MSP430FR5859: About the current consumption when device is in active mode

Hi Uchida-K,

Uchida-K said:

1.Do you have any information about the temperature characteristics of current consumption when device is in active mode?

   I can't find that in the datasheet.

The currents listed in Section 5.4 of the datasheet are representative of the entire recommended operating temperature range for this device (-40C to 85C). We don't have temperature graphs depicting this data.

2.Could you tell me how to find out how much cache hit ratios are listed on page 18 of the datasheet In my code?

Take a look at this thread:

3.Could you please give me code examples that hit rate of cache is 25%, 50%, 75% respectively?

Unfortunately, we don't have code examples showing specific cache hit ratios. I would recommend creating your code and working backward by looking at the device datasheet to determine your cache hit ratio.

Hi Caleb Overbay,

Thank you for your reply.

I am planning to measure the current consumption with the following sample code.

msp430fr59xx_active_01.c

There is "typical cache hit ratio" in the explanation of this sample code.
Could you tell me what percentage is?
