Microcontroller firmware development for Li-Ion battery charger - repost

Firmware development for micro controller (MCU) used in high end battery charger. Thank you to the many people who applie dto the last iteration of this post, the flowchart was not ready yet. Now we are ready to go!

MCU will communicate with the fuel gauge IC inside the battery pack and will control the charger IC in the charging cradle.

MCU resides in charging cradle side.

Communication protocol must be per SMBus specifications and SBC110.

Enclosed is the final flowchart, 2 programs are required, one for "version A" and one for "Version B". The charger Schematic includes ATXMEGA64A3-AU but this Chip overuns our budget. Please review the flowcharts and schematic and suggest the lowest cost Chip complete PN you suggest to use.

We will compare all applicants suggestions and modify this post for that IC before awarding. I will award this job to at least 2 people in parallel, so it will be reported and re-awarded when we make decisions.

Start immediately. Timeline, 25 days max.

Any questions or ideas can be posted to this site or to my email.

Thanks

David

The project will be paid in Phases. Upon receipt and check of the first code of "Version A" and "Version B" we will pay a portion of the money. When the code is checked in circuit and working, the balance paid. If the code needs modification, we will need the contractor to help fix it before the final payment is made. Thanks!
