Preliminary Information
PSD9XX Family

AC/DC
Parameters
The following tables describe the AD/DC parameters of the PSD9XX family:
J
DC Electrical Specification
J
AC Timing Specification
PLD Timing
– Combinatorial Timing
Microcontroller Timing
– Read Timing
– Write Timing
– Power Down and Reset Timing
Following are issues concerning the parameters presented:
J
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".
J
The AC power component gives the PLD, Flash memory, and SRAM mA/MHz
specification. Figure 26 shows the PLD mA/MHz as a function of the number
of Product Terms (PT) used.
J
In the PLD timing parameters, add the required delay when Turbo bit is "OFF".
