PRODUCTION DATA.
An external power supply must be used to supply 3.3 V to VDDIO, VDD3VFL, VDDOSC, and VDDA and to provide 1.2 V to VDD. The internal VREG is not supported; therefore, the VREGENZ pin must be tied high to 3.3 V. The supplies should ramp to full rail within 10 ms. Table 4-3 shows the supply ramp rate.
