PSD9XX Family
Figure 27. PLD I CC /FrequencyConsumption
The following tables describe the AD/DC parameters of the PSD9XX family:
Following are issues concerning the parameters presented:
DC Electrical Specification
AC Timing Specification
•
•
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 PSD9XX is in each mode. Also, the supply power is considerably different if the
Turbo bit is "OFF".
The AC power component gives the PLD, Flash memory, and SRAM mA/MHz
specification. Figures 27 and 27a 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 "OFF".
PLD Timing
– Combinatorial Timing
Microcontroller Timing
– Read Timing
– Write Timing
– Power Down and Reset Timing
