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. Figures
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.’
