Hello,

I want to transfer data with a MMC card. What is the maximum speed in Mhz of SPI bus on STR710 chip? Thank you 🙂

I want to know the maximum BSPI bus speed in master mode (in Mhz).

Thanks

Hi,

Each of the two SPIs allow full duplex, synchronous communications with external devices, master or slave communication at up to 5.5Mb/s in Master mode and 4 Mb/s in Slave mode. Hich :p

Thank you very much, but I want to know the max speed of BSPI bus in Mhz.

-> APB1 /6 in master mode = X Mhz ?

Hich :p I would to have a little precision : is 4 Mb/s the maximum speed in Slave mode? Is'n it 4.096MHz ? Thanks for reply, Regards,

It looks like 4.096 mhz is the clock frequency. Did I say the clock frequency. The STR should be running at a higher speed using the PPL. Read the manual on the OSC, PPL and SPI.
