• Manufacturer Part Number: PEB20534H-10
• Description: DMA Supported Serial Communication Controller with 4 Channels DSCC4
• Manufacturer: SIEMENS [Siemens Semiconductor Group]

V
During all DSCC4 power-up and power-down situations the difference |
may not exceed 3.6V. The absolute maximums of V
exceeded.
Figure 83 shows that both V
the maximum slew rate for V
of 3.6V, for up to 50 milliseconds at power-up and power-down.Within 50 milliseconds of
power-up the voltages must be within their respective absolute voltage limits. At power-
down, within 50 milliseconds of either voltage going outside its operational range, the
voltage difference should not exceed 3.6V and both voltages must be returned below
0.1V:

Within the grey boxes any shape of V
limits of each signal are not exceeded, the slew rate recommendation for V
boundary scan reset and the voltage difference does not exceed 3.6V.
