16. Dynamic characteristics
[1]
[2]
Recommended accuracy of the clock frequency is 500 ppm for the crystal and oscillator. The oscillator should have 3.3 V power supply.
Suggested values for external capacitors when using a crystal are 22 to 27 pF.
[1]
[2]
All pins are 5 V tolerant.
The bus capacitance (C
B
) is specified in pF. To meet the specification for V
OL
and the maximum rise time (300 ns), use an external
pull-up resistor with R
max
= 850/C
B
k
and R
min
= (V
DD

.

[2]
All pins are 5 V tolerant.
Standard load is 10 pF together with a pull-up and pull-down resistor of 10 k
.
