† Thecurrentmeasurementsweretakenwiththefollowingnominalconditions:CVDD=1.8V,DVDD=3.3V,temperature=25C,withtheDSPexecuting

programcode from internal SRAM consisting of 50% NOP / 50% MACD instructions @ 100 MHz, and the ARM executing dhrystone program code

from external SRAM @ 47.5 MHz. Actual operating current varies with program being executed and external pin usage.
