1. Description

The U3280M is a transponder interface for use in contactless ID systems, remote con-

trol systems, tag and sensor applications. It supplies the microcontroller with power

from an RF field via an LC-resonant circuit and it enables contactless bi-directional

data communication via this RF field. It includes power management that handles

switching between the magnetic field and a battery power supply. To store permanent

data like an identifier code and configuration data, the U3280M includes a 512-bit

EEPROM with a serial interface.
