## Functions

1. Automotive main‑controller MCU for body / gateway application software, handles multi‑bus data routing, I/O control and ADC signal acquisition.

2. Hardware‑implemented ASIL‑B functional safety with memory ECC error correction to detect memory faults and ensure reliability of automotive ECUs.

3. Integrated HSM hardware security module enables encrypted communication and secure boot, preventing firmware tampering and bus hijacking.

4. Supports deep‑sleep modes for low‑power standby after vehicle ECU power‑off and fast wake‑up.

5. Multi‑channel eDMA offloads CPU load, processing massive CAN‑FD, Ethernet and LIN bus data simultaneously, ideal for high‑volume message routing in gateways.

## Application Fields

### Primary Automotive Applications

1. Automotive Gateway: Central gateway, domain gateway, CAN‑FD/LIN/Ethernet message routing and security encryption processing (main target application for this part)

2. Body Control Module (BCM): Control of vehicle lights, windows, door locks, rear‑view mirrors, wipers, air‑conditioning panels and PEPS Passive Entry Passive Start systems

3. Door domain ECUs, seat ECUs, ambient‑light controllers and peripheral control units for smart cockpit

4. Low‑voltage auxiliary electronics for new‑energy vehicles: DC‑DC management, low‑voltage power distribution, charging port signal management

 Other Applicable Scenarios

 Not Suitable For
