Product details
Overview
FS32K148UAT0VLLT from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller designed for safety-critical body control, gateway, and domain controller applications. It operates at up to 112 MHz in HSRUN mode, integrates 2 MB ECC-protected flash, 256 KB SRAM with ECC, and supports CAN-FD, Ethernet (10/100 Mbps), and IEEE 1588 time synchronization.
For engineers reviewing the FS32K148UAT0VLLT datasheet, FS32K148UAT0VLLT pinout, FS32K148UAT0VLLT application, or FS32K148UAT0VLLT equivalent, this page delivers 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 FS32K148UAT0VLLT implements a dual-core capable architecture with Arm Cortex-M4F core (112 MHz HSRUN / 80 MHz RUN) and optional M0+ co-processor support via software configuration. It features a system-level Memory Protection Unit (MPU) enforcing access rights per master (CPU, DMA, Ethernet) at the AXBS-Lite crossbar switch - distinct from Arm Core MPU - enabling ASIL-B compliance.
Its power management includes five modes (HSRUN, RUN, STOP, VLPR, VLPS), with CSEc security operations and EEPROM emulation restricted to RUN mode (80 MHz) due to hardware arbitration constraints. Clocking combines SOSC (4–40 MHz), FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SPLL (up to 112 MHz), supporting precise timing for CAN-FD, Ethernet, and RTC functions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K146UAT0VLLT | Same 100-pin LQFP package, identical pinout; reduced flash (1 MB) and SRAM (192 KB); no Ethernet or SAI modules. | Suitable for mid-tier gateways without Ethernet backbone or audio processing; lower BOM cost where bandwidth < 100 Mbps suffices. | Select when Ethernet and dual CAN-FD are not required; retains same PCB layout and toolchain compatibility. |
| MC9S12XEQ512MLM | Legacy 16-bit S12XE architecture; no Arm Cortex-M4F, no CAN-FD, no Ethernet, no CSEc; 512 KB flash, -40°C to +125°C. | Used in legacy ECU redesigns requiring drop-in replacement with minimal software porting; lacks ASIL-B MPU and modern security. | Choose only for brownfield upgrades with strict legacy code reuse; not recommended for new designs targeting ASIL-B or CAN-FD. |
Compared with FS32K148UAT0VLLT, S32K146UAT0VLLT offers identical mechanical and electrical compatibility but trades Ethernet and extended memory for cost reduction, while MC9S12XEQ512MLM represents a legacy platform lacking safety-certifiable peripherals and modern protocol support.

FAQ
What is the maximum operating frequency of the FS32K148UAT0VLLT and under what conditions?
The FS32K148UAT0VLLT achieves up to 112 MHz in HSRUN mode, but only when supplied within 2.97–5.5 V and operating at ambient temperatures ≤105 °C. Below 2.97 V, the device defaults to 80 MHz RUN mode. This frequency is validated with SPLL enabled and requires proper decoupling and thermal management per AN5426.
Does the FS32K148UAT0VLLT support CAN-FD, and how many instances are available?
Yes, the FS32K148UAT0VLLT integrates three independent FlexCAN modules, all supporting CAN-FD (ISO 11898-1 FD) with data rates up to 8 Mbit/s. Each module has dedicated TX/RX pins and supports protocol arbitration, bit-rate switching, and flexible data-length payloads - confirmed in the S32K1xx Data Sheet Rev. 15 feature comparison table.
What package type and pin count does the FS32K148UAT0VLLT use?
The FS32K148UAT0VLLT uses a 100-pin LQFP package (code LL), measuring 14 mm × 14 mm with 0.5 mm pitch. This matches the pinout defined for S32K14x 100-pin LQFP variants and supports full peripheral availability including Ethernet RMII, three CAN-FD channels, and dual 12-bit ADCs.
Can the FS32K148UAT0VLLT execute CSEc security operations in HSRUN mode?
No. The FS32K148UAT0VLLT cannot execute CSEc cryptographic operations or FlexNVM EEPROM emulation while in HSRUN mode (112 MHz). As documented in the S32K1xx Data Sheet Rev. 15, these functions trigger error flags and require explicit transition to RUN mode (80 MHz) - a hardware-enforced restriction for timing and arbitration safety.
Is Ethernet functionality supported on the FS32K148UAT0VLLT, and what standards does it implement?
Yes, the FS32K148UAT0VLLT includes a full 10/100 Mbps IEEE 802.3 Ethernet MAC with integrated IEEE 1588-2008 Precision Time Protocol (PTP) support. It implements RMII interface, hardware timestamping, and VLAN tagging - enabling time-synchronized communication for automotive gateways and ADAS domain controllers.
