Application of Alioth Microcontroller Products
The Alioth series of microcontrollers are high-performance automotive control chips based on the Cortex M7 architecture, designed for functional safety level ASIL-D. They are widely used in core fields such as electric power steering, battery management systems, brake control systems, steer-by-wire, and electric drive controllers.
Core Advantages of the Solution
- Multi-core high-performance architecture: Supports up to 2 sets of lockstep cores with a maximum frequency of 300MHz, suitable for multi-task concurrency and complex control algorithms.
- ASIL-D functional safety design: Supports safety mechanisms such as hardware redundancy, ECC, lockstep mechanism, and dual-core comparison, meeting the ISO 26262 standard and applicable to critical task control.
- Rich on-chip resources: Integrates high-precision ADC (multi-channel, 12-bit), PWM, DSADC, suitable for motor control and analog sampling requirements, and incorporates a hardware FOC unit to reduce CPU load.
- Multi-channel communication interfaces: Provides abundant peripherals such as CAN-FD, Ethernet, LIN, and SPI, supporting seamless connection with the vehicle network.
- Powerful system security mechanisms: Built-in Hardware Security Module (HSM), supporting security protection functions such as secure boot, secure communication, and encrypted storage.
- Mature ecological support: Equipped with software resources such as AUTOSAR BSW, MCAL drivers, SafeTlib, and safety manuals, facilitating development, verification, and integration.
