Note:

1. The Power Consumption Considerations 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).

3. Periodically sampled and not 100% tested

4. TJ = –40°C to 115°C for 150 MHz; TJ = 0°C to 100°C for 181 MHz; CL=50pF
