The AC characteristic test conditions are as follows:
The output load circuit is shown in figure 21.83.
CL is the total value, including the capacitance of the test jig, etc. The capacitance of each pin is
as follows:
30 pF: CKIO, A24–A0, D31–D0, BS, RD, CS4–CS0, DQMUU/WE3–DQMLL/WE0, CAS3–CAS0,
50 pF: All other pins
IOL and IOH values are as shown in table 21.3, Permissible Output Currents.
Input/output signal reference level: 1.5 V (Vcc = 3.3 to 3.6 V)
Input pulse level: Vss to 3.0 V (Vss to Vcc for RES, TRST, EXTAL, CKIO, MD0–MD4, and
NMI)
Input rise/fall time: 1 ns
