Read / Write Base Station IC
Description
IC for IDIC
*)
read-write base stations
The U2270B is a bipolar integrated circuit for read-write
base stations in contactless identification and immo-
bilizer systems.
The IC incorporates the energy transfer circuit to supply
the transponder. It consists of an on-chip power supply, an
oscillator, and a coil driver optimized for automotive-
specific distances. It also includes all signal-processing
circuits which are necessary to form the small input signal
into a microcontroller-compatible signal.
The U2270B is well suitable to perform read operations
with e5530-GT and TK5530-PP transponders and also
performs read-write operations with TK5550-PP and
TK5560-PP transponders.
