Vehicle‑grade MCU

Product Overview

Vehicle‑grade MCU is the core real‑time control processing unit of automotive electronic control systems, widely used in vehicle body control, powertrain management and auxiliary driving functional domains. Adhering strictly to AEC‑Q100 and ISO 26262 automotive functional safety specifications, the product features high operational reliability, anti‑interference capability and safety redundancy design. It undertakes sensor data acquisition, vehicle logic judgment, actuator drive control and bus data interaction, supporting long‑term stable operation of vehicle electronic systems under complex vehicle operating environments.

Core Electrical & Performance Characteristics

• Automotive grade certification: AEC‑Q100 Grade 1, supporting −40℃~150℃ ultra‑wide temperature working range

• Functional safety level: compliant with ASIL‑B/D safety grading requirements, supporting system fault diagnosis and fault tolerance

• Onboard bus resources: integrated multi‑channel CAN, CAN‑FD and LIN interfaces, supporting mainstream automotive bus protocols

• Built‑in protection mechanism: independent hardware watchdog, power‑on reset control and data encryption module

• Operating performance: high main frequency, abundant configurable GPIO and ADC sampling ports, supporting multi‑task real‑time scheduling

Adaptable Working Conditions

The device is specially optimized for vehicle harsh environments, resisting long‑term mechanical vibration, engine cabin high temperature heat accumulation, instantaneous vehicle voltage surge and drop, and strong electromagnetic interference generated by motors and high‑voltage components. It maintains stable program operation and accurate signal output under extreme temperature difference and dynamic road condition changes.

Product Advantages

Adopting automotive‑grade high‑reliability process design, the MCU features low failure rate and long service life matching vehicle full‑life cycle. Rich peripheral resources reduce external circuit design difficulty and BOM cost. Built‑in safety algorithm modules simplify vehicle factory functional safety development and shorten project mass production cycle.

Application Scenarios

Widely applicable to new energy vehicle motor electronic control units, battery management auxiliary control, vehicle body light control, door and window body control, as well as low‑speed auxiliary driving and sensing signal processing systems for passenger cars and commercial vehicles.

Selection & Usage Notes

Different core configurations and safety grade models should be selected according to vehicle functional safety requirements and application domains. Power supply circuit design must follow automotive EMC specifications. During mass production welding and assembly, strictly control temperature and time to avoid damage to internal wafer structure. Reserve sufficient electromagnetic isolation space in PCB layout to ensure long‑term stable vehicle operation.
