AC/DC PARAMETERS

The tables provided below describe the AD and

DC parameters of the PSD:

–WRITE Timing

–

Peripheral Mode Timing

–

Power-down and Reset Timing

The following are issues concerning the parame-

ters presented:

–

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 PSD

is in each mode. Also, the supply power is

considerably different if the Turbo Bit is '0.'

–

The AC power component gives the PLD,

Flash memory, and SRAM mA/MHz

specification. Figure 34 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 '0.'
