MOTOROLA
Technical Data
1.6.1 VDD and VSS
V
DD and VSS are the power supply and ground pins. The MCU operates
from a single 3.0-V to 6.0-V power supply.
Very fast signal transitions occur on the MCU pins, placing high
short-duration current demands on the power supply. To prevent noise
problems, take special care to provide good power supply bypassing at
the MCU. Place bypass capacitors as close to the MCU as possible, as
Figure 1-3. Bypassing Layout Recommendation
1.6.2 OSC1, OSC2, and PB1/OSC3
The OSC1, OSC2, and PB1/OSC3 pins are the control connections for
the 2-pin or 3-pin on-chip oscillator. The oscillator can be driven by any
of these:
Crystal
Ceramic resonator
Resistor-capacitor (RC) combination
External clock signal
The frequency of the internal oscillator is fosc. The MCU divides the
internal oscillator output by two to produce the internal clock with a
frequency of fop.
