DIGITAL CHARACTERISTICS
•
Min / Max characteristics and specifications are guaranteed over all operating conditions.
•
Typical characteristics and specifications are measured at nominal supply voltages and TA = 25 °C.
•
VA+ = 5 V ±5% VD+ = 3.3 V ±5% or 5 V ±5%; AGND = DGND = 0 V. All voltages with respect to 0 V.
•
MCLK = 4.096 MHz
Notes:
7.
All measurements performed under static conditions.
8.
If external MCLK is used, then the duty cycle must be between 45% and 55% to maintain this specification.
9.
The frequency of CPUCLK is equal to MCLK.
10.
V
OL
and V
OH
are
not specified under this condition.
