It features dual 12-bit ADCs (32-channel total), three FlexCAN modules (CAN-FD capable), Ethernet MAC (10/100 Mbps with IEEE 1588), and supports ASIL-B functional safety in automotive body control modules.
For engineers reviewing the FS32K148UJT0VLUT datasheet, FS32K148UJT0VLUT pinout, FS32K148UJT0VLUT application, or FS32K148UJT0VLUT equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use-value analysis for automotive ECU designs, and validated alternative options aligned to S32K148's 100-pin LQFP, -40°C to 105°C, and 112 MHz HSRUN configuration.
Technical Context
The FS32K148UJT0VLUT implements a dual-core execution environment via Arm Cortex-M4F (primary) and M0+ (co-processor), enabling concurrent real-time control and safety monitoring. Its clock architecture integrates SPLL (up to 112 MHz), FIRC (48 MHz), SIRC (8 MHz), and LPO (128 kHz), with dynamic mode switching between HSRUN (112 MHz), RUN (80 MHz), STOP, VLPR, and VLPS.
Memory subsystem includes 2 MB program flash with ECC, 64 KB FlexNVM for EEPROM emulation, 256 KB SRAM with ECC, and 4 KB FlexRAM configurable as SRAM or EEPROM. Safety mechanisms include System MPU (crossbar-level memory protection), CRC module, WDOG/EWM, and CSEc cryptographic engine compliant with SHE specification - all validated for ASIL-B systems.

Pinout & Package
FS32K148UJT0VLUT is housed in a 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch) package, pin-compatible with other S32K14x devices in the same footprint. This package supports full peripheral access including Ethernet RMII, CAN FD transceivers, and high-speed ADC sampling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Power supply and analog reference | Must be decoupled locally; VDD/VDDA differential ≤ ±0.1 V ensures ADC accuracy and flash reliability. |
| PTA0–PTA31, PTB0–PTB31, PTC0–PTC31, PTD0–PTD15, PTE0–PTE15 | GPIO with interrupt capability | 156 total GPIOs support multiplexed functions (e.g., UART, SPI, CAN, PWM); 100-pin LQFP exposes 81 pins usable as GPIO. |
| ENET0_RXD0/1, ENET0_TXD0/1, ENET0_CRS_DV, ENET0_TX_EN, ENET0_REF_CLK | Ethernet physical interface | Supports RMII timing at 50 MHz; requires 50 Ω impedance-controlled traces and 50 ppm crystal for IEEE 1588 timestamping. |
| CAN0_TX/RX, CAN1_TX/RX, CAN2_TX/RX | CAN-FD transceiver interface | Each pair supports ISO 11898-1 up to 5 Mbps; internal loopback and bus-off recovery reduce external component count. |
| ADC0_SE0–ADC0_SE31, ADC1_SE0–ADC1_SE31 | Analog input channels | 32 dedicated inputs per ADC module; simultaneous sampling across both ADCs enables motor phase current sensing. |
| SWD_CLK, SWD_DIO, RESET_b | Debug and reset interface | Serial Wire Debug (SWD) enables non-intrusive trace, flash patching, and secure debug authentication via CSEc. |
Key Features
| Feature | Design Value |
|---|---|
| HSRUN Mode at 112 MHz | Enables real-time deterministic response for motor control loops while maintaining full peripheral availability except CSEc/EEPROM operations. |
| FlexNVM with EEPROM Emulation | 64 KB data flash + 4 KB FlexRAM provide wear-leveling and atomic write/erase for calibration data storage without external EEPROM. |
| System MPU (Crossbar-Level) | Prevents DMA or core access violations across memory regions - critical for ASIL-B partitioning of safety-critical and non-safety software. |
| QuadSPI with HyperBus™ Support | Enables external XIP execution from NOR flash at up to 133 MHz, reducing boot time and BOM cost vs. parallel NOR interfaces. |
| FlexIO Module | Configurable as UART, I²C, SPI, I²S, LIN, or PWM - replaces discrete protocol bridge ICs in lighting, HVAC, and sensor interface sub-systems. |

FAQ
What is the maximum operating frequency of the FS32K148UJT0VLUT and under what conditions?
The FS32K148UJT0VLUT operates at up to 112 MHz in HSRUN mode, guaranteed across -40°C to 105°C ambient temperature and 2.97 V to 5.5 V supply voltage. This frequency requires the System PLL (SPLL) to be enabled and excludes CSEc or EEPROM operations, which must execute in RUN mode (80 MHz) per NXP documentation. The 112 MHz rating is validated for real-time control tasks such as motor FOC and sensor sampling.
Does the FS32K148UJT0VLUT support CAN-FD, and how many instances are available?
Yes, the FS32K148UJT0VLUT 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 CAN transceiver interfaces - enabling concurrent communication on powertrain, chassis, and body networks without arbitration bottlenecks.
What safety certifications apply to the FS32K148UJT0VLUT?
The FS32K148UJT0VLUT is qualified for ASIL-B according to ISO 26262:2018, with built-in safety mechanisms including ECC on flash/SRAM, System MPU for memory partitioning, CRC module, dual watchdogs (WDOG and EWM), and lockstep-capable peripherals. Its safety manual and FMEDA report are provided by NXP, and the device supports diagnostic coverage for fault detection in both HSRUN and RUN modes.
Can the FS32K148UJT0VLUT execute secure boot and cryptographic operations simultaneously with real-time control tasks?
No - CSEc cryptographic operations (including secure boot validation) cannot execute concurrently with HSRUN mode (112 MHz). The FS32K148UJT0VLUT must transition to RUN mode (80 MHz) to perform CSEc functions or EEPROM writes/erases. This mode switch is managed by the Power Management Controller (PMC) and is transparent to application software via HAL APIs in the S32 SDK.
What is the pin-compatible upgrade path from the FS32K148UJT0VLUT?
The FS32K148UJT0VLUT is pin-compatible with all S32K14x devices in the 100-pin LQFP package, including FS32K146UJT0VLUT and FS32K144UJT0VLUT. Migration requires only flash/SRAM size and peripheral enablement adjustments in software; no PCB redesign is needed. However, Ethernet and SAI functionality present in FS32K148UJT0VLUT are not available on lower variants.
