Switching Characteristics (Memory Expansion Mode and Microprocessor
Mode)
(VCC1 = VCC2 = 3 V, VSS = 0 V, at Topr = -20 to 85°C/-40 to 85°C unless otherwise specified)
5.3.4.1
In No Wait State Setting
Notes:
1.
Calculated according to the BCLK frequency as follows:
f
f(BCLK) is 12.5 MHz or less.
2.
Calculated according to the BCLK frequency as follows:
This standard value shows the timing when the output is off, and
does not show hold time of data bus.
Hold time of data bus varies with capacitor volume and pull-up
(pull-down) resistance value.
Hold time of data bus is expressed in
t =
CR × ln(1 V
OL/VCC2)
by a circuit of the right figure.
For example, when VOL = 0.2VCC2, C = 30 pF, R = 1 kΩ,
hold time of output low level is
t =
30 pF × 1 kΩ × In(1 0.2V
CC2/VCC2)
= 6.7 ns.
