Product details
Overview
FS32K148HFT0VLLT from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with 2 MB flash, 256 KB SRAM (ECC), and dual 12-bit ADCs. It operates at up to 112 MHz in HSRUN mode, supports CAN-FD, FlexCAN, Ethernet (10/100 Mbps with IEEE 1588), and cryptographic security via CSEc - deployed in vehicle body control modules requiring ASIL-B compliance and real-time deterministic response.
For engineers reviewing the FS32K148HFT0VLLT datasheet, FS32K148HFT0VLLT pinout, FS32K148HFT0VLLT application, or FS32K148HFT0VLLT equivalent, this page delivers verified package mapping (100-pin LQFP), validated power modes (HSRUN/RUN/STOP/VLPR/VLPS), confirmed peripheral counts (3x FlexCAN, 3x LPUART, 2x LPI2C, 3x LPSPI), and exact memory partitioning (64 KB FlexNVM for EEPROM emulation) - all traceable to NXP's Rev. 15 datasheet dated 5 March 2026.
Technical Context
The FS32K148HFT0VLLT integrates an Arm Cortex-M4F core with single-precision FPU and DSP extensions, executing at 112 MHz in HSRUN mode (2.97–5.5 V supply) or 80 MHz in RUN mode (2.7–5.5 V). Its crossbar switch (AXBS-Lite) enables concurrent access by CPU, DMA, and Ethernet to protected memory regions via NXP's system MPU - distinct from Arm Core MPU - enforcing ASIL-B–capable memory isolation across flash, SRAM, and FlexNVM.
It implements a multi-oscillator clock architecture: 4–40 MHz SOSC, 48 MHz FIRC, 8 MHz SIRC, and 128 kHz LPO, feeding an SPLL capable of 112 MHz system clock. Security operations (CSEc, EEPROM write/erase) are restricted to RUN mode (80 MHz); attempting them in HSRUN triggers error flags - a hard architectural constraint confirmed in datasheet Rev. 15 Section 1.1 and Figure 3 footnotes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K146HFT0VLLT | Same 100-pin LQFP package, identical pinout, but 1 MB flash and 192 KB SRAM - no Ethernet or SAI modules. | Lacks IEEE 1588 Ethernet and Serial Audio Interface - unsuitable for time-synchronized sensor hubs or audio gateway designs. | Select when Ethernet and SAI are unnecessary and cost optimization is prioritized over future-proofing. |
| S32K148HFT0MLLT | Identical feature set and pinout, but rated for -40°C to 125°C ambient (M-grade) instead of V-grade (-40°C to 105°C). | Validated for under-hood deployment where junction temperature reaches 135°C in RUN mode - required for engine bay ECUs. | Choose for high-temperature environments; otherwise, FS32K148HFT0VLLT suffices for cabin-mounted modules. |
Compared with S32K146HFT0VLLT, FS32K148HFT0VLLT adds Ethernet and SAI for time-critical networking and audio routing; versus S32K148HFT0MLLT, it trades thermal margin for lower cost in moderate-temperature zones - both alternatives retain full pin compatibility and software binary compatibility.

FAQ
What is the maximum operating frequency of the FS32K148HFT0VLLT and under what conditions?
The FS32K148HFT0VLLT achieves 112 MHz in HSRUN mode, guaranteed at 2.97–5.5 V supply and -40°C to +105°C ambient temperature. Below 2.97 V, operation requires RUN mode at 80 MHz. This distinction is critical: CSEc security operations and EEPROM writes are prohibited in HSRUN mode and must execute at 80 MHz - a hardware-enforced constraint documented in NXP's S32K1xx Data Sheet Rev. 15 Section 1.1.
Does the FS32K148HFT0VLLT support CAN-FD, and how many instances are available?
Yes, the FS32K148HFT0VLLT integrates three independent FlexCAN modules, each supporting CAN-FD per ISO 11898-1 with bit-rate switching up to 5 Mbps. All three are accessible in the 100-pin LQFP package (FS32K148HFT0VLLT), with dedicated TX/RX pins routed to separate physical layers - enabling simultaneous communication with powertrain, chassis, and infotainment networks without arbitration bottlenecks.
What memory resources does the FS32K148HFT0VLLT provide, and how is FlexNVM allocated?
The FS32K148HFT0VLLT includes 2 MB of program flash with ECC, 256 KB of SRAM with ECC, 64 KB of FlexNVM (also ECC-protected), and 4 KB of FlexRAM. FlexNVM is partitioned to support EEPROM emulation - up to 64 KB usable as data flash, with configurable backup sectors. This allocation is fixed in silicon and managed via the FTFC command set, not runtime reconfiguration.
Is the FS32K148HFT0VLLT pin-compatible with other S32K1xx devices in the same package?
Yes, all S32K1xx devices sharing the 100-pin LQFP package - including S32K142, S32K144, S32K146, and S32K148 variants - are fully pin-to-pin compatible per NXP's datasheet Figure 3 footnote. Signal multiplexing is consistent across the family; peripheral enablement depends solely on software configuration and clock gating - no PCB redesign is needed when upgrading within the same package footprint.
What debug interfaces does the FS32K148HFT0VLLT support, and are they available in all power modes?
The FS32K148HFT0VLLT supports Serial Wire Debug (SWD) via SWD_CLK and SWD_DIO pins, with full debug functionality (breakpoints, watchpoints, ITM trace, flash patching) active in RUN, HSRUN, and VLPR modes. Debug is disabled in STOP and VLPS modes to preserve power integrity - a deliberate design choice to prevent unintended wake-up or current leakage through debug circuitry during deep sleep.
