AC/DC PARAMETERS

These tables describe the AD and DC parameters
of the uPSD321x 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 parame-
ters 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. Figures

68

and

69

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.'
