Simple and cheap measurement of FRAM current consumption and performance data

For less than 30 US$ a precise supply current measurement of FRAM microcontrollers MSP430FR5739 can be realized with a MSP-EXP430FR5739 experimenter board and three cheap resistors using the internal analogdigital converter. This can be combined with an evaluation of the dependency of microcontroller performance data on programming structures due to distribution of code between cache, FRAM and SRAM.
