達到這速度的ARM , DSP, FPGA太多了
首先你要說說你的應用
比如聯發科的方案中的ARM都能達到這速度
FPGA自己做SPI接口也能達到
如果單純說MCU,單片機這種
STM32F40x系列的可以到42Mbit/s
The STM32F40x feature up to three SPIs in slave and master modes in full-duplex and
simplex communication modes. SPI1 can communicate at up to 42 Mbits/s, SPI2 and SPI3
can communicate at up to 21 Mbit/s. The 3-bit prescaler gives 8 master mode frequencies
and the frame is configurable to 8 bits or 16 bits. The hardware CRC generation/verification
supports basic SD Card/MMC modes. All SPIs can be served by the DMA controller.
The SPI interface can be configured to operate in TI mode for communications in master
mode and slave mode.
其餘的可能要搜一搜datasheet 或者直接問FAE |
