Product details
Overview
FS32K146HAT0MLLT from NXP Semiconductors is an automotive-grade Arm Cortex-M4F microcontroller with 2 MB flash, 256 KB SRAM (both with ECC), and dual 12-bit ADCs supporting up to 32 channels each. It operates at 112 MHz in HSRUN mode or 80 MHz in RUN mode across -40 °C to +125 °C ambient, targeting body control modules and gateway ECUs requiring ASIL-B compliance and cryptographic security.
For engineers reviewing the FS32K146HAT0MLLT datasheet, FS32K146HAT0MLLT pinout, FS32K146HAT0MLLT application, or FS32K146HAT0MLLT equivalent, key selection criteria include its 156 GPIO count, FlexCAN with optional CAN-FD support, CSEc-based hardware security, and compatibility with NXP S32 Design Studio for functional safety development.
Technical Context
The FS32K146HAT0MLLT integrates an Arm Cortex-M4F core with single-precision FPU and DSP extensions, executing at up to 112 MHz in HSRUN mode while maintaining full peripheral availability except for CSEc and EEPROM operations - which require switching to 80 MHz RUN mode. Its AXBS-Lite crossbar switch enables concurrent access by CPU, DMA, and Ethernet MAC to memory and peripherals.
Power management includes five low-power modes (HSRUN, RUN, STOP, VLPR, VLPS) with PMC-controlled clock gating, and safety features include System MPU (crossbar-level memory protection), ECC on flash/SRAM, CRC module, WDOG, EWM, and IEEE 1588-capable 10/100 Mbps Ethernet MAC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M4F with FPU and DSP extensions - enables real-time signal processing and floating-point math in motor control and sensor fusion. |
| Max Clock Frequency | 112 MHz (HSRUN mode); 80 MHz (RUN mode) - higher frequency supports time-critical tasks but requires mode switch for secure operations. |
| Flash / SRAM | 2 MB program flash + 64 KB FlexNVM (ECC protected); 256 KB SRAM + 4 KB FlexRAM - sufficient for AUTOSAR OS, diagnostics, and OTA update storage. |
| ADC | Two 12-bit SAR ADCs, up to 32 inputs each, 1 Msps - supports simultaneous sampling of multiple vehicle sensors (e.g., temperature, pressure, position). |
| Communication | 3× FlexCAN (CAN-FD capable), 3× LPUART/LIN, 3× LPSPI, 2× LPI2C, FlexIO, QuadSPI/HyperBus - enables multi-bus vehicle networking and legacy protocol bridging. |
| Security | Cryptographic Services Engine (CSEc) compliant with SHE spec - provides AES-128, SHA-256, RNG, and secure boot without external crypto IC. |
| Temperature Grade | -40 °C to +125 °C ambient (M-grade) - qualified for under-hood applications including engine control and battery management. |
| Package | 100-pin LQFP (MLLT suffix) - pin-compatible with other S32K14x devices in same package, enabling scalable platform design. |
Pinout & Package
FS32K146HAT0MLLT is housed in a 100-pin LQFP (7 mm × 7 mm, 0.5 mm pitch) package with exposed thermal pad. Pin functions are defined per the S32K1xx Reference Manual IO Signal Description sheet, supporting multiplexed I/O for flexible peripheral assignment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Power supply and analog reference | Must be decoupled individually; VDD/VDDA differential ≤ ±0.1 V ensures ADC accuracy and stable core operation. |
| RESET_B | Active-low reset input | Accepts external reset assertion; internal POR/BOR ensures reliable startup across voltage ramp rates (0.5 V/min to 100 V/ms). |
| SWD_CLK, SWD_IO | Serial Wire Debug interface | Enables non-intrusive debug, trace, and flash programming via SWJ-DP; supports ITM, DWT, and TPIU for real-time analysis. |
| CAN0_TX, CAN0_RX | FlexCAN channel 0 differential pair | Supports ISO 11898-1 CAN and CAN-FD (up to 5 Mbps); requires external transceiver and termination for bus compliance. |
| ADC0_SE0–ADC0_SE31 | Analog input channels (Bank 0) | Configurable as single-ended or differential; supports hardware-triggered conversions synchronized with FTM or PDB for precise timing. |
| GPIO_00–GPIO_155 | General-purpose I/O | 156 pins with interrupt capability, configurable pull-up/down, slew rate control, and glitch filtering - suitable for switch sensing, LED driving, and LIN physical layer. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Ready Architecture | System MPU enforces memory access rights per master (CPU/DMA/Ethernet); ECC on flash/SRAM detects/corrects single-bit errors in safety-critical code/data. |
| Multi-Mode Power Management | PMC supports five power modes with sub-microsecond wake-up from VLPS; clock gating reduces dynamic power in unused peripherals during RUN/HSRUN. |
| Flexible Timing Subsystem | Eight FTM modules (64 PWM/IC/OC channels), LPIT (4-channel), LPTMR, PDB, and RTC enable complex motor commutation, PWM generation, and time-stamped event capture. |
| Secure Boot & Cryptography | CSEc implements AES-128-ECB/CBC/CTR, SHA-256, HMAC-SHA256, and TRNG - enables authenticated firmware updates and secure key storage without software overhead. |
| Automotive Communication Suite | Three FlexCAN controllers (CAN-FD optional), three LPUARTs (LIN v2.2A compliant), two LPI2Cs, and FlexIO for UART/I2C/SPI emulation - simplifies integration into mixed-protocol vehicle networks. |
| High-Resolution Analog Front-End | Dual 12-bit ADCs with 1 Msps, 32-channel input mux, and hardware trigger support - meets requirements for high-fidelity sensor acquisition in ADAS and chassis control. |

FAQ
What is the maximum operating frequency of the FS32K146HAT0MLLT and under what conditions?
The FS32K146HAT0MLLT operates at up to 112 MHz in HSRUN mode and 80 MHz in RUN mode. HSRUN mode supports full peripheral functionality except CSEc execution and EEPROM writes/erases, which require switching to RUN mode. The device is rated for -40 °C to +125 °C ambient in RUN mode, with junction temperature limited to 135 °C.
Does the FS32K146HAT0MLLT support CAN-FD, and how many CAN interfaces does it include?
Yes, the FS32K146HAT0MLLT includes three FlexCAN modules, each capable of CAN-FD operation per ISO 11898-1. CAN-FD support must be enabled in software configuration; physical layer compliance requires an external CAN-FD transceiver. All three CAN controllers are accessible in the 100-pin LQFP package.
What memory protection mechanisms are implemented in the FS32K146HAT0MLLT?
The FS32K146HAT0MLLT implements a System Memory Protection Unit (MPU) at the crossbar switch level, enforcing access rights per master (CPU, DMA, Ethernet). It also includes ECC on 2 MB flash and 256 KB SRAM to detect and correct single-bit errors, plus a CRC module for data integrity verification in memory transfers and peripheral buffers.
How does the FS32K146HAT0MLLT handle secure boot and cryptographic operations?
The FS32K146HAT0MLLT uses the Cryptographic Services Engine (CSEc) to perform AES-128, SHA-256, HMAC-SHA256, and TRNG operations in hardware. Secure boot validates signed firmware images before execution. CSEc keys are stored in protected memory; all security operations require RUN mode (80 MHz), not HSRUN mode.
Is the FS32K146HAT0MLLT pin-compatible with other S32K14x devices in the same package?
Yes, all S32K14x devices sharing the 100-pin LQFP package (e.g., FS32K144HAT0MLLT, FS32K148HAT0MLLT) are pin-to-pin compatible per the S32K1xx Data Sheet. Peripheral availability depends on pin multiplexing configuration, and the IO Signal Description document defines function mapping for each pin in this package variant.
