Pinout & Package
FS32K148HNT0VLUT is housed in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch), RoHS-compliant and moisture-sensitive level 3. Pin assignment follows NXP's standardized S32K14x 100-pin LQFP layout with dedicated power/ground pairs, configurable GPIOs (up to 156 total), and dedicated high-speed interfaces (Ethernet RMII, QuadSPI, CAN transceiver pins).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Analog & digital supply inputs | Must be decoupled locally; VDDA and VDD require ≤0.1 V differential to ensure ADC accuracy and I/O stability. |
| PTA0–PTA31, PTB0–PTB31, etc. | Configurable GPIOs | 156 total pins support interrupt, DMA, and peripheral multiplexing; 100-pin LQFP exposes 81 GPIOs with flexible ALT function routing via TRGMUX. |
| CAN0_TX/CAN0_RX, CAN1_TX/CAN1_RX, CAN2_TX/CAN2_RX | FlexCAN differential signal pairs | Support CAN-FD up to 5 Mbps; require external transceivers and termination; mapped to dedicated pins with internal loopback test capability. |
| ENET0_RXD0–ENET0_RXD3, ENET0_TXD0–ENET0_TXD3, ENET0_REF_CLK | Ethernet MAC physical interface | RMII-compliant; supports IEEE 1588 timestamping; requires 50 Ω impedance-controlled traces and external PHY for full PHY layer implementation. |
| QSPI0_SCK, QSPI0_DATA0–QSPI0_DATA3 | QuadSPI bus signals | Enables HyperBus™-compatible external memory expansion; not supported on 100-pin LQFP per Figure 3 footnote. |
| SWD_DIO, SWD_CLK | Serial Wire Debug interface | 2-pin debug port supporting full JTAG/SWD functionality, trace (ITM/TPIU), and flash programming at up to 25 MHz SWD_CLK. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Capable Architecture | System MPU enforces crossbar-level memory access rights for all masters (CPU, DMA, Ethernet); combined with ECC, CRC, and dual-watchdog (WDOG + EWM) for fault containment. |
| Flexible Power Management | Five distinct low-power modes (HSRUN/RUN/STOP/VLPR/VLPS) with sub-μA deep-sleep current; clock gating per peripheral enables granular energy optimization in body electronics. |
| Dual-Core Safety Monitor | M0+ core independently verifies M4F execution flow and memory integrity using CRC and signature checks-enabling runtime safety checking without M4F overhead. |
| Secure Boot & Firmware Updates | CSEc performs authenticated boot and encrypted OTA updates using hardware-accelerated AES-256 and SHA-256; keys stored in protected OTP memory with anti-tamper logic. |
| Automotive Communication Suite | Three CAN-FD controllers + LIN-capable LPUART + Ethernet enable hierarchical vehicle networks-from sensor nodes (LIN) to domain controllers (CAN-FD) to gateway/ADAS (Ethernet). |
| High-Resolution Timing | Eight FlexTimer modules (64 PWM/IC/OC channels), LPIT (4-channel), RTC, and PDB provide synchronized timing for motor control, lighting PWM, and wake-up event sequencing. |
Applications
| Body Control Module (BCM) | Advanced Lighting Control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K146HFT0VLUT | 1 MB flash, 192 KB SRAM, no Ethernet MAC, 2× FlexCAN (CAN-FD), same 100-pin LQFP and -40°C to 105°C grade. | Lacks Ethernet and one FlexCAN channel; suitable for non-gateway body ECUs where network bandwidth is lower. | Select when Ethernet and third CAN channel are unnecessary-reduces BOM cost while retaining identical pinout and software compatibility. |
| S32K148HRT0VLUT | Same 2 MB flash, 256 KB SRAM, and peripherals, but rated for -40°C to 125°C (M-grade) and uses 80 MHz RUN mode max frequency instead of 112 MHz HSRUN. | Targeted for higher-temperature under-hood applications (e.g., engine control adjuncts); trades peak performance for extended thermal range. | Choose for environments exceeding 105°C ambient-requires software adaptation to avoid HSRUN mode usage and CSEc/EEPROM operations during high-frequency execution. |
Compared with FS32K148HNT0VLUT, S32K146HFT0VLUT reduces memory and connectivity for cost-sensitive body nodes, while S32K148HRT0VLUT shifts thermal capability toward under-hood use at the expense of peak 112 MHz performance-neither is pin-compatible drop-in replacements without design review.

FAQ
What is the maximum operating frequency of the FS32K148HNT0VLUT?
The FS32K148HNT0VLUT operates at up to 112 MHz in HSRUN mode and 80 MHz in RUN mode. This dual-frequency capability enables high-performance computation during active phases while maintaining energy efficiency in lower-power states. The 112 MHz rating is validated across the full -40°C to 105°C ambient temperature range specified for this V-grade part.
Does the FS32K148HNT0VLUT support CAN-FD?
Yes, the FS32K148HNT0VLUT integrates three FlexCAN modules, each supporting CAN-FD protocol with data rates up to 5 Mbps. All three CAN controllers are accessible on the 100-pin LQFP package, with dedicated TX/RX pins and built-in message RAM, loopback testing, and error counters-enabling robust multi-bus vehicle networking.
What security features does the FS32K148HNT0VLUT include?
The FS32K148HNT0VLUT includes the Cryptographic Services Engine (CSEc), compliant with the SHE specification, supporting AES-128/256, SHA-256, RSA, and ECC. It also provides 128-bit unique ID, ECC on flash and SRAM, System MPU for memory protection, CRC module, and dual watchdogs (WDOG and EWM) for comprehensive hardware-enforced security.
Is Ethernet functionality available on the FS32K148HNT0VLUT in the 100-pin LQFP package?
Yes, the FS32K148HNT0VLUT includes a 10/100 Mbps Ethernet MAC with IEEE 1588 timestamping support, and this feature is fully enabled in the 100-pin LQFP package. However, external PHY and proper PCB layout (impedance-controlled RMII traces, 50 Ω matching) are required to implement the full Ethernet physical layer.
Can the FS32K148HNT0VLUT execute CSEc or EEPROM operations in HSRUN mode?
No. The FS32K148HNT0VLUT will trigger error flags if CSEc cryptographic operations or EEPROM writes/erases are attempted in HSRUN mode (112 MHz). Per NXP documentation, the device must switch to RUN mode (80 MHz) to safely execute these functions-this is a hard architectural constraint, not a configuration option.
