Kufotokozera

AM1705 ndi ARM microprocessor yamphamvu yotsika yotengera ARM926EJ-S.Chipangizochi chimathandizira opanga zida zoyambira (OEMs) ndi opanga mapangidwe oyambira (ODM) kuti abweretse mwachangu zida zamsika zokhala ndi machitidwe olimba ogwiritsira ntchito, mawonekedwe ogwiritsira ntchito olemera, komanso magwiridwe antchito apamwamba kudzera pakusinthasintha kwakukulu kwa njira yophatikizira yosakanikirana, yosakanikirana.ARM926EJ-S ndi purosesa ya 32-bit RISC yomwe imapanga malangizo a 32-bit kapena 16-bit ndi ndondomeko 32-, 16-, kapena 8-bit data.Pakatikati imagwiritsa ntchito mapaipi kuti magawo onse a purosesa ndi kukumbukira kukumbukira azigwira ntchito mosalekeza.Pakatikati ya ARM ili ndi coprocessor 15 (CP15), gawo lachitetezo, ndi magawo owongolera ma data ndi mapulogalamu (MMUs) okhala ndi ma buffer owonera patebulo.Pakati pa ARM ili ndi 16KB yosiyana ya malangizo ndi 16-KB data cache.Ma block block onse ndi 4-way associative ndi virtual index virtual tag (VIVT).Pakatikati pa ARM ilinso ndi 8KB ya RAM (Vector Table) ndi 64KB ya ROM.Kuyika kwapang'onopang'ono kumaphatikizapo: 10/100 Mbps Ethernet MAC (EMAC) yokhala ndi gawo lothandizira deta / zotuluka (MDIO);awiri I 2C Bus interfaces;madoko atatu amtundu wanyimbo (McASPs) okhala ndi ma serializers ndi mabafa a FIFO;zowonera nthawi ziwiri za 64-bit iliyonse yosinthika (imodzi yosinthika ngati ulonda);mpaka 8 mabanki a 16 mapini a general-purpose input/output (GPIO) okhala ndi njira zosokoneza / zopangira zochitika, zochulukitsa ndi zotumphukira zina;mawonekedwe atatu a UART (imodzi yokhala ndi RTS ndi CTS);zotumphukira zitatu za high-resolution pulse wide modulator (eHRPWM);ma module atatu a 32-bit enhanced Capture (eCAP) omwe amatha kusinthidwa ngati zolowetsa 3 kapena zotulutsa 3 zothandizira pulse wide modulator (APWM);zotumphukira ziwiri za 32-bit quadrature encoded pulse (eQEP);ndi 2 kunja kukumbukira mawonekedwe: asynchronous ndi SDRAM kunja kukumbukira mawonekedwe (EMIFA) kwa kukumbukira pang'onopang'ono kapena zotumphukira, ndi mawonekedwe othamanga kwambiri kukumbukira (EMIFB) kwa SDRAM.Ethernet Media Access Controller (EMAC) imapereka mawonekedwe abwino pakati pa chipangizocho ndi netiweki.EMAC imathandizira 10Base-T ndi 100Base-TX, kapena 10 Mbps ndi 100 Mbps munjira ziwiri kapena ziwiri.Kuphatikiza apo, mawonekedwe a MDIO amapezeka pakusintha kwa PHY.
