Preliminary—Subject to Change Without Notice

Freescale Semiconductor

For the PXD20 microcontroller, 100 nF should be placed between each VDD12/VSS12 supply pair and also between the

VDDPLL/VSSPLL pair. Additionally, 10 F should be placed between the VDDR pin and the adjacent VSS pin.

VDDR = 3.0 V to 3.6 V / 4.5 V to 5.5 V, TA = –40 to 105 °C, unless otherwise specified.
