Electrical Design Considerations

• 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.

• When using Wired-OR mode on the SPI or the IRQx pins, the user must provide an external pull-

up device.

• 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.
