W55MID50 Data Sheet
General Description
Winbond MFID^WB (Magnetic Field
Identification) series 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.
W55MID50 is one of series in Winbond
MFID^WB family that supports multi-functional Reader
solution and especially focus on toy, security, and
consumer related applications. The applications with
Winbond MFID^WB Tag series such as W55MID10 that
provides read-only mask ROM-ID version transponder
for mass production solution in toy industrial,
meanwhile W55MID15 provides the other solution for
manufacture option, which is 243 bonding-ID selection
transponder. Besides the single tag transponder
application, W55MID35 offers multi-transponder
recognition function for intelligent and smart toy
applications.
W55MID50 provides a wide variety of
applications for toy, security, and consumer market
meanwhile the W55MID50 is the most cost effective
solution on current MFID^WB related application market.
