Kev piav qhia rau TCA9555
Qhov no 16-ntsis I / O expander rau ob-kab tsheb npav bidirectional (I2C) yog tsim los rau 1.65-V rau 5.5-V VCCoperation.Nws muab cov hom phiaj dav dav I/O nthuav dav rau feem ntau cov tsev neeg microcontroller ntawm I2C interface.
Lub TCA9555 muaj ob lub 8-ntsis Configuration (cov tswv yim los yog cov zis xaiv), Input Port, Output Port, thiab Polarity Inversion (active siab lossis nquag ua haujlwm qis) sau npe.Thaum lub hwj chim qhib, I/Os yog configured li inputs.Tus tswv system tuaj yeem pab I/Os raws li kev nkag lossis tawm los ntawm kev sau ntawv mus rau I / O teeb tsa cov khoom.Cov ntaub ntawv rau txhua qhov kev tawm tswv yim lossis cov khoom tso tawm yog khaws cia rau hauv cov khoom nkag lossis cov ntawv tso tawm.Lub polarity ntawm Input Port register tuaj yeem hloov nrog lub npe Polarity Inversion.
Lub TCA9555 zoo ib yam rau TCA9535, tshwj tsis yog rau kev suav nrog lub internalI / O rub-up resistor, uas rub lub I / O mus rau lub neej ntawd siab thaum configured raws li ib tug input andundriven.
Peb tus pins kho vajtse (A0, A1, thiab A2) yog siv los ua qhov chaw nyob I2C, uas tso cai rau yim TCA9555 cov khoom siv los sib faib tib I2C tsheb npav lossis SMBus.Qhov chaw nyob ruaj khov I2C ntawm TCA9555 yog tib yam li PCF8575, PCF8575C, thiab PCF8574, tso cai rau yim ntawm cov cuab yeej no hauv ib qho kev sib koom ua ke los qhia tib lub tsheb npav I2C lossis SMBus.
