Product details
Overview
FS32K148UJT0VLQR from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with 2 MB flash, 256 KB SRAM, and integrated CSEc security engine. It operates at up to 112 MHz in HSRUN mode (−40 °C to +105 °C), supports CAN-FD, Ethernet, FlexIO, and IEEE-1588 timing - deployed in vehicle body control modules requiring ASIL-B functional safety compliance.
For engineers reviewing the FS32K148UJT0VLQR datasheet, FS32K148UJT0VLQR pinout, FS32K148UJT0VLQR application, or FS32K148UJT0VLQR equivalent, this page delivers verified package mapping (100-pin LQFP), confirmed HSRUN/RUN mode behavior, validated CSEc security constraints, and real-world automotive timing and communication interface specifications - all traceable to NXP's Rev. 15 S32K1xx Data Sheet (5 March 2026).
Technical Context
The FS32K148UJT0VLQR implements a dual-core capable architecture with Arm Cortex-M4F core (112 MHz HSRUN / 80 MHz RUN) and optional M0+ co-processor support per family design, featuring integrated FPU, DSP extensions, and configurable NVIC. Its memory subsystem includes ECC-protected 2 MB flash, 256 KB SRAM, 64 KB FlexNVM for EEPROM emulation, and 4 KB FlexRAM.
Peripheral integration includes three FlexCAN modules (all with CAN-FD), one 10/100 Mbps Ethernet MAC with IEEE-1588 timestamping, two SAI interfaces, QuadSPI with HyperBus™ support, eight FlexTimer modules (64 PWM/IC/OC channels), and hardware-accelerated cryptographic services via CSEc - all coordinated through AXBS-Lite crossbar switch and eDMA with DMAMUX routing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K146UJT0VLQR | 1 MB flash, 192 KB SRAM, no Ethernet or SAI; same 100-pin LQFP and CSEc | Lacks IEEE-1588 Ethernet and audio interfaces - suitable for CAN/LIN-only gateways or BCMs without OTA bandwidth needs | Select when system does not require Ethernet connectivity or audio processing, reducing cost and BOM complexity |
| S32K148UJT0MLQR | Same features but M-grade (−40 °C to +125 °C); requires RUN mode (80 MHz) for CSEc operations | Rated for higher ambient temperature - used in under-hood powertrain or ADAS domain controllers where thermal margin exceeds V-grade limits | Choose for engine bay placement or high-temperature zones where junction temperature may exceed 125 °C |
Compared with FS32K148UJT0VLQR, S32K146UJT0VLQR reduces memory and removes Ethernet while retaining pin compatibility and security; S32K148UJT0MLQR maintains identical functionality but extends thermal rating to +125 °C ambient - both serve distinct automotive deployment tiers without layout changes.

FAQ
What is the maximum operating frequency of the FS32K148UJT0VLQR and under what conditions?
The FS32K148UJT0VLQR achieves up to 112 MHz in HSRUN mode, but only when supplied with ≥2.97 V and operating within −40 °C to +105 °C ambient. At lower voltages or outside this temperature range, it defaults to 80 MHz RUN mode. This constraint is explicitly documented in NXP's S32K1xx Data Sheet Rev. 15, Section 5.2, Table 3.
Does the FS32K148UJT0VLQR support CAN-FD, and how many instances are available?
Yes, the FS32K148UJT0VLQR integrates three independent FlexCAN modules, all supporting CAN-FD per ISO 11898-1. Each module supports bit rates up to 5 Mbps and includes dedicated message RAM, acceptance filtering, and loopback/self-test modes - confirmed in the S32K1xx Data Sheet Rev. 15, Section 3.1 Feature Comparison table.
Can the FS32K148UJT0VLQR execute CSEc security operations at 112 MHz?
No. The FS32K148UJT0VLQR triggers error flags if CSEc (Cryptographic Services Engine) operations or EEPROM writes/erases are attempted in HSRUN mode (112 MHz). It must switch to RUN mode (80 MHz) to perform these functions - a hard requirement stated in multiple locations in the S32K1xx Data Sheet Rev. 15, including Sections 1.1, 2, and 4.2.
What package type and pin count does the FS32K148UJT0VLQR use?
The FS32K148UJT0VLQR uses a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. This matches the "LQ" code in its orderable part number and is confirmed in Figure 3 (S32K1xx product series comparison) and Section 4.2 of the S32K1xx Data Sheet Rev. 15.
Is QuadSPI with HyperBus™ supported on the FS32K148UJT0VLQR?
QuadSPI with HyperBus™ is supported on the FS32K148UJT0VLQR, but only in packages that include the required QSPI pins - notably excluded from the 100-pin LQFP variant per footnote 6 in Figure 3 of the S32K1xx Data Sheet Rev. 15. Therefore, FS32K148UJT0VLQR (100-pin LQFP) does not support QuadSPI/HyperBus™.
