At CES 2016, major chip makers and equipment manufacturers launched an air battle, making the emerging form of drones a real fire. The reason is that if drones have been positioned in personal consumer applications, it The market capacity is actually very limited, and the enthusiasm of the manufacturers will not be so high. However, 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 non-network small series can be quite proud, because domestic companies such as DJI, Yihang and other companies rely on the keen market sense to seize the opportunity to let domestic manufacturers In this market, it 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 STM32 F0/F1/F2/F3/F4/F7/L0/L1/L4 multiple product series, among which STM32 F4 series is widely used in drones.
The ARM Cortex-M4-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 by far all Cortex-based The highest benchmark score achieved by the M-core microcontroller product.
Due to the dynamic power scaling feature, the current consumption through flash memory ranges from 89 μA/MHz for the STM32F410 to 260 μA/MHz for the 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 – 180 MHz CPU/225 DMIPS, up to 2 MB of dual-zone flash with SDRAM and QSPI interface, Chrom-ART AcceleratorTM, LCD-TFT controller and MPI-DSI interface
• STM32F429/439 – 180 MHz CPU/225 DMIPS, up to 2MB of dual-zone flash with SDRAM interface, Chrom-ART AcceleratorTM and LCD-TFT controller
• STM32F427/437 – 180 MHz CPU/225 DMIPS, up to 2 MB of dual-zone flash with SDRAM interface, Chrom-ART AcceleratorTM, serial audio interface for higher performance and lower static power consumption
Basic series
• STM32F446 – 180 MHz/225 DMIPS, up to 512 KB Flash with Dual Quad SPI and SDRAM interfaces
• STM32F407/417 – 168 MHz CPU/210 DMIPS, up to 1MB of Flash, adds Ethernet MAC and camera interface
• STM32F405/415 – 168 MHz CPU/210 DMIPS, up to 1MB of Flash, advanced connectivity and encryption
Basic series
• STM32F411 – 100 MHz CPU/125 DMIPS with superior power efficiency, larger SRAM and new intelligent DMA to optimize data batch power consumption (dynamic efficiency series in batch acquisition mode)
• STM32F410 – 100 MHz CPU/125 DMIPS, setting a new milestone for superior power efficiency performance (89 μA/MHz and 6 μA in shutdown mode), optimized for data batch processing with new intelligent DMA (using batch Acquisition Mode Dynamic EfficiencyTM Series) with True Random Number Generator, Low Power Timer and DAC
• STM32F401 – 84 MHz CPU/105 DMIPS, the smallest, lowest cost solution with superior power efficiency (dynamic efficiency series)
