Take special care to minimize noise levels on the V
Using separate power planes for V
recommended. Connect the separate analog and digital power and ground planes as close as possible to
power supply outputs. If both analog circuit and digital circuit are powered by the same power supply, it is
advisable to connect a small inductor or ferrite bead in serial with both V
It is highly desirable to physically separate analog components from noisy digital components by ground
planes. Do not place an analog trace in parallel with digital traces. It is also desirable to place an analog
ground trace around an analog signal trace to isolate it from digital traces.
Because the Flash memory is programmed through the JTAG/EOnCE port, SPI, SCI or I
should provide an interface to this port if in-circuit Flash programming is desired.
