TCA9548APWR TSSOP-24 Zvigadzirwa zvemagetsi zvakabatanidzwa dunhu Logic chip 1.65V-5.5V
Zvimiro zveTCA9548A
●1-ku-8 Bidirectional kuturikira masiwichi
●I2C Bhazi uye SMBus inoenderana
●Active-low reset input
● Mapini matatu ekero, anobvumira anosvika masere eTCA9548A zvishandiso paI2C bhazi
●Kusarudzwa kwechiteshi kuburikidza neI2C Bhazi, mune chero musanganiswa
●Simba nemachaneli ese akasasarudzwa
●Low RONswitches
● Inobvumira kushandura kwevoltage-level pakati pemabhazi 1.8-V, 2.5-V, 3.3-V, uye 5-V
● Hapana glitch pakukwira kwemagetsi
● Inotsigira kuiswa kunopisa
●Low standby current
●Kushanda simba-supply voltage range ye
●1.65 V kusvika ku5.5 V
●5-V Inobvumira kupinza

Tsanangudzo yeTCA9548A
Iyo TCA9548A mudziyo ine sere bidirectional kushandura switch inogona kudzorwa kuburikidza neI.2C bhazi.Iyo SCL/SDA inokwira pair mafeni kunze kusvika masere akadzika rwizi paviri, kana chiteshi.Chero chero munhu SCn/SDn chiteshi kana musanganiswa wematanho anogona kuvharwa, akatemerwa nezviri mukati meiyo programmable control rejista.Aya akadzika nzira anogona kushandiswa kugadzirisa I2C muranda address makakatanwa.Semuyenzaniso, kana masere akafanana edhijitari tembiricha ma sensors achidikanwa mukushandisa, sensor imwe inogona kubatana pachiteshi chega chega: 0-7.
Iyo sisitimu master inogona kuseta zvakare TCA9548A muchiitiko chenguva-kunze kana kumwe kusashanda zvakanaka nekusimbisa yakaderera mune RESET yekuisa.Saizvozvo, iyo simba-onreset inobvisa ese machani uye inotanga iyo I2C/SMBus statemachine.Asserting RESET inokonzeresa kuseta zvakare uye kutanga kuti zviitike pasina kudzikisira chikamu.Izvi zvinobvumira kupora kana imwe yezasi I2C mabhazi anonamira munzvimbo yakaderera.
Magedhi ekupfuura ekuchinja anovakwa kuitira kuti pini yeVCC igone kushandiswa kudzikamisa yakakwira voltage, iyo inopfuudzwa neTCA9548A.Kudzikamisa iyo yakanyanya kukwirisa voltage inobvumira kushandiswa kweakasiyana mabhazi voltages papeya yega yega, kuitira kuti 1.8-V, 2.5-V kana 3.3-V zvikamu zvinokwanisa kutaurirana ne5-V zvikamu, pasina kumwe kudzivirirwa.External pullup resistors dhonza bhazi kusvika painodiwa voltage level kune yega yega chiteshi.Mapini eI/O ese ane 5-V anoshivirira.
1. Ndivanaani vashandi mudhipatimendi rako reR & D?Ndezvipi zvidzidzo zvako?
-R & D Mutungamiriri: gadzira chirongwa chekambani chenguva refu R & D uye ubate gwara rekutsvaga nekusimudzira;Tungamira uye tarisa r&d dhipatimendi kuti iite kambani r&d zano uye yegore R&D chirongwa;Dzora kufambira mberi kwekugadzirwa kwechigadzirwa uye gadzirisa chirongwa;Gadzira yakanakisa chigadzirwa chekutsvagisa uye timu yekusimudzira, yekuongorora uye yekudzidziswa ine chekuita nehunyanzvi vashandi.
R & D Maneja: gadzira chigadzirwa chitsva R & D kuronga uye kuratidza kugona kwechirongwa;Tarisa uye gadzirisa kufambira mberi uye kunaka kwer&d basa;Tsvagurudza kugadzirwa kwechigadzirwa chitsva uye kurudzira mhinduro dzinoshanda zvinoenderana nezvinodiwa nevatengi munzvimbo dzakasiyana
Vashandi veR&d: unganidza uye gadzirisa data rakakosha;Computer programming;Kuita zviedzo, bvunzo uye ongororo;Gadzirira zvinhu uye zvishandiso zvekuyedza, bvunzo uye ongororo;Rekodha data yekuyera, ita kuverenga uye gadzira machati;Ita ongororo dzenhamba
2. Ndeipi yako chigadzirwa tsvakurudzo uye budiriro pfungwa?
-Kufunga kwechigadzirwa uye sarudzo yechigadzirwa pfungwa uye yekuongorora tsanangudzo yechigadzirwa uye dhizaini dhizaini uye kusimudzira chigadzirwa kuyedzwa uye kusimbiswa kwekutanga kumusika.
