Section 24 Electrical Characteristics
24.3 AC Characteristics
In general, inputting for this LSI should be clock synchronous. Keep the setup and hold times for
each input signal unless otherwise specified.
Operating conditons are as follows:
VccQ = 3.3 ± 0.3V
Vcc = 1.9 ± 0.15V
Avcc = 3.3 ± 0.3V
Ta = −20 to +75°C
