Abstract

SE DESCRIBEN MICROCHIPS CODIFICADORES Y DESCODIFICADORES APTOS PARA SER UTILIZADOS EN DISPOSITIVOS DE CONTROL REMOTO. EL MICROCHIP CODIFICADOR CONSTA DE MEDIOS (7) PARA LLEVAR A CABO UNA FUNCION DE CODIFICACION EN UN NUMERO DE IDENTIFICACION (6) QUE SE ENCUENTRA EN DICHO MICROCHIP Y DE UNA COMBINACION DE UN NUMERO UNITARIO (CSR3, CSR2) Y UN VALOR CONTADOR PASO A PASO (CSR1, CSR0) PARA GENERAR UN VALOR DE TRANSMISION QUE SOLO PUEDE DESCODIFICARLO UNA FUNCION DESCODIFICADORA RELACIONADA QUE TIENE ACCESO AL MISMO NUMERO DE IDENTIFICACION. EL MICROCHIP DESCODIFICADOR CONSTA DE MEDIOS (13) PARA DESCODIFICAR EL VALOR DE TRANSMISION EN UN NUMERO UNITARIO DESCODIFICADO (CSR3, CSR2) Y UN VALOR CONTADOR DESCODIFICADO (CSR1 , CSR0) Y MEDIOS PARA COMPARAR EL VALOR CONTADOR DESCODIFICADO CON UN MARGEN DE VALOR CONTADOR DESCODIFICADO. LOS MICROCHIPS CODIFICADORES Y DESCODIFICADORES TIENEN TAMBIEN MEDIOS PARA SINCRONIZAR EL MICROCHIP DESCODIFICADOR CON UN MICROCHIP CODIFICADOR PARTICULAR QUE HA GENERADO UN COMANDO DE SINCRONIZACION.
