Artery MCUs power the intelligent transformation of electric two-wheelers.

Electric two-wheelers, as an economical and eco-friendly means of short-range mobility, have become indispensable for personal commuting, food-delivery fleets and shared-mobility programs. Under the dual impetus of China’s new national standard and the smart-mobility wave, their electronic control units (ECUs) must now deliver high-efficiency powertrains, safety protection and extended range simultaneously. In traditional architectures the controller—literally the “vehicle brain”—must execute motor speed regulation, battery management and human-machine interaction in real time, posing three challenges for the host MCU:

• Sub-microsecond real-time response (e.g., PWM edge resolution down to 6.9 ns)

• Support for complex algorithms (FOC vector control, battery SOC estimation)

• Rugged-environment reliability (-40 °C to 85 °C, 50 g vibration)

MCUs, thanks to their highly integrated architecture, have emerged as the optimal choice. A single chip combines CPU, memory, analog peripherals and hardware accelerators, cutting PCB area by 30 % versus discrete solutions and shrinking interrupt latency to the micro-second range via hardware-level task scheduling. For example, Nationstech’s N32 series, with four independent 5 Msps ADCs and a quadrature-encoder interface, enables synchronous phase-current acquisition and commutation, pushing energy-conversion efficiency above 92 %.

M4-core MCUs strike the perfect balance between performance and energy efficiency, driven by three technological leaps:

• Instruction-set evolution: Arm Cortex-M4 adds DSP instructions and a hardware FPU, running at 120–200 MHz and tripling algorithmic throughput versus M0/M3. A full FOC loop—Clarke/Park transform plus SVPWM—completes in 20 µs, keeping torque ripple below 2 % and eliminating the “jerk” of trapezoidal control.

• Breakthrough energy efficiency: Dynamic voltage scaling down to 1.8 V, combined with multi-level sleep modes (Stop current < 2 µA), adds ~15 % battery life. Geehy’s APM32F035 leverages PASR memory refresh to cut BMS standby current to 0.8 µA, ideal for shared vehicles left idle for days.

• Comprehensive interface ecosystem: Native CAN, USB and Ethernet with automotive-grade protocols. Nationstech’s N32G430 uses CAN-FD to synchronise controller and dashboard data within 100 µs, while a built-in AES-256 engine secures OTA updates.

Artery AT32F421G4U7: the benchmark “value-line” MCU

The AT32F421G4U7 redefines electric-two-wheeler control by delivering automotive-grade performance at consumer-grade cost. Based on a 120 MHz Cortex-M4, it offers 64 KB Flash and 16 KB SRAM in a 4 mm × 4 mm QFN-28 package. Key metrics versus competing parts:

An sLib security library enables IP-protected firmware: motor-control algorithms can be pre-burnt while customers add UI layers without exposing core know-how. Value is unlocked across three usage scenarios:

Precision motor control: hardware MAC accelerates FOC; single-shunt current sensing removes three op-amps and saves ~USD 0.80 BOM.

Smart BMS: dual ADCs sample 16 cell voltages concurrently, giving SOC estimation accuracy of ±3 % with coulomb counting.

Next-gen HMI: SPI-driven TFT displays enable navigation mirroring and visual diagnostics.

As Artery’s authorised distributor, Mando Technology offers closed-loop support:

• Pin-compatible migration from N32, Geehy and other platforms with a 48-hour hardware-migration guide.

• Free samples qualified over –40 °C to 125 °C thermal cycling, 50 g random vibration and EMC immunity testing.

• Production-grade motor-control libraries and encrypted OTA firmware shorten development cycles by 30 %.

In the critical phase where electric two-wheelers evolve toward “intelligent, long-range and ultra-safe”, the AT32F421G4U7 embodies the DNA of “performance headroom, cost extremism and ecosystem openness”. Its China-designed supply chain delivers 25 % lower pricing and stable four-week lead times, eliminating geopolitical risk. Mando’s local service network further empowers innovation—an in-house failure-analysis lab pinpoints rotor-position-detection deviations, and a dedicated motor-control team provides PID tuning and vibration-damping solutions to inject every two-wheeler with the ultimate riding experience: silky start-up, whisper-quiet operation and range anxiety-free journeys. As the new national standard drives industry consolidation and shared e-bikes surpass ten-million daily rides, choosing Artery means choosing to define the next decade of two-wheeled mobility with “value without compromise.”
