2209 - [Platform Manager 2] Does VCCD and VCCA need to be above 3.0V when programming the device since the data sheet shows that VCCPROG should between 3.0V to 3.6V?
The POWR1220AT8 will program when the VCCD and VCCA are at 2.8 Volts. The device was characterized across the entire data sheet operating range of 2.8 Volts to 3.96 Volts and this testing included programming of the device.
The voltage range for the VCCPROG was established over a range that we expected customers to use when programming the device. It was not expected that customers would need to program the device using a VCCPROG that was lower than 3.0 Volts. However, when the VCCD and VCCA were tested it was decided to open up the range and the values in the data sheet reflect this wider range over which the testing was done. The VCCPROG testing was not repeated over this wider voltage range so this is why the data sheet shows the range of 3.0 to 3.6 Volts.
