型號(hào)： U9280M-H

類別： 集成電路

描述： Description The U9280M-H IC is a multi-chip module for remote control and contactless ID systems. 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 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.
