• Manufacturer: STMICROELECTRONICS [STMicroelectronics]

Preliminary
AC/DC
Parameters
Figure 33. PLD I
The following tables describe the AD/DC parameters of the PSD813F1 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 PSD813F1 is in each mode. Also, the supply power is considerably different if the
Turbo bit is "OFF".
The AC power component gives the PLD, EPROM, and SRAM mA/MHz specification.
Figures 33 and 33a 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
