CS81 Series

AC characteristics

*1 : Delay time

= propagation delay time, enable time, disable time

*2 : “typ” is calculated based on the cell specifications.

*3 : Measurement conditions.

Note : tpd max is calculated according to the maximum junction temperature (Tj) .

■ INPUT/OUTPUT PIN CAPACITANCE

Note : Capacitance varies according to the package and the location of the pin.

■ DESIGN METHOD

SCCAD2 is the standard cell integrated design environment providing three major functions, enabling high-

quality, large-scale system LSIs to be developed in a shorter period of time. They include: the timing driven

layout function for automatic placement/routing based on timing constraints to prevent timing problems after

layout, the function for shortening the development cycle time by dividing a large-scale circuit and performing

simultaneous logical/physical design of multiple circuits, and the function for automatically generating power/

signal wiring patterns while evaluating the supply voltage drop, signal noise, delay penalty, and crosstalk (Contact

your nearest Fujitsu office for more information and availability).
