TCA9548APWR TSSOP-24 Amacandelo ombane adityanisiweyo kwisekethe yeLogic chip 1.65V-5.5V

Inkcazelo emfutshane:

TCA9548APWR 8-channel 1.65- ukuya ku-5.5-V I2C/SMBus iswitsha ngokuseta ngokutsha & ukuguqulelwa kwamandla ombane

Isixhobo se-TCA9548A sineenguqu ezisibhozo zokuguqulela kabini ezinokulawulwa ngebhasi ye-I2C.I-SCL / SDA isibini esinyukayo sabalandeli ukuya kwizibini ezisibhozo ezisezantsi, okanye iziteshi.Naliphi na itshaneli ye-SCn/SDn okanye indibaniselwano yamajelo anokuthi axutywe, agqitywe yimixholo yerejista yolawulo enokucwangciswa.Le mijelo esezantsi ingasetyenziselwa ukusombulula iingxabano zeedilesi zekhoboka ze-I2C.Umzekelo, ukuba i-sensor yedijithali efanayo iyafuneka kwisicelo, enye inzwa inokudityaniswa kwitshaneli nganye: 0-7.

Inkosi yesistim inokusetha kwakhona i-TCA9548A xa kwenzeka ixesha okanye enye into engafanelekanga ngokuqinisekisa igalelo eliphantsi kwi-RESET.Ngokufanayo, i-power-onreset ayikhethi zonke iziteshi kwaye iqalise i-I2C/SMBus statemachine.Ukuqinisekisa ukuba iRESET ibangela ukusetha ngokutsha okufanayo kunye nokuqaliswa ukuba kwenzeke ngaphandle kokunciphisa indawo.Oku kuvumela ukuchacha ukuba enye yeebhasi ze-downstreamI2C ixinga kwindawo ephantsi.

Amasango okudlula okutshintsha akhiwe ukwenzela ukuba i-pin ye-VCC ingasetyenziselwa ukunciphisa umbane ophezulu ophezulu, ogqithiswa yi-TCA9548A.Ukunciphisa awona mandla ombane aphezulu aphezulu kuvumela ukusetyenziswa kwamandla ombane ebhasi ahlukeneyo kwisibini ngasinye, ukuze i-1.8-V, 2.5-V okanye i-3.3-V iinxalenye zikwazi ukunxibelelana neenxalenye ze-5-V, ngaphandle kokhuseleko olongezelelweyo.Izichasi zokutsala zangaphandle zitsala ibhasi ukuya kwinqanaba lombane elifunekayo kwitshaneli nganye.Zonke izikhonkwane ze-I/O zinonyamezelo lwe-5-V.

Inkcazelo ye-TCA9548A

Isixhobo se-TCA9548A sineenguqu ezisibhozo zokuguqulela ezimbini ezinokulawulwa nge-I.2C ibhasi.I-SCL / SDA isibini esinyukayo sabalandeli ukuya kwizibini ezisibhozo ezisezantsi, okanye iziteshi.Naliphi na itshaneli ye-SCn/SDn okanye indibaniselwano yamajelo anokuthi axutywe, agqitywe yimixholo yerejista yolawulo enokucwangciswa.La majelo asezantsi angasetyenziselwa ukusombulula i-I2Iingxabano zentetho yamakhoboka.Umzekelo, ukuba i-sensor yedijithali efanayo iyafuneka kwisicelo, enye inzwa inokudityaniswa kwitshaneli nganye: 0-7.

Inkosi yesistim inokusetha kwakhona i-TCA9548A xa kwenzeka ixesha okanye enye into engafanelekanga ngokuqinisekisa igalelo eliphantsi kwi-RESET.Ngokufanayo, ukusetwa kwakhona kwamandla kuyeka ukukhetha onke amajelo kwaye kuqalise i-I2C/SMBus statemachine.Ukuqinisekisa ukuba iRESET ibangela ukusetha ngokutsha okufanayo kunye nokuqaliswa ukuba kwenzeke ngaphandle kokunciphisa indawo.Oku kuvumela recovery kufuneka omnye we downstreamI2Iibhasi ze-C zixinga kwimeko ephantsi.

Amasango okudlula okutshintsha akhiwe ukwenzela ukuba i-pin ye-VCC ingasetyenziselwa ukunciphisa umbane ophezulu ophezulu, ogqithiswa yi-TCA9548A.Ukunciphisa awona mandla ombane aphezulu aphezulu kuvumela ukusetyenziswa kwamandla ombane ebhasi ahlukeneyo kwisibini ngasinye, ukuze i-1.8-V, 2.5-V okanye i-3.3-V iinxalenye zikwazi ukunxibelelana neenxalenye ze-5-V, ngaphandle kokhuseleko olongezelelweyo.Izichasi zokutsala zangaphandle zitsala ibhasi ukuya kwinqanaba lombane elifunekayo kwitshaneli nganye.Zonke izikhonkwane ze-I/O zinonyamezelo lwe-5-V.
