Part Number: DP83867IR
Hi
Problem Description
When the IC is powered on in the order of VDDIO→VDD1P0, approximately 0.2V voltage is observed flowing back from VDDIO to VDD1P0 after VDDIO rises and before VDD1P0 rises.
Please assist in confirming the following:
1. Does this behavior comply with specifications?
2. Will this situation affect the normal operation or long-term lifespan of the chip?
3. In the datasheet, the IC's power supply timing only specifies VDDA2P5 and VDDA1P8, without detailed explanations for VDDIO and VDD1P0. Is this necessary to improve?
Thanks
