The U2270B is an IC for IDIC 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-spe- cific distances. It also includes all signal-processing circuits which are necessary to transform the small input signal into a microcontroller-compatible signal. By ATMEL Corporation
