Electrical characteristics
For the PXD20 microcontroller, 100 nF should be placed between each V_DD12/V_SS12 supply pair and also between the
V_DDPLL/V_SSPLL pair. Additionally, 10 F should be placed between the V_DDR pin and the adjacent V_SS pin.
V_DDR = 3.0 V to 3.6 V / 4.5 V to 5.5 V, T_A = –40 to 105 °C, unless otherwise specified.
