Features
ARM Cortex-M33 Core
XMotiv™ M3 delivers real-time, predictable, and deterministic computing capabilities, supporting the stringent requirements of automotive control systems for smooth driving, rapid response, and high reliability. Based on the ARM M33 architecture, it features a built-in DSP and FPU, and operates at a maximum frequency of 160 MHz, making it suitable for real-time control tasks such as motor control loops, sensor fusion, and in-vehicle communication.
Extensive Peripheral Interface
XMotiv™ M3 is designed specifically for automotive body control. Its flexible and scalable interface eases the integration of distributed ECUs and smart actuators while ensuring highly predictable communication behavior. The system integrates 3 × CAN-FD, 8 × LIN, 6 × UART, 6 × SPI, and 6 × I²C interfaces, with full DMA support, enabling it to effectively meet the demands of high-bandwidth data transmission and multi-subsystem integration.
Automotive-Grade Safety & Security
XMotiv™ M3 protects critical vehicle functions through built-in security mechanisms and hardware-level protection, supporting ISO 26262 functional safety requirements and reducing system risks. Its ASIL-B Ready architecture integrates hardware-based AES-256 and SHA-512 encryption, ECC memory protection, and secure boot—all compliant with the ISO 21434 standard—to ensure system integrity and trusted execution.
Precision Sensing & Real-Time Control
XMotiv™ M3 provides precise sensing, signal conditioning, and drive capabilities for powertrain, body, and comfort systems, meeting real-time control requirements through rigorous timing control and accurate feedback. Featuring a built-in 12-bit ADC (32 channels), a 16-channel DMA, multiple comparators, and up to 16 PWM timers, it's suitable for a wide range of automotive and robotics control applications.
Adaptive Power & System Management
XMotiv™ M3 optimizes power consumption in active and low-power modes, reduces thermal load, and improves the overall operational efficiency of the subsystem. The system integrates an adaptive clock gate and a multi-mode PMU (normal/standby/sleep), combined with a low-power 128 kHz oscillator, to maintain stable performance even within the automotive-grade temperature range.

Applications
Adaptive Driving Beam
Adaptive Driving Beam (ADB) headlights rely on precise timing and real-time LED adjustments to improve visibility and reduce glare. The 160 MHz ARM Cortex-M33 core, equipped with DCLS, supports microsecond-level segmentation and rapid beam shaping, while CAN-FD and SPI ensure reliable communication with the lighting ECU. Hardware encryption protects control messages, and ASIL-B functional safety maintains predictable behavior in the event of a failure.
Safety Orchestration
Safety-critical modules rely on consistent diagnostic mechanisms, secure communication, and high-integrity monitoring within distributed vehicle systems to ensure predictable and reliable system behavior. The ARM Cortex-M33 core, equipped with DCLS, accelerates safety processes and fault detection, while the AES/SHA hardware cryptographic engines protect critical data paths. Independent watchdog and ECC memory protection mechanisms further enhance system integrity and provide the necessary diagnostic coverage through an ASIL-B design path.
Dynamic Stabilization
Motor drive systems—ranging from pumps and fans to various actuators and robotic applications—rely on precise PWM control and stable torque output under different load conditions. The ARM Cortex-M33 core supports high-speed control loops and dynamic adjustments. Combined with a 12-bit ADC, high-resolution timers, and multiple PWM channels, it delivers precise and predictable control performance. CAN-FD, LIN, and SPI communication interfaces ensure reliable coordination with motor drivers, supported by ASIL-B functional safety mechanisms.
