Power-down and RESET Timing
The following are issues concerning the parame-
ters presented:
–
In the DC specification the supply current is giv-
en for different modes of operation.
–
The AC power component gives the PLD, Flash
memory, and SRAM mA/MHz specification. Fig-
ure 56 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.'
