I have in use the tms3705a from ti. You can find informations about this at h**p://w*w.ti.com/tiris/default.htm. In my opinion there are very few (free) information on the internet about this theme (you have almost always to sign NDA's before they give you details - and even then they give you only that information you are asking about - it's mystical...)
Hi, I build the reader circuit in TK5552 AN.However I can not observe any signals in input or output pin of the u2270B.I can not find more information about the u2270.Do I have to write some data to transponder firstly?Can you draw me way for the procedures of transponder Tk5551/52 and u2270B please?
Do you have asm code for the microcontroller to read manchester code from the U2270B IC. Can you tell me also where i can get the EMMarin Transponder card? I seems can't find it anywhere. Hope to hear from you soon. Thanks.
