Note:

1 The Current Consumption section provides a formula to compute the estimated current requirements in Normal

mode. In order to obtain these results, all inputs must be terminated (i.e., not allowed to float). Measurements are

based on synthetic intensive DSP benchmarks. The power consumption numbers in this specification are 90% of

the measured results of this benchmark. This reflects typical DSP applications. Typical internal supply current is

measured with VCORE_VDD = 1.25V, VDD_IO = 3.3V at TJ = 25°C. Maximum internal supply current is measured

with VCORE_VDD = 1.30V, VIO_VDD) = 3.46V at TJ = 115°C.

2 In order to obtain these results, all inputs, which are not disconnected at Stop mode, must be terminated (i.e., not

allowed to float).
