ʻO ka AM1705 kahi microprocessor ARM haʻahaʻa e pili ana i kahi ARM926EJ-S.Hāʻawi ka mea hana i nā mea hana mea hana kumu (OEM) a me nā mea hana hoʻolālā kumu (ODMs) e lawe koke i nā mea kūʻai aku me nā ʻōnaehana hana ikaika, nā mea hoʻohana waiwai nui, a me ka hana kiʻekiʻe o ka mīkini hana ma o ka hiki ke maʻalahi o ka hoʻohui piha ʻana i ka ʻōnaehana hui.ʻO ka ARM926EJ-S he 32-bit RISC core processor e hana ana i nā ʻōlelo kuhikuhi 32-bit a i ʻole 16-bit a me nā kaʻina 32-, 16-, a i ʻole 8-bit ʻikepili.Hoʻohana ke kumu i ka pipelining i hiki i nā ʻāpana āpau o ka processor a me ka ʻōnaehana hoʻomanaʻo ke hana mau.Loaʻa i ka ARM core kahi coprocessor 15 (CP15), module pale, a me ka ʻikepili a me nā ʻāpana hoʻomanaʻo hoʻomanaʻo papahana (MMUs) me nā pale nānā ʻaoʻao.He 16KB kaawale o ke a'o a me 16-KB ko ka ARM core.ʻO nā poloka hoʻomanaʻo ʻelua he 4-ala hui me ka virtual index virtual tag (VIVT).Loaʻa i ka ARM core ka 8KB o RAM (Vector Table) a me 64KB o ROM.Aia i loko o ka pūʻali peripheral: kahi 10/100 Mbps Ethernet MAC (EMAC) me kahi module hoʻokomo / hoʻopuka (MDIO);ʻelua mau kikowaena I 2C Bus;ʻekolu mau ʻauwaʻa leo leo multichannel (McASPs) me nā serializers a me nā pale FIFO;ʻelua 64-bit mea hoʻohana maʻamau i kēlā me kēia mea hoʻonohonoho (hoʻokahi configurable e like me ka ʻīlio kiaʻi);a hiki i 8 mau panakō o 16 mau pine o ka mea hoʻokomo/puka kumu nui (GPIO) me nā ʻano hana hoʻoneʻe papahana/hana hanana, i hoʻohui ʻia me nā peripheral ʻē aʻe;ʻekolu mau pilina UART (hoʻokahi me RTS a me CTS);ʻekolu mau mea hoʻololi i hoʻonui ʻia i ka pulse width modulator (eHRPWM);ʻekolu 32-bit enhanced capture (eCAP) module peripherals i hiki ke hoʻonohonoho ʻia ma ke ʻano he 3 hoʻokomo hopu a i ʻole 3 mau mea hoʻopukapuka ākea pulse width modulator (APWM);ʻelua 32-bit enhanced quadrature encoded pulse (eQEP) peripherals;a me 2 mau mea hoʻomanaʻo hoʻomanaʻo waho: kahi asynchronous a me SDRAM hoʻomanaʻo hoʻomanaʻo waho (EMIFA) no ka hoʻomanaʻo lohi a i ʻole peripheral, a me kahi kiʻekiʻe o ka wikiwiki hoʻomanaʻo hoʻomanaʻo (EMIFB) no SDRAM.Hāʻawi ka Ethernet Media Access Controller (EMAC) i kahi pilina kūpono ma waena o ka mea hana a me ka pūnaewele.Kākoʻo ka EMAC iā 10Base-T a me 100Base-TX, a i ʻole 10 Mbps a me 100 Mbps ma kēlā me kēia hapalua no ke ʻano duplex piha.Eia hou, loaʻa kahi interface MDIO no ka hoʻonohonoho PHY.
