Preliminary

PSD813F1-A

AC/DC

Parameters

The following tables describe the AD/DC parameters of the PSD813F1 family:

t DC Electrical Specification

t AC Timing Specification

• PLD Timing

– Combinatorial Timing

– Synchronous Clock Mode

– Asynchronous Clock Mode

– Input Micro

⇔Cell Timing

• Microcontroller Timing

– Read Timing

– Write Timing

– Peripheral Mode Timing

– Power Down and Reset Timing

Following are issues concerning the parameters presented:

t 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".

t 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.

t In the PLD timing parameters, add the required delay when Turbo bit is "OFF".
