AC/DC PARAMETERS
These tables describe the AD and DC parameters
of the PSD:
❏

–
Power-down and Reset Timing
The following are issues concerning the parame-
ters presented:
–
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 35 and 36 show 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.’
