AWR1843: QSPI spec

KenF

Part Number: AWR1843

Hi experts,
What is clock frequency, supported frequency in STR(Single Transfer Rate), supported frequency in DTR(Double Transfer Rate)? I looked at the datasheet but was not find those specification.

Hello Vivek,

It appears Clock frequency is 40MHz. How do I calculate Supported frequency in STR(Single Transfer Rate) and DTR(Double Transfer Rate) from the table?

Ken

Hello Ken,

You can see from the timing diagrams that only single transfer rate is supported (data sent only on one of the cock edges). DTR is not supported. The transfer rate will be same as the clock frequency.

Vivek
