Does the Newly Purchased Chip Need to be Programmed?

09/10/2021 11:30 PM

Does the newly purchased cp2102 and CH340 need to be programmed?

I want to design a USB to TTL circuit, but I don't know which one is better. The most important thing is, do I need to write the initial program for the CP2102 and CH340 chips that I just bought? Thanks!

It would be best to initially purchase the evaluation kit for these parts since that will make it easier to get started versus buying only the chip.

The SiLabs kit is CP2102N-MINIEK No firmware development is needed for the SiLabs part. You will need the USB drivers downloaded to the target computer to communicate with the USB ports.

The cost is U.S. $7.99 from Digi-Key

Then read through the CP2102 Evaluation Kit User's Guide

https://www.silabs.com/documents/public/user-guides/CP2102-EK.pdf

and the CP2102 data sheet

The CH340 is also available through Digi-Key for U.S. $7.95

No programming required. Download drivers to your P.C., connect and run.

My preference would be for the Silicon Labs part because SiLabs appear to have better development support for their part.

Good luck with your quest.
