12.3 Power Distribution and I/O Ring Implementation
Figure 12-1
contains two internal power regulators. One of them is powered from the V
be turned off. This regulator controls power to the internal clock generation circuitry. The other regulator
is powered from the V
peripherals and the internal memories. This regulator can be turned off, if an external V
is externally applied to the V
In summary, the entire chip can be supplied from a single 3.3 volt supply if the large core regulator is
enabled. If the regulator is not enabled, a dual supply 3.3V/2.5V configuration can also be used.

V
Consider all device loads as well as parasitic capacitance due to PCB traces when calculating capacitance.
This is especially critical in systems with higher capacitive loads that could create higher transient currents
in the V
Take special care to minimize noise levels on the V
Because the Flash memory is programmed through the JTAG/EOnCE port, the designer should provide an
interface to this port to allow in-circuit Flash programming
Flash, RAM and internal logic are powered from the core regulator output
