Hi AURIX Community,

Do you know how long does it take to access data from the memory like program flash, sram & peripherals on AURIX TC2xx?

Thank you
Lucas

Hi Lucas,

The user manual has a chapter On Chip Bus Master TAG Assignments that shows access times in CPU clock cycles for the different memory locations.

Of course these numbers represent the ideal case and can be bigger in applications with many accesses on the bus in parallel due to arbitration.

The table gives a hint where code and could be located, of course this depends on the application use case.

Best regards

Mr. AURIX™
