CC2520RHDR ka lua o ka hanauna 2.4 GHz ZigBee/IEEE 802.15.4 mea lawe uwea

ʻO ka wehewehe pōkole:

 ʻO ka CC2520 ka lua o ka hanauna o TI ZigBee®/ IEEE 802.15.4 RF transceiver no ka pūʻali ISM ʻole 2.4 GHz.Hāʻawi kēia chip i nā noi papa hana ʻenehana ma o ka hāʻawi ʻana i ke koho kiʻekiʻe o ka ʻoihana / co-existence, ka waihona pilina maikaʻi loa, ka hana a hiki i 125°C a me ka hana uila haʻahaʻa.

Eia kekahi, hāʻawi ka CC2520 i ke kākoʻo ʻenehana nui no ka mālama ʻana i ka frame, buffering data, burst transmissions, data encryption, data authentication, clear channel assessment, link quality indication and frame time information.ʻO kēia mau hiʻohiʻona e hoʻemi i ka ukana ma ka mea hoʻokele hoʻokipa.

Ma kahi ʻōnaehana maʻamau, e hoʻohana pū ʻia ka CC2520 me kahi microcontroller a me kekahi mau mea passive hou.

    - Luna Hoʻokele R & D: hoʻolālā i ka hoʻolālā R & D lōʻihi o ka hui a hopu i ke kuhikuhi o ka noiʻi a me ka hoʻomohala ʻana;Alakaʻi a mālama i ka ʻoihana r&d e hoʻokō i ka hoʻolālā r&d ʻoihana a me ka hoʻolālā R&D makahiki;E kāohi i ka holomua o ka hoʻomohala ʻana i nā huahana a hoʻoponopono i ka hoʻolālā;E hoʻonohonoho i ka hui noiʻi a me ka hoʻomohala huahana maikaʻi loa, ka loiloi a me ke aʻo ʻana i nā limahana ʻenehana pili.

    Luna R&D: hana i ka hoʻolālā R&D huahana hou a hōʻike i ka hiki o ka hoʻolālā;Mālama a mālama i ka holomua a me ka maikaʻi o ka hana r&d;E noiʻi i ka hoʻomohala huahana hou a hāʻawi i nā hopena kūpono e like me nā koi o ka mea kūʻai aku ma nā kahua like ʻole

    Nā limahana R&d: hōʻiliʻili a wehe i nā ʻikepili koʻikoʻi;polokalamu kamepiula;Ke hana nei i nā hoʻokolohua, nā hoʻokolohua a me nā loiloi;E hoʻomākaukau i nā mea hana a me nā mea hana no nā hoʻokolohua, nā hoʻokolohua a me nā loiloi;E hoʻopaʻa i ka ʻikepili ana, e helu a hoʻomākaukau i nā pakuhi;Hana i nā noiʻi helu
