Yuntu Dual-Core MCU Core Solution for Main Drive Motor ECU

In the main drive motor control unit of modern new energy vehicles, the system must simultaneously process high-dynamic motor control algorithms, multi-sensor fusion, and vehicle communication protocols. The mainstream architecture has evolved from single-core to a "high-frequency dual-core + rich peripheral" design. Dual-core MCUs, leveraging their physically isolated computing resources, enable perfect hard real-time decoupling of control tasks from communication/safety monitoring tasks. This fundamentally resolves the control loop latency and uncertainty caused by task scheduling in single-core solutions, providing a solid hardware foundation to meet the highest ASIL-D functional safety level. It is the core enabler for high-reliability, high-response-speed electric drive systems.

Within the main drive motor ECU, a 300MHz+300MHz symmetric dual-core architecture ideally distributes critical system tasks. One core can be dedicated to executing high-frequency FOC/SVPWM algorithms, position decoding, and current loop control, ensuring a current loop period of ≤10μs and nanosecond-level PWM accuracy. The other core handles real-time ISO 26262-compliant fault diagnosis, multi-channel CAN-FD communication, torque safety monitoring, and thermal management strategies. Its core advantage lies in eliminating resource-sharing conflicts through hardware-level concurrency. Even during complex online identification or OTA updates, the computing power and timeliness of the motor control core remain completely unaffected, thereby guaranteeing absolutely smooth and safe vehicle power response.

Yuntu's YTM32B1HA01GOMLLT is a dual-core MCU tailor-made for such high-performance applications. This product integrates two 300MHz ARM Cortex-M7 cores, is equipped with up to 2.25MB of on-chip SRAM and 256KB cache, and comes in an LQFP100 package capable of operating in the harsh automotive temperature range of -40°C to 150°C. Its application advantages in main drive motor ECUs are highlighted by the following core parameters:

1.  Symmetric High-Performance Dual Cores: Both Cortex-M7 cores can operate independently at 300MHz and have access to all control peripherals, providing unparalleled computational redundancy and flexible software architecture deployment, far exceeding common "big.LITTLE" architectures.

2.  Large-Capacity Tightly Coupled Memory: With up to 2.25MB of zero-wait-state SRAM, it can concurrently hold multiple sets of control algorithms, fault data logs, and communication stacks, eliminating the need for external memory expansion and significantly boosting data access speed and system reliability.

3.  High-Precision & High-Speed Peripherals: Integrates multiple motor control timers supporting high-resolution PWM and fast ADC, capable of directly driving multi-phase motors. Their nanosecond-level latency ensures precise torque control.

4.  Top-Tier Functional Safety Support: The chip is designed to meet ASIL-D level requirements, featuring a built-in Hardware Security Module (HSM), dual-core lock-step detection, and extensive Memory Protection Units (MPUs), clearing hardware obstacles for developing electronic control systems compliant with the highest ISO 26262 safety standards.

The chip's heterogeneous communication interfaces (such as multiple CAN-FD and Ethernet) facilitate the construction of complex vehicle network nodes.
