To meet the demands of low development budgets, Artery has launched the AT32F421 value line Cortex®-M4 MCU at a price comparable to the Cortex®-M0. Since its official release in September 2020This series of MCUs enjoys a good reputation and is widely applied in fields such as motor control, industrial automation, IoT, and home appliances.
Hsinchu, October 26, 2022 /PRNewswire/ — on October 21stARTERY Technology has launched the brand new AT32F4212 series value-line Cortex®-M4 MCU, which is designed with dual integrated operational amplifiers (OPAs) based on AT32F421 MCU, effectively simplifying circuit design and saving material costs . With current amplification and short circuit protection, OPA can be used for current sensing, field oriented control (FOC) or line current sensing to determine if a fault (e.g. locked rotor) has occurred (if If so, shut it down). time to prevent hardware damage). In addition, it has high open source gain, high input impedance, low output impedance, provides excellent low-level signal, and outputs high voltage and large current to drive various loads, so it can be used for power tools, gardening machines, E-bikes, washing machines, UAVs, mechanical arms, high-speed air ducts, vacuum cleaners, exhaust fans, kitchen extractors and other powered applications.
The AT32F4212 inherits the outstanding performance of the AT32F421, with a CPU up to 120 MHz, high-speed embedded memory (up to 64 KB Flash and 16 KB SRAM), and an embedded Digital Signal Processor (DSP). It is the most cost-effective MCU product on the market today, it can be used with 2.4~3.6V power supply at -40~105°C operating temperature, meeting the requirements of low power applications in low power mode.
AT32F4212 Series MCUs
The AT32F4212 series MCUs are designed with a rich set of interfaces to enhance connectivity, including 2 USARTs, 2 SPI (multiplexed I²S), 2 I²C, 1 16-bit advanced timer, 5 16 It incorporates a bit general-purpose timer, and a 5-channel DMA controller. Such abundant on-chip resources, high degree of integration, and high cost performance make the AT32F4212 MCU’s core competitiveness. In addition, ARTERY has extended two high-speed rail-to-rail input/output analogy voltage comparators, one 12-bit 2 MSPS ADC (including 12 external channels and 5 internal channels), and two OPAs. Velocity data acquisition, mixed signal processing, industrial control, and motor applications. The AT32F4212 series also provides high-speed I/O, nearly 5 V tolerant, and port remapping support, giving users more flexibility for application solutions such as motor control, healthcare devices, IoT nodes, industrial automation, and security. and convenient to develop. , home appliances, electronic toys, robots.
Artery AT32F4212 series MCUs improve and replace traditional Cortex®-M0/M3 product solutions, import Cortex®-M4 based high-speed mainstream platform, developed by ARTERY Technology and pre-defined security library (sLib) is designed to contain A code-protected region in main memory. Solution providers can program core algorithms into this area for secondary development. It enhances the safety, reliability and convenience of the secondary development of AT32F4212 series MCUs, with the advantages of low cost, high energy efficiency and flexibility. The AT32F4212 series MCUs are offered in an LQFP48 7×7 package and samples are available at: October 2022.
