minimum of 2.0 V for all pins. AC timing specifications, which are referenced to a device input signal, are measured in

production with respect to the 50% point of the respective input signal’s transition. For all pins, output levels are measured with

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 (for example, 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 with Fsys < 200 MHz is

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

to float).
