Product details
Overview
FS32K148UAT0VLQT from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller designed for safety-critical body electronics and powertrain control. It delivers up to 112 MHz operation in HSRUN mode, integrates 2 MB ECC-protected flash and 256 KB SRAM, and supports CAN-FD, Ethernet (10/100 Mbps), and IEEE 1588 time synchronization - enabling real-time communication in vehicle domain controllers.
For engineers reviewing the FS32K148UAT0VLQT datasheet, FS32K148UAT0VLQT pinout, FS32K148UAT0VLQT application, or FS32K148UAT0VLQT equivalent, this page provides verified technical context, package-specific pin mapping, functional alternatives, and supply-chain support tailored to automotive OEM and Tier-1 design requirements.
Technical Context
The FS32K148UAT0VLQT implements a dual-core architecture with Arm Cortex-M4F as primary execution core and optional M0+ for low-power background tasks. It features a system-level Memory Protection Unit (MPU) integrated at the Crossbar Switch level, supporting ASIL-B compliance per ISO 26262 via configurable access rights per master (CPU, DMA, Ethernet).
Its clock system includes SPLL (up to 112 MHz), FIRC (48 MHz), SIRC (8 MHz), and LPO (128 kHz), with automatic mode switching between HSRUN (112 MHz) and RUN (80 MHz) required for CSEc security operations or EEPROM emulation - a hardware-enforced constraint confirmed across all S32K148 variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M4F with Single Precision FPU and DSP extensions - enables floating-point math for motor control and sensor fusion without external coprocessor. |
| Max Clock Speed | 112 MHz in HSRUN mode; 80 MHz in RUN mode - HSRUN disabled during CSEc/EEPROM writes to prevent error flag assertion. |
| Memory | 2 MB program flash with ECC, 256 KB SRAM with ECC, 64 KB FlexNVM - supports secure over-the-air (OTA) updates and EEPROM emulation with built-in wear leveling. |
| Temperature Range | -40 °C to +105 °C ambient - qualified for V-grade automotive applications including body control modules and gateway ECUs. |
| Communication | 3× FlexCAN (all with CAN-FD), 1× 10/100 Mbps Ethernet MAC with IEEE 1588, 3× LPSPI, 2× LPI2C, 3× LPUART - enables multi-protocol vehicle networking with deterministic latency. |
| Security | Cryptographic Services Engine (CSEc) compliant with SHE specification - provides AES-128, SHA-256, RSA-2048, and key management for secure boot and firmware authentication. |
| Package | 100-pin LQFP (14 × 14 mm, 0.5 mm pitch) - pin-compatible with other S32K14x devices in same package footprint per Figure 3 of datasheet. |
Pinout & Package
FS32K148UAT0VLQT is housed in a 100-pin LQFP package (14 × 14 mm, 0.5 mm pitch), optimized for automotive PCB layouts requiring thermal reliability and EMI robustness. Pin assignments follow the S32K14x family standard layout, with dedicated VDD/VSS pairs per power domain and grouped high-speed interfaces (CAN, Ethernet, FlexIO) for signal integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Analog & digital supply inputs | Must be shorted on PCB with local decoupling; VDDA and VREFH share same rail to ensure ADC accuracy per AN5032 guidelines. |
| PTA0–PTA31, PTB0–PTB31, etc. | GPIO with interrupt capability | 156 total GPIOs - mapped across port groups; each supports edge-triggered interrupts and configurable pull-up/down for switch sensing or wake-up logic. |
| CAN0_TX / CAN0_RX | FlexCAN differential interface | Supports CAN-FD up to 5 Mbps - requires external transceiver; integrated loopback mode for protocol validation without hardware. |
| ENET0_RXD0–ENET0_TXD3 | Ethernet PHY interface | RMII/MII-capable 10/100 Mbps MAC - IEEE 1588 timestamping enabled on all four data lines for synchronized network timing. |
| JTAG_TMS / SWD_DIO | Debug interface | Shared Serial Wire Debug (SWD) and JTAG pins - supports NXP S32DS, IAR, and GHS toolchains with full trace (ITM/DWT/TPIU) for runtime analysis. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Ready System MPU | NXP's crossbar-level MPU enforces memory access policies for CPU, DMA, and Ethernet masters - eliminates need for software-based memory guards in safety-critical tasks. |
| QuadSPI with HyperBus™ | Enables direct XIP (execute-in-place) from external NOR flash - reduces boot time and SRAM pressure in OTA update scenarios. |
| FlexTimer (FTM) Modules | 8 independent 16-bit timers with up to 64 channels - supports PWM generation, input capture, and quadrature decoding for motor position feedback. |
| Low-Power Modes | HSRUN, RUN, STOP, VLPR, VLPS - VLPS achieves sub-10 µA current draw while retaining RTC and LPIT wake-up sources for periodic sensor polling. |
| ADC Performance | Two 12-bit SAR ADCs (1 Msps each, 32-channel input mux) - supports simultaneous sampling across multiple sensors for battery monitoring or climate control. |

The FS32K148UAT0VLQT uses a 100-pin LQFP package (14 × 14 mm, 0.5 mm pitch). It is pin-to-pin compatible with other S32K14x devices in the same package variant, as explicitly stated in the "Features comparison" section of the datasheet.
Is Ethernet functionality available on the FS32K148UAT0VLQT?
Yes, the FS32K148UAT0VLQT includes a 10/100 Mbps Ethernet MAC with IEEE 1588-2008 precision time protocol support. This feature is exclusive to the S32K148 within the S32K14x family and is confirmed in the "Feature comparison" table (Figure 3) and ordering code breakdown (Figure 5, option 'E').
What is the ambient temperature rating for the FS32K148UAT0VLQT?
The FS32K148UAT0VLQT is rated for -40 °C to +105 °C ambient temperature (V-grade), validated for HSRUN mode operation. Its junction temperature limit is 125 °C under these conditions, meeting AEC-Q100 Grade 2 requirements for automotive body electronics applications.
