AC/DC parameters

These tables describe the AD and DC parameters of the UPSD33xx Devices:

●

DC electrical specification

●

AC timing specification

●

PLD timing

–

Combinatorial timing

–

Synchronous Clock mode

–

Asynchronous Clock mode

–

Input macrocell timing

●

MCU module timing

–

READ timing

–WRITE timing

–

Power-down and RESET timing

The following are issues concerning the parameters presented:

●

In the DC specification the supply current is given for different modes of operation.

●

The AC power component gives the PLD, Flash memory, and SRAM mA/MHz

specification. Figure 84 and Figure 85 on page 243 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.'
