W55MID35 DataSheet
2.2 W55MID35 Functional Description
External Inductor Coupling Circuit
The external inductor coupling circuit is designed for 13.56MHz magnetic field resonatnce. The coupled
center frequency will depend on equivalent inductor of external PCB inductor and a paralleled capacitor.
Voltage Regulator & System Power Supply
The voltage regulator generates the need of device power supply.
Power-On Control Circuit
System power-on control circuit initiates the device to get into initial state.
Demodulation Control Circuit
The demodulation control circuit demodulates the signal of command, which is magnetic field coupling
from W55MID50 MFID^WB Reader system.
System Clock Generator
The system clock generator generates the need of device system clock.
Bonding-ID Decoder
The Bonding-ID decoder circuit decodes the mapping location of IDs array, which indicates by external
RS0, RS1, RS2, RS3, and RS4 the 3-state Bonding Finger (Nuvoton patented).
Multiple Bonding-ID Recognition
The multiple Bonding-ID recognition provides total up to 8 different customer-IDs and 10bit ID length
can be recognize in the same time.
Data Format and Framing Generator
The data format and framing generator is in charge of the entire bonding-ID and command data into
Nuvoton defined MFID^WB transponder data format.
Modulation Control Circuit
The modulation control circuit modulates the Nuvoton defined MFID^WB tag format into the magnetic field
resonati
