Handling Transponder Megamos ID48 glass chip

[tesla80]

Hi everybody,

I want to read/write to 125khz megamos ID48 transponder glass chip. I found U2270B decoder for rfid applications.

Is there anybody who worked on this direction before to help me?

For example can I get success by using of EM4095's CCS lib?

Sincerely

Any help?

This is a website for people struggling with the CCS compiler. The reason you get no response probably is because no people on this forum have knowledge of your chip. It would help when you provide more details about it, for example that it is a crypto transponder chip used in car keys. Even better when you can post a link to a datasheet.

Having said all that, I guess you will get better response on a hardware related forum or even better, a car electronics forum. When you have more info on the compatible hardware and protocols we can help you on this forum to port the software to CCS.

Thanks for your answer.

I actually want to learn are the U2270B and EM4095 the same type chips which can do the same job?

I inspected the CCS's EM4095 driver+example and I wonder, can I use that chip and the library to write/read to the intended transponder(megamos ID48).

PS: I cannot find any detailed datasheet or application notes of U2270B which explains how to communicate with a transponder. I've found only antenna design tips..
