U2270B-MFPG3Y

NFC/RFID Read/Write 0.121MHz to 0.129MHz 16Pin SOIC T/R

Description

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.
