In addition, the chip offers various packaging for flexible combination of programmable address/data so as to meet various applications. Its programmable address/data is transmitted together with the anti-code bits via RF or infrared transmission medium upon receipt of a trigger signal. The HT6P20X is a CMOS LSI encoder designed for remote control system applications. It encodes 24 bits of information and then serially transmits it via the DOUT pin upon receipt of transmission enable (DATA pins: D0~D7) signals. The combination of address and data bits of the HT6P20X is designed using one time pro- Block Diagram O S C 1 O S C 2 V P P S IO O s c illa to r A d d re s s C o u n te r P r o g r a m m in g C ir c u it M ix e r & D r iv e r C o n tr o l U n it D a ta L a tc h P G M D 0 D O U T D 7 Note: Address/Data numbers are available in various combinations, refer to the functional description.
