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
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, QSPI, QSCI, or I
designer should provide an interface to this port if in-circuit Flash programming is desired
If desired, connect an external RC circuit to the RESET pin. The Resistor value should be in the range of
4.7k—10k; the Capacitor value should be in the range of 0.22µf - 4.7µf.
Add a 3.3k external pull-up on the TMS pin of the JTAG port to keep EOnce in a restate during normal
operation if JTAG converter is not present
During reset and after reset but before I/O initialization, all I/O pins are at input state with internal pull-up
enable. The typical value of internal pull-up is around 110K. These internal pull-ups can be disabled by
software.
To eliminate PCB trace impedance effect, each ADC input should have a 33pf-10 ohm RC filter
Device GPIOs have only a down (substrate) diode on the GPIO circuit. Devices do not have a positive clamp
diode because GPIOs use a floating gate structure to tolerate 5V input. The absolute maximum clamp
current is -20mA at V
voltage spikes are a concern, a positive clamp is recommended.
