Latest Updated:06/12/2009

Question:

What values of external capacitance can be added to the ports ?

Answer:

(1) CMOS3 State I/O Ports
When adding external capacitance, select approximately 30 pF (*Note).

*Note:
Value used during measurement of timing characteristics by Renesas.
Please perform evaluations for your system to determine an appropriate capacitance for your system.

(2) Input-only Ports
There are no special restrictions on these ports. Select the capacitance according to the characteristics of the externally connected circuit.
