PSD9XX Family

PSD935G2 Beta Information

AC/DC

Parameters

The following tables describe the AD/DC parameters of the PSD9XX family:

t DC Electrical Specification

t 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:

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 PSD9XX 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, 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.

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