Spi flash speed
WebSep 22, 2014 · However I would like to know where can I get the information on the maximum clock frequency (I can drive my SPI bus) for the given SD card. I have seen that for some SD cards maximum speed was about 1.33MHz and for some 20MHz. I assumed this speed was in the CSD register (TAAC value, as the TRAN_SPEED was the same on all the … WebAug 12, 2024 · NOR Flash - This is overwhelmingly accessed using SPI, even on smaller and slower Flash chips. Slower chips are available that can be accessed with I2C. ... This includes memory chips, although if the controller is only using I2C and the memory is using SPI then the speed might be limited and the receiving component might not work due to …
