AC/DC PARAMETERS
These tables describe the AD and DC parameters
of the device:
❏ DC Electrical Specification
The following are issues concerning the parame-
ters presented:
❏ AC Timing Specification
■ In the DC specification the supply current is
■ PLD Timing
– Combinatorial Timing
– Synchronous Clock Mode
– Asynchronous Clock Mode
given for different modes of operation. Before
calculating the total power consumption,
determine the percentage of time that the
device is in each mode. Also, the supply power
is considerably different if the Turbo bit is 0.
– Input Macrocell Timing
■ The AC power component gives the PLD and
■ DSP Timing
Flash memory a mA/MHz specification. Figure
– Read Timing
25 show the PLD mA/MHz as a function of the
– Write Timing
number of Product Terms (PT) used.
– Reset Timing
■ In the PLD timing parameters, add the required
delay when Turbo bit is 0.
