Product details
Overview
FS32K146HFT0VLHT from NXP Semiconductors is an automotive-grade Arm® Cortex-M4F microcontroller designed for safety-critical body electronics and powertrain control. It operates at up to 112 MHz in HSRUN mode, features 2 MB program flash with ECC, 256 KB SRAM with ECC, and supports -40 °C to 105 °C ambient operation. Its integrated CSEc security engine, FlexCAN with optional CAN-FD, and dual 12-bit ADCs enable robust real-time control in ECU applications.
For engineers reviewing the FS32K146HFT0VLHT datasheet, FS32K146HFT0VLHT pinout, FS32K146HFT0VLHT application, or FS32K146HFT0VLHT equivalent, this page delivers verified technical context, package-specific pin mapping, functional alternatives, and supply-chain-ready availability details - all grounded in NXP's S32K1xx Rev. 15 datasheet and orderable part documentation.
Technical Context
The FS32K146HFT0VLHT implements a dual-core architecture with Arm Cortex-M4F as primary execution core (112 MHz HSRUN / 80 MHz RUN) and Cortex-M0+ for low-power background tasks. It integrates NXP's system-level Memory Protection Unit (MPU) at the AXBS-Lite crossbar switch, enforcing ASIL-B–capable memory access control across CPU, DMA, and Ethernet masters - distinct from Arm Core MPU.
Its clock system includes SOSC (4–40 MHz), FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SPLL (up to 112 MHz), with automatic failover and configurable gating. Power management supports five modes (HSRUN, RUN, STOP, VLPR, VLPS), though CSEc operations and EEPROM emulation require explicit transition from HSRUN to RUN mode (80 MHz) due to hardware-enforced exclusion.

FAQ
What is the maximum operating frequency of the FS32K146HFT0VLHT?
The FS32K146HFT0VLHT operates at up to 112 MHz in HSRUN mode and 80 MHz in RUN mode. The 112 MHz frequency is validated for general-purpose computation and peripheral control, but CSEc security operations and EEPROM emulation must be executed in RUN mode (80 MHz) per hardware restriction documented in the S32K1xx datasheet Rev. 15.
Does the FS32K146HFT0VLHT support CAN-FD?
Yes, the FS32K146HFT0VLHT supports CAN-FD through its three FlexCAN modules. The 'F' in the orderable part number FS32K146HFT0VLHT explicitly denotes CAN-FD capability, as confirmed in the S32K1xx_Orderable_Part_Number_List.xlsx and Feature Comparison tables.
What package type is used for the FS32K146HFT0VLHT?
The FS32K146HFT0VLHT uses a 100-pin LQFP package (code LH), with 0.5 mm pitch and 14 × 14 mm body size. This package is pin-to-pin compatible with other S32K14x devices offered in the same 100-pin LQFP variant, enabling design reuse across performance tiers.
How does the CSEc security engine function in the FS32K146HFT0VLHT?
The FS32K146HFT0VLHT integrates NXP's Cryptographic Services Engine (CSEc), compliant with the SHE specification. It performs AES-128, SHA-256, RNG, and secure key storage. However, CSEc operations - including secure boot key provisioning - require the device to be in RUN mode (80 MHz), not HSRUN mode (112 MHz), as enforced by hardware error flag generation.
What is the temperature grade of the FS32K146HFT0VLHT?
The FS32K146HFT0VLHT is rated for V-grade operation: -40 °C to +105 °C ambient temperature. This grade is validated for under-hood and cabin-mounted automotive ECUs and aligns with ISO/TS 16949 requirements for production automotive components.
