6 Power Sequencing

Before powering the F28E12x devices, no voltage larger than 0.3V above VDDIO can be applied to any digital pin, and no voltage larger than 0.3V above VDDA can be applied to any analog pin (including VREFHI). The 3.3V supplies VDDIO and VDDA should be powered up together and kept within 0.3V of each other during functional operation. The VDD sequencing requirements are handled by the device. The F2802x and F2803x devices do not have specific power sequencing requirements. For information related to any electrical specifications, see the F28E12x Microcontrollers Data Sheet.
