Electrical Characteristics
3.6
The MAC7100 Family utilizes several pins to supply power to the oscillator, PLL, digital core, I/O ports
and ATD. In the context of this section, V

The power supply must maintain regulation within the V

the maximum injection current. The greatest risk will be when the MCU is consuming very little power (for
example, if no system clock is present, or if the clock rate is very low).

are connected by anti-parallel diodes for ESD protection.
3.6.3
All current measurements are without output loads. Unless otherwise noted the currents are measured in
single chip mode, internal voltage regulator enabled and at 40MHz bus frequency using a 4MHz oscillator
in low power mode. Production testing is performed using a square wave signal at the EXTAL input.
In expanded modes, the currents flowing in the system are highly dependent on the load at the address, data
and control signals as well as on the duty cycle of those signals. No generally applicable numbers can be
given. A good estimate is to take the single chip currents and add the currents due to the external loads.
