1. Automotive-Grade Wide-Temperature Robust Architecture Fully qualified to AEC-Q100 Grade1 for continuous operation from -40℃ to +125℃. Integrated power-on reset (POR) and hardware fail-safe circuits for high-temperature, high-interference engine compartment environments. 2. Native Integrated CAN 2.0B Hardware Controller Full built-in CAN bus hardware supporting up to 1Mbps baud rate with 15 independent message objects. No extra external logic required, greatly simplifying peripheral circuit design of automotive ECUs. 3. High-Precision Multi-Channel Analog Acquisition Unit 8 multiplexed analog input channels with 10-bit sampling resolution, directly sampling pressure, temperature, voltage and current sensor signals, equipped with on-chip noise suppression filter. 4. Abundant PWM Motion Control Peripherals Timer2 integrates 4 independent capture/compare channels to output multi-channel complementary PWM waveforms, suitable for closed-loop control of fuel pumps, solenoid valves and small DC motors. 5. Multi-Stage Low-Power Modes with Remote Wake-Up Supports Idle mode and Power-Down deep sleep mode; remote wake-up can be triggered by external interrupt or incoming CAN message to drastically cut quiescent standby power of automotive devices. 6. Complete Fault & Safety Monitoring Mechanism Independent 15-bit watchdog timer, oscillator fault detection and under-voltage lockout reset. Auto-reset triggers upon program runaway or clock abnormality, meeting basic functional safety requirements for vehicle control units. 7. Large-Capacity Cost-Effective OTP Program Storage 32KB one-time programmable OTP memory delivers lower firmware mass-production cost than Flash; embedded lockable unique device ID for full product traceability management.
