Electrical Design Considerations
56F8035/56F8025 Data Sheet, Rev. 6
Freescale Semiconductor
157
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 VDD and VSS circuits.
Take special care to minimize noise levels on the VREF, VDDA, and VSSA pins
Using separate power planes for VDD and VDDA and separate ground planes for VSS and VSSA are
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 VDDA and VSSA traces.
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 I2C, the
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 0.22f - 4.7f.
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 Vin less than 0V. The continuous clamp current is -2mA at Vin less than 0V. If positive
voltage spikes are a concern, a positive clamp is recommended.
