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.'
