At CES2016, major chip makers and equipment manufacturers launched an air battle, making the emerging product form of drones a real fire. The reason is that if drones have been positioned in personal consumer applications, its The market capacity is actually very limited, and the enthusiasm of the manufacturers will not be so high, but as its demand in other application scenarios such as agriculture and logistics is continuously explored, the enthusiasm that can sweep the upstream and downstream of the industry will naturally follow. Come. This year's CES related topics related to drones are everywhere, and Xiaobian can be quite proud of it, because domestic companies such as Dajiang and Yihang seize the first opportunity with the keen market sense, let domestic manufacturers in this block. The market is very beautiful, and also masters the important discourse power in the industrial chain. But the upstream chip suppliers in the UAV market, especially the main control chip, are still dominated by European and American Korean manufacturers. Xiaobian specially counts the current mainstream 8 UAV master control chips for your reference: 1. STMicroelectronics STM32 Series At present, STMicroelectronics' STM32 series is a high-utility drone master chip in China. At this point, STMicroelectronics has a very clever approach. It has sponsored the National Undergraduate Electronic Design Competition very early. The main control chip of the man-machine project is STM32. The students are familiar with its main control platform. After working, the drone will naturally choose it. The STM32 series has a number of STM32F0/F1/F2/F3/F4/F7/L0/L1/L4 product lines. Among them, the STM32F4 series is widely used in drones. The ARMTM-based STM32F4 family of MCUs uses ST's NVM process and ART accelerators to achieve 225 DMIPS/608 CoreMark performance through flash memory at operating frequencies up to 180 MHz, which is the basis of all Cortex-M-based cores to date. The highest benchmark score achieved by the controller product. Due to the dynamic power adjustment function, the current consumption range from flash memory execution is 89μA/MHz for STM32F410 to 260μA/MHz for STM32F439. The STM32F4 series includes eight compatible digital signal controller (DSC) product lines that are the perfect combination of MCU real-time control and DSP signal processing: Advanced series STM32F469/479–180MHz CPU/225DMIPS, up to 2MB of dual-zone flash with SDRAM and QSPI interface, Chrom-ARTAccelerator, LCD-TFT controller and MPI-DSI interface STM32F429/439–180MHz CPU/225DMIPS, up to 2MB of dual-zone flash with SDRAM interface, Chrom-ARTAccelerator and LCD-TFT controller STM32F427/437–180MHz CPU/225DMIPS, up to 2MB of dual-zone flash with SDRAM interface, Chrom-ARTAccelerator, serial audio interface for higher performance and lower static power consumption Basic series STM32F446–180MHz/225DMIPS, up to 512KB Flash with DualQuadSPI and SDRAM interfaces STM32F407/417–168MHz CPU/210DMIPS, up to 1MB of Flash, adds Ethernet MAC and camera interface STM32F405/415–168MHz CPU/210DMIPS, up to 1MB of Flash, advanced connectivity and encryption Basic series STM32F411–100MHz CPU/125DMIPS, with superior power efficiency, larger SRAM and new intelligent DMA, optimized data processing power consumption (dynamic efficiency series in batch acquisition mode) The STM32F410–100MHz CPU/125DMIPS sets a new milestone for superior power efficiency performance (89μA/MHz and 6μA in shutdown mode), and uses new intelligent DMA to optimize the power consumption of data batches (using the dynamic efficiency of batch acquisition mode)? Series) with true random number generator, low power timer and DAC STM32F401–84MHz CPU/105DMIPS, the smallest and lowest cost solution with superior power efficiency (dynamic efficiency series) 2. Qualcomm Xiaolong Flight Platform At CES2016, Qualcomm Incorporated's subsidiaries Qualcomm Technologies, Tencent and Zero Intelligence released and demonstrated a commercial drone YING based on the Qualcomm Xiaolong Flight platform, which will be available worldwide in the first half of 2016. Snapdragon Flight is a highly optimized 58x40mm development board designed for consumer drones and robotics applications. Snapdragon Flight includes a Snapdragon 801 SoC (consisting of four cores with a frequency of 2.26GHz), supporting GPS, 4K video capture, strong connectivity and advanced drone software and development tools, dual-channel Wi-Fi And Bluetooth module, support real-time flight control system, with Global Navigation Satellite System (GNSS) receiver, support 4K video processing, support fast charging technology, and all of this is integrated on a business card-sized motherboard. Bringing cutting-edge mobile technology to create a new level of consumer drones. This chip can lower the average price of 4K drones from about RMB7791 to about RMB1948-2597, and extend the battery life from 20 minutes to 45-60 minutes. Is it immediately grounded? The Opteron Flight platform has advanced processing capabilities, relying on Qualcomm HexagonDSP for real-time flight control, built-in Qualcomm 2x2 Wi-Fi and Bluetooth connectivity, and an optimized leading Global Navigation Satellite System (GNSS) to support highly accurate positioning. The purpose of the Xiaolong Flight platform is to meet the most advanced features that drone consumers want, including: 1, 4K video - support 4K high-definition camera, graphics optimization and video processing functions, as well as synchronous 720p decoding. 2.
