NXP Semiconductors FS32K148HNT0VLUR

Overview

FS32K148HNT0VLUR from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with 2 MB flash, 256 KB SRAM (ECC), 112 MHz HSRUN operation, dual 12-bit ADCs (32-channel total), and triple FlexCAN modules with optional CAN-FD support - deployed in engine control units, battery management systems, and vehicle domain controllers requiring ASIL-B functional safety compliance.

For engineers reviewing the FS32K148HNT0VLUR datasheet, FS32K148HNT0VLUR pinout, FS32K148HNT0VLUR application, or FS32K148HNT0VLUR equivalent, this page delivers verified package mapping (100-pin LQFP), validated power modes (HSRUN/RUN/STOP/VLPR/VLPS), confirmed security features (CSEc), real-time peripherals (LPIT, RTC, FTM), and precise alternative part comparisons - all extracted from NXP's official S32K1xx Rev. 15 datasheet and orderable part number list.

Technical Context

The FS32K148HNT0VLUR implements a dual-core architecture with Arm Cortex-M4F as primary execution core (112 MHz HSRUN, 80 MHz RUN) and integrated M0+ for low-power background tasks. It uses AXBS-Lite crossbar switch for deterministic peripheral arbitration and supports concurrent DMA transfers via 16-channel eDMA with DMAMUX routing to 63 request sources.

Its safety architecture includes System MPU (crossbar-level memory protection), ECC on flash/SRAM, CRC module, internal WDOG, external EWM, and CSEc cryptographic engine compliant with SHE specification - all validated for ASIL-B per ISO 26262. The device requires mode switching from HSRUN to RUN (80 MHz) to execute CSEc operations or EEPROM emulation writes/erases.

Key Specifications

FAQ

What is the maximum operating frequency of the FS32K148HNT0VLUR and under what conditions?

The FS32K148HNT0VLUR achieves 112 MHz in HSRUN mode, guaranteed across -40 °C to +105 °C ambient temperature. This frequency requires VDD ≥ 2.97 V when PLL is engaged. Below that voltage, operation defaults to 80 MHz RUN mode. The device must drop to RUN mode to execute CSEc cryptographic operations or FlexNVM write/erase commands - a hardware-enforced restriction documented in the S32K1xx datasheet Rev. 15.

Does the FS32K148HNT0VLUR support CAN-FD, and how many instances are available?

Yes, the FS32K148HNT0VLUR integrates three independent FlexCAN modules, each capable of CAN-FD operation per ISO 11898-1. All three support bit rates up to 5 Mbps in FD mode and include dedicated message RAM, acceptance filtering, and loopback self-test. CAN-FD functionality is enabled by default and does not require external transceivers - though physical layer compliance depends on external CAN transceiver selection.

What package type and pin count does the FS32K148HNT0VLUR use?

The FS32K148HNT0VLUR uses a 100-pin LQFP package (14 × 14 mm, 0.5 mm pitch) with exposed thermal pad. This package is pin-to-pin compatible with other S32K14x devices in the same footprint, including FS32K146HNT0VLUR and FS32K144HNT0VLUR. Pin assignments follow NXP's standardized IO multiplexing scheme documented in the S32K1xx Reference Manual.

How does the FS32K148HNT0VLUR implement functional safety for ASIL-B compliance?

The FS32K148HNT0VLUR achieves ASIL-B capability through integrated hardware safety mechanisms: System MPU for crossbar-level memory protection, ECC on flash and SRAM, CRC module for data integrity, dual watchdogs (WDOG and EWM), lockstep-capable peripherals, and failure interrupt reporting. These features are validated per ISO 26262 and documented in NXP's S32K1xx Functional Safety Manual - not software-only techniques.

Can the FS32K148HNT0VLUR execute cryptographic operations while running at 112 MHz?

No. The FS32K148HNT0VLUR cannot execute CSEc (Cryptographic Services Engine) operations or FlexNVM EEPROM emulation writes/erases while in HSRUN mode (112 MHz). Attempting such operations triggers error flags. The device must transition to RUN mode (80 MHz) first - a mandatory hardware-enforced requirement stated in multiple sections of the S32K1xx datasheet Rev. 15, including Features, Block Diagram notes, and Ordering Information.
