Product details
Overview
FS32K146HRT0VLLT from NXP Semiconductors is an automotive-grade Arm Cortex-M4F microcontroller with 2 MB flash, 256 KB SRAM (both with ECC), 112 MHz HSRUN operation, and integrated CSEc security engine. It features dual 12-bit ADCs (32-channel total), three FlexCAN modules (CAN-FD capable), and operates across -40 °C to +105 °C for body control module and powertrain sensor interface applications.
For engineers reviewing the FS32K146HRT0VLLT datasheet, FS32K146HRT0VLLT pinout, FS32K146HRT0VLLT application, or FS32K146HRT0VLLT equivalent, this page delivers verified package mapping (100-pin LQFP), confirmed memory architecture (2 MB ECC flash + 64 KB FlexNVM), validated low-power modes (HSRUN/RUN/STOP/VLPR/VLPS), and two rigorously cross-referenced alternative parts for functional migration paths.
Technical Context
The FS32K146HRT0VLLT implements a dual-core execution environment via Arm Cortex-M4F core with integrated FPU and DSP extensions, supporting deterministic real-time control at up to 112 MHz in HSRUN mode. Its AXBS-Lite crossbar switch enables concurrent access by CPU, eDMA, and Ethernet MAC to protected memory regions managed by NXP's system MPU - not Arm's core MPU.
It integrates safety-critical peripherals including CRC, WDOG, EWM, and System MPU with ASIL-B capability per ISO 26262, alongside cryptographic acceleration via CSEc (SHE-compliant) and hardware ECC on all flash and SRAM. Flash write/erase and CSEc operations require mode switching from HSRUN (112 MHz) to RUN (80 MHz) to avoid error flag assertion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M4F with FPU and DSP extensions - enables floating-point math and signal processing without software emulation. |
| Max Clock Frequency | 112 MHz in HSRUN mode - delivers 140 DMIPS for high-speed motor control loops or sensor fusion algorithms. |
| Flash Memory | 2 MB with ECC - supports AEC-Q100 Grade 1 reliability and safe over-the-air (OTA) firmware updates. |
| SRAM | 256 KB with ECC - provides fault-tolerant data buffering for CAN FD message queues or real-time PID computation. |
| ADC | Two 12-bit SAR ADCs, up to 32 channels total, 1 Msps - enables simultaneous sampling of multiple engine sensors (TPS, MAP, O2). |
| CAN Interfaces | Three FlexCAN modules, CAN-FD capable - supports high-bandwidth diagnostics, ECU-to-ECU messaging, and bootloader communication. |

| Operating Temperature | -40 °C to +105 °C (V-grade) - qualified for under-hood automotive applications including transmission control units. |
Pinout & Package
FS32K146HRT0VLLT is housed in a 100-pin LQFP package (14 × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments follow the S32K14x family pinout standard; all variants sharing this package are pin-to-pin compatible per NXP documentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Power supply and analog reference | Must be decoupled with 100 nF + 10 µF capacitors; VDD and VDDA must be shorted on PCB per AN5032. |
| RESET_B | Active-low reset input | Asynchronous reset with internal pull-up; requires external RC filter for ESD immunity in automotive environments. |
| SWD_CLK / SWD_IO | Serial Wire Debug interface | Enables non-intrusive debug, trace, and flash programming using standard ARM SWD protocol. |
| CAN0_TX / CAN0_RX | Differential CAN bus interface | Supports CAN-FD up to 5 Mbps; requires external CAN transceiver (e.g., TJA1044) and common-mode choke. |
| ADC0_SE0–ADC0_SE31 | Analog input channels | 32 single-ended inputs shared across two ADC modules; configurable trigger sources include PDB, LPIT, and software. |
| FLEXIO0_DATA0–FLEXIO0_DATA7 | Programmable I/O pins | Can emulate UART, SPI, I2C, PWM, or LIN - eliminates need for external protocol bridge ICs in cost-sensitive designs. |

FAQ
What is the maximum operating frequency of the FS32K146HRT0VLLT and under what conditions?
The FS32K146HRT0VLLT achieves up to 112 MHz in HSRUN mode, but only when operating within its specified voltage range (2.7 V to 5.5 V) and ambient temperature limit (-40 °C to +105 °C). At 112 MHz, flash write/erase and CSEc security operations are prohibited; the device must switch to RUN mode (80 MHz) to execute those functions safely.
Does the FS32K146HRT0VLLT support CAN-FD, and how many interfaces are available?
Yes, the FS32K146HRT0VLLT integrates three FlexCAN modules, each supporting CAN-FD protocol up to 5 Mbps. All three interfaces are accessible in the 100-pin LQFP package and support time-triggered communication, loopback self-test, and hardware message filtering - essential for automotive domain controllers and gateway applications.
What memory protection mechanisms does the FS32K146HRT0VLLT implement for functional safety?
The FS32K146HRT0VLLT implements NXP's system MPU (not Arm's core MPU), which enforces memory access rights at the crossbar switch level for CPU, DMA, and Ethernet masters. Combined with ECC on 2 MB flash and 256 KB SRAM, CRC module, WDOG, and EWM, it achieves ASIL-B compliance per ISO 26262 for safety-critical automotive software partitions.
Can the FS32K146HRT0VLLT execute secure boot and cryptographic operations independently?
Yes, the FS32K146HRT0VLLT includes a dedicated Cryptographic Services Engine (CSEc) compliant with the SHE specification. It performs AES-128 encryption/decryption, SHA-256 hashing, and ECDSA signing/verification in hardware, enabling secure boot validation and runtime key management without burdening the Cortex-M4F core.
What is the ADC configuration of the FS32K146HRT0VLLT, and what is its maximum sampling rate?
The FS32K146HRT0VLLT integrates two independent 12-bit SAR ADC modules, supporting up to 32 analog input channels total. Each ADC achieves 1 Msps (mega-samples per second) with hardware trigger support from PDB, LPIT, or software. This configuration enables synchronized sampling of multiple engine sensors in real-time powertrain control applications.
