U9280M-H

Note: Stresses greater than those listed under absolute maximum ratings may cause permanent damage to the device. This is a stress rating only and functional operation of the device at any condition above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating condition for an extended period may affect device reliability. All inputs and outputs are protected against high electrostatic voltages or electric fields. However, precautions to minimize the build-up of electrostatic charges during handling are recommended. Reliability of operation is enhanced if unused inputs are connected to an appropriate logic voltage level (e.g., V_DD).

The U9280M-H IC is a multi-chip module for remote control and contactless ID systems.U9280M-H consists of the ATAR092 microcontroller and U3280M transponder interface circuit with EEPROM. A coil connected to the transponder interface serves as a wireless bi-directional communication interface as well as a power supply for the microcontroller and the interface. As a transponder, the U9280M-H is supplied by a magnetic 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.
