AC/DC PARAMETERS
These tables describe the AD and DC parameters
of the uPSD323X 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 72 and 73 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.'
