Ensure that capacitor leads and associated printed circuit traces that connect to the chip V
are less than 0.5 inch per capacitor lead.
Bypass the V
capacitor such as a tantalum capacitor.
Because the controller’s output signals have fast rise and fall times, PCB trace lengths should be minimal.
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 VREF, V
Designs that utilize the TRST pin for JTAG port or OnCE module functionality (such as development or
debugging systems) should allow a means to assert TRST whenever RESET is asserted, as well as a means
to assert TRST independently of RESET. TRST must be asserted at power up for proper operation. Designs
that do not require debugging functionality, such as consumer products, TRST should be tied low.
Because the Flash memory is programmed through the JTAG/OnCE port, designers should provide an
interface to this port to allow in-circuit Flash programming.
