µPSD325X DEVICES
AC/DC PARAMETERS
These tables describe the AD and DC parameters
of the µPSD325X devices:
§ DC Electrical Specification
§ AC Timing Specification
s
PLD Timing
– Combinatorial Timing
– Synchronous Clock Mode
– Asynchronous Clock Mode
– Input Macrocell Timing
s
MCU Module Timing
– READ Timing
–WRITE Timing
– Power-down and RESET Timing
The following are issues concerning the parame-
ters presented:
s
In the DC specification the supply current is
given for different modes of operation.
s
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.
s
In the PLD timing parameters, add the required
delay when Turbo Bit is '0.'
