– Power-down and Reset Timing
In the DC specification the supply current is
given for different modes of operation. Before
calculating the total power consumption,
determine the percentage of time that the PSD
is in each mode. Also, the supply power is
considerably different if the Turbo Bit is '0.'
The AC power component gives the PLD, Flash
memory, and SRAM mA/MHz specification.
Figure 31 shows the PLD mA/MHz as a function
of the number of Product Terms (PT) used.
In the PLD timing parameters, add the required
delay when Turbo Bit is '0.'
