The ACM32G103 series MCU uses the M33 core, operates at 120MHz, supports floating point operations and DSP, and comes with a CORDIC trigonometric function hardware accelerator; it uses 320KB on-chip eFlash, 64KB SRAM large-capacity storage space, and comes with a Flash accelerator to achieve zero-wait access; integrated Rich analog peripherals, built-in 2 advanced timers, 2 19-channel 4Msps ADC, 1 2-channel DAC, 4 comparators, 3 operational amplifiers, meeting dual motor FOC control requirements; using OTFDEC online external storage decryption function , built-in AES cryptographic algorithm hardware acceleration engine and built-in high-quality random number generator, effectively protecting user codes from being stolen and tampered with.

ACM32G103 is a cost-effective general-purpose MCU with rich analog peripherals and secure storage expansion capabilities. It adopts M33 core, operates at 120MHz, supports floating point operations and DSP, and comes with a CORDIC trigonometric function hardware accelerator, and has excellent computing processing. capabilities and ultra-low power consumption; uses 320KB on-chip eFlash, 64KB SRAM large-capacity storage space, and comes with a Flash accelerator to achieve zero-wait access; integrates rich analog peripherals, built-in 2 advanced timers, 2-channel 19-channel 4Msps ADC , 1-channel 2-channel DAC, 4-channel comparators, 3-channel operational amplifiers, meeting the dual-motor FOC control requirements; in terms of safety, Hangxin combines its own eFlash technology in security chips and deep low-power design experience, in 103 It is the first in its category to introduce the OTFDEC online external storage decryption function, which stores codes in the form of ciphertext, decrypts and runs the code in QSPI Flash in real time, and has a built-in AES cryptographic algorithm hardware acceleration engine and a built-in high-quality random number generator to effectively protect users. Code cannot be stolen or tampered with.

Compared with 103 products of the same type, Shanghai Hangxin ACM32G103 series MCU has more advanced process and more optimized cost and production capacity.

The OTFDEC (Online External Storage Decryption) technology independently developed by Shanghai Hangxin solves the technical pain point of users requiring external storage of code and data but can only store it in plain text, effectively preventing end customers' codes and data from being cracked and leaked. Using the AES encryption algorithm to encrypt and decrypt data, there is basically no possibility of off-chip cracking.

The Shanghai Hangxin team has fifteen years of profound technical accumulation in the field of integrated circuit design, over 40 and 100 models of security + MCU chip mass production experience, fully independent forward design, and provides customers with high-quality products and services.

Shanghai Hangxin continues to build a complete development ecosystem around MCU products, provides comprehensive software and hardware development tools, supports a variety of integrated development environments IDE, and minimizes user development workload. In addition, Hangxin can work with solution providers to provide dual-motor non-inductive FOC algorithm support and debugging for specific customers, helping customers accelerate development efficiency and efficiently achieve product upgrades.

Shanghai Hangxin ACM32G103 series MCU has been widely used in brushless DC motors, encoders, DTU/LTU, charging piles, electric two-wheeled vehicles, etc., and has reached in-depth cooperation with domestic leading motor manufacturers.
