3.5 W55MID50 Data Sheet Document History
Winbond Electronics Corp.
application with "Anti-collision" algorithm build-in.
"MFID
W55MID15 is a single-tag application without "Anti-collision" algorithm build-in. W55MID35 is a multi-tag
Both W55MID15 and W55MID35 are operating on 13.553MHz ~ 13.567MHz ISM.
W55MID50 pass FCC compliance test of Section 15.209 and Section 15.225.
W55MID15 and W55MID35 IDs are generated by manufacturing bonding option of pads RS0 ~ RS4.
There are total 243 bonding option IDs for W55MID15 and W55MID35.
W55MID50 is a function of MFID Reader IC. W55MID15 and W55MID35 automatically respond with its ID when
W55MID35 has been implemented by "Anti-collision" algorithm to allow more than one IDs can be simultaneously
Actually, there is no any limitation in total number of W55MID35 tags can be simultaneously read, if the Reader
W55MID series is operating on 13.553MHz ~ 13.567MHz, therefore it is far away from 27MHz and 2.45GHz.
