Read / Write Base Station IC

Description

IC for IDIC

read-write base stations

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 a bipolar integrated circuit for read-write

base stations in contactless identification and immo-

bilizer systems.

The U2270B is well suitable to perform read operations

The IC incorporates the energy transfer circuit to supply with e5530-GT and TK5530-PP transponders and also

the transponder. It consists of an on-chip power supply, an performs read-write operations with TK5550-PP and

oscillator, and a coil driver optimized for automotive- TK5560-PP transponders.
