3.4 FAQ
Q. What "MFIDWB" means? A. "MFIDWB" Magnetic Field Identification, which is a Winbond contactless identification chip product series.
There are many application, architecture, and circuit design patented by Winbond.
Q. What different between W55MID15 and W55MID35? A. W55MID15 is a single-tag application without "Anti-collision" algorithm build-in. W55MID35 is a multi-tag
application with "Anti-collision" algorithm build-in.
Q. What is the operating frequency? A. Both W55MID15 and W55MID35 are operating on 13.553MHz ~ 13.567MHz ISM. Q. Does W55MID50 Reader IC pass FCC compliance testing? A. W55MID50 pass FCC compliance test of Section 15.209 and Section 15.225. Q. How are W55MID15 and W55MID35 IDs generated? A. W55MID15 and W55MID35 IDs are generated by manufacturing bonding option of pads RS0 ~ RS4. Q. How many W55MID15 and W55MID35 IDs are generated? A. There are total 243 bonding option IDs for W55MID15 and W55MID35. Q. How are W55MID15 and W55MID35 IDs read? A. W55MID50 is a function of MFID Reader IC. W55MID15 and W55MID35 automatically respond with its ID when
it is coupled by magnetic resonance power from Reader.
Q. Is it possible to read multiple MFIDWB chips in the same magnetic area? A. W55MID35 has been implemented by "Anti-collision" algorithm to allow more than one IDs can be simultaneously
recognized in the same magnetic area.
Q. How many W55MID35 IDs can be simultaneously read in the same magnetic area? A. Actually, there is no any limitation in total number of W55MID35 tags can be simultaneously read, if the Reader
system can provide sufficient coupled magnetic resonance power to every W55MID35 tag,
Q. Does anything interfere with MFID chip readout operation? A. W55MID series is operating on 13.553MHz ~ 13.567MHz, therefore it is far away from 27MHz and 2.45GHz.
There is no any interference with W55MIDseries.
