1. Description
The U9280M-H IC is a multi-chip module for remote control and contactless ID sys-
tems. It consists of the ATAR092 microcontroller and U3280M transponder interface
circuit with EEPROM. A coil connected to the transponder interface serves as a wire-
less bi-directional communication interface as well as a power supply for the
microcontroller and the interface. As a transponder, the device is supplied by a mag-
netic RF field applied at the coil. For IR- or RF-transmitter applications, it can be
supplied by a battery. The microcontroller supports, with its built-in timers, a wide
range of IR- and RF-transmission modes such as burst-modulation modes, PWM-,
NRZ-, Manchester- and Bi-phase coding.
