM write/erase operations are explicitly prohibited in HSRUN mode (112 MHz) per NXP documentation - attempting either triggers error flags. The FS32K148UIT0VLQT must transition to RUN mode (80 MHz) to perform secure boot, key derivation, or flash updates. This is a hard architectural constraint, not a software limitation.
What package type and pin count does the FS32K148UIT0VLQT use, and is it pin-compatible with other S32K14x devices?
The FS32K148UIT0VLQT uses a 100-pin LQFP package (14 × 14 mm, 0.5 mm pitch). It is fully pin-to-pin compatible with other S32K14x devices in the same package variant - including S32K146 and S32K144 - enabling hardware reuse across memory and peripheral variants without PCB redesign.
How does the FS32K148UIT0VLQT implement functional safety for ASIL-B compliance?
The FS32K148UIT0VLQT achieves ASIL-B capability through hardware-enforced mechanisms: system MPU controlling crossbar-level memory access per master (core/DMA/Ethernet), ECC on 2 MB flash and 256 KB SRAM, dual watchdogs (WDOG + EWM), CRC acceleration unit, and lockstep-capable FlexTimer modules. These are documented in the S32K1xx Functional Safety Manual and certified per ISO 26262.
