TAIPEI, October 28, 2024 /PRNewswire/ — ARTERY recently announced the launch of its high-performance AT32M412/M416 microcontroller, specifically designed for motor control, providing an ideal solution for transportation tools, home appliances and industrial control applications.
With the rapid growth of global industrial automation, smart home devices and power tools, there is an increasing demand for efficient and precise motor control chips. The AT32M412/M416 series aims to meet this demand, integrating a rich range of peripherals and delivering high-speed computing performance.
Powerful Computer science Improved performance and storage efficiency
The AT32M412/M416 is powered by a high-performance ARM® Cortex®-M4 core running up to 180 MHz. Equipped with a single precision floating point unit (FPU) and digital signal processor (DSP), it provides sufficient processing power for motor applications. The MCU offers 64 KB to 128 KB of Flash memory, 16 KB of SRAM and a 1 KB OTP data storage area. The onboard memory includes a secure area for code execution protected by sLib, enabling secure operation and low consumption, which simplifies system design and improves flexibility.
Comprehensive features and peripheral resources for various control needs
The AT32M412/M416 series microcontrollers integrate rich peripherals to meet the diverse functional and connectivity requirements of motor applications. These include four operational amplifiers (OP, supporting PGA mode), two comparators (CMP), two USARTs, two I²Cs, two SPI/I²S interfaces, an advanced PWM timer designed for motor control, five timers 16-bit general purpose, two base timers, two 12-bit ADCs with 18 external channels (sample rates up to 2.5 Msps), two DACs and up to 46 fast GPIO ports. The AT32M412 supports CAN bus, while the AT32M416 offers an upgrade to CAN-FD, meeting higher standards for industrial control applications.
Additionally, OPs feature input protection circuits capable of handling high-voltage inputs, thereby simplifying external MOSFET current sampling circuits. The two ADCs with 18 external channels each have independent data sampling registers. The advanced timer supports dual brake inputs and bi-directional braking functionality, ensuring rapid response to exceptional events to protect circuits or motors.
Flexible packaging options for wide application scenarios
The AT32M412/M416 series (eight models) is available in four package options: TSSOP24, QFN32, LQFP32 and LQFP48. The device operates in an industrial grade temperature range of -40°C to 105°C, with a supply voltage of 2.4V to 3.6V. It provides precise and efficient control for motors simple DC motors, stepper motors, as well as complex brushless DC motors (BLDC) and permanent magnet synchronous motors (PMSM), making it particularly suitable for electric scooters, motorcycles, electric bicycles, washing machines, compressors, inverters, industrial fans, servo motors and power tools.
A complete engine development ecosystem to increase development efficiency
ARTERY offers a complete motor development ecosystem, including user-friendly hardware and software tools such as AT-START-M412/M416 motor development board, AT-MOTOR-EVB motor development board and AT-MOTOR-EVB motor development board. electric bike AT32M412. Coupled with a library of motor control algorithms for PMSM (BLDC) motors and support for AT-Link or third-party debuggers, the ecosystem is designed to drive BLDC motors, current synchronous motors alternating and asynchronous motors. The ecosystem also includes free motor monitoring software with a user-friendly interface for real-time monitoring of motor parameters, status and dynamic waveform displays, simplifying online debugging, accelerating development processes and reducing time to market for motor control products.
Currently, AT32M412 and AT32M416 series products are available for samples and mass production.
