4.6.9.2 Design Layout Recommendations

When designing the LCD interface, consider the following recommendations:

  • Match the LCD signal lengths to within 50 mils. Affected PIOs in the example above are PC10 to PC27, PC30, PC31, PD0 and PD1.
  • Place the clock line (PD0) at least 3 times the trace width away from other signals for noise immunity.
  • Place data signals at least 2 times the trace width away from any other data trace.
  • Design data signals at least 2 times the trace width away from any copper plan.
