Bayani na TCA9555
Wannan mai faɗaɗa I/O mai 16-bit don bas ɗin mai layi biyu (I2C) an tsara shi don 1.65-V zuwa 5.5-V VCCoperation.Yana ba da faɗaɗa I/O mai nisa gabaɗaya don yawancin iyalai masu sarrafa microcontroller ta hanyar dubawar I2C.
TCA9555 ta ƙunshi Kanfigareshan 8-bit guda biyu ( zaɓin shigarwa ko fitarwa), Port Input Port, Port Output, da Polarity Inversion (aiki mai girma ko ƙaramin aiki).Lokacin kunnawa, ana saita I/Os azaman abubuwan shiga.Mai kula da tsarin zai iya ba da damar I/Os a matsayin ko dai abubuwan da ake shigar da su ta hanyar rubutawa zuwa raƙuman sanyi na I/O.Ana adana bayanan kowane shigarwa ko fitarwa a cikin rajistar shigarwar ko fitarwa daidai.Za a iya juyar da polarity na rajistar Port Port tare da rajistar Juyawa ta Polarity.
TCA9555 yayi kama da TCA9535, ban da haɗawa da resistor na ciki/O mai cirewa, wanda ke jan I/O zuwa babban tsoho lokacin da aka saita azaman shigarwa kuma ba a gama ba.
