5. FUNCTIONAL DESCRIPTION
5.1 Transmission Power Amplifier (PA)
It provides 4 different selectable transmission power for Reader chip to support MFIDWB Tag's
radiation power supply. The external inductor coupling circuit is designed for 13.56MHz
magnetic field resonance. The coupled center frequency will depend on equivalent value of
external PCB inductor and capacitor.
5.2 Envelope Detector & Analog Front End
The major function of this unit provides MFIDWB Tag's data can be extracted.
5.3 Voltage Regulator
The voltage regulator generates the system needs of device power supply.
5.4 Configuration Register
System configuration register controls the all functional settings of W55MID50 such as Tag data
format, Tag detection cycle, output data format, and PA transmission power selection.
5.5 Reset and Power-down Control
The function of system power-down control mode is normally used for power consumption
saving.
5.6 Crystal Oscillation
The 13.56MHz system clock generator generates the need of device system clock.
5.7 Decoder NRZ/Manchester
This unit is in charge of Tag data format decoder, which can provide Tag-ID data format
decoding of NRZ or Manchester.
5.8 Data Buffer and Output
This unit buffers the Tag-ID data, which is under de-frame processing.

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. 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.
