U2270B General Description
IC for IDIC® *) read-write base stations
The U2270B is a bipolar integrated circuit for read-write base stations in contactless identification and immobilizer 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 IC for IDIC[ *) read-write base stations
The U2270B is a bipolar integrated circuit for read-write base stations in contactless identification and immobilize 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 automotivespecific 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.
