W55MID35 DataSheet
General Description
MFIDWB (Magnetic Field Identification) is
used in all areas of automatic data capture allowing
contactless identification of objects using magnetic
field. From ticketing to industrial automation and
access control, the applications of MFID are
burgeoning. In recent years automatic identification
procedures have become very popular in many
service industries, purchasing and distribution
logistics, industry, manufacturing companies and
material flow systems.
W55MID35 is one of Nuvoton MFIDWB
(Magnetic Field Identification) series in WinRFWB
family that focus on toy and consumer related
applications. W55MID35 offers multi-transponder
recognition function for intelligent and smart toy
applications. Regarding the MFIDWB Reader series,
the W55MID50 supports multi-functional MFIDWB
Reader solution.
W55MID35 provides total up to 243
different bonding-ID options in manufacture and
10-bit ID length in each bonding option ID. For
some of applications that need more than 243 ID, it
can be bonding up to 8 tags together to gain more
IDs. Till now the W55MID35 is the most cost
effective solution on current anti-collision MFID
transponder market.
