Notes:
1. The Section 3, 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
