I need a circuit that will allow serial data transfer over a low voltage power circuit. The solution must provide both power and data transfer over 2 wires. Voltage transfer is DC and can be anywhere from 3V to 12V with a nominal current of 300mA. Current flows from one side of the link to the other only. Data transfer is bi-directional based on UART style communications and half-duplex operation. Transfer speed of 1 Mbps or more required. Very short distances - only a few CM of connection length. Need a very low component solution ideally based on a Microchip MCU.

Hello, This is quite an interesting challenge. POE is something similar, so such an approach might be beneficial. You have to understand that this sort of project is hindered by the quality of the power voltage. If you DC voltage is required to be ripple-free, then definitely tricky. Also, inserting a wave onto a flat carrier will be difficult at best. We basically need to superimpose a high-frequency wave onto the power. The higher the frequency, the easier to filter out at the power end. Do you have a cost limit in mind? Best regards, Stuart Borden.
