AC/DC PARAMETERS
These tables describe the AD and DC parameters
of the uPSD325X devices:
§
DC Electrical Specification
§
AC Timing Specification
I
PLD Timing
– Combinatorial Timing
– Synchronous Clock Mode
– Asynchronous Clock Mode
– Input Macrocell Timing
I
MCU Module Timing
– READ Timing
– WRITE Timing
– Power-down and RESET Timing
The following are issues concerning the parame-
ters presented:
I
In the DC specification the supply current is
given for different modes of operation.
I
The AC power component gives the PLD, Flash
memory, and SRAM mA/MHz specification.
Figure 72 and Figure 73 show the PLD mA/MHz
as a function of the number of Product Terms
(PT) used.
I
In the PLD timing parameters, add the required
delay when Turbo Bit is '0.'
