Overview
Ko te nRF5340 te SoC ahokore tuatahi o te ao me nga pūtukatuka Arm® Cortex®-M33 e rua. Ko te nRF5340 he SoC katoa-i-kotahi, tae atu ki te huinga huinga o nga ahuatanga tino rongonui o te raupapa nRF52®. Ko nga ahuatanga penei i te Rapu Aratohu Bluetooth®, SPI tere-tere, QSPI, USB, tae atu ki te 105 °C te pāmahana whakahaere, me etahi atu, ka honoa me te nui ake o te mahi, te mahara, me te whakauru i te wa e whakaitihia ana te kohi o naianei.
E tautoko ana te nRF5340 SoC i te whānuitanga o nga kawa ahokore. E tautoko ana i te Nihokikorangi Low Energy me te kaha ki nga mahi AoA me te AoD katoa i roto i te Rapu Aronga Nihokikorangi, i tua atu, Nihokikorangi Awhe Roa me te 2 Mbps.
Katoa-i-kotahi
Ko te nRF5340 he SoC katoa-i-kotahi, tae atu ki te huinga huinga o nga ahuatanga tino rongonui o te raupapa nRF52®. Ko nga ahuatanga penei i te USB, Nihokikorangi 5.3, tae atu ki te 105 °C te pāmahana whakahaere, me etahi atu, ka honoa me te nui ake o te mahi, te mahara, me te whakaiti i te kohi o naianei.
Tukatuka tono mahi teitei
Kua arotauhia te tukatuka tono mo te mahi, ka taea te karaka i te 128, 64 MHz ranei, ma te whakamahi i te tauine ngaohiko-auau. Ko te mahi teitei
(514 CoreMark i te 66 CoreMark/mA) kua tutuki ki te 128 MHz, i te wa e rere ana i te 64 MHz he pai ake te waahanga (257 CoreMark i te 73 CoreMark/mA).
Ko te tukatuka tono he 1 MB Flash, 512 KB RAM, he waeine-iti (FPU), he 8 KB 2-ara keteroki hono me te kaha ako DSP.
Pūtukatuka whatunga tino-hōtaka
Ko te tukatuka whatunga kua karaka ki te 64 MHz me te arotau mo te iti o te kaha me te kaha (101 CoreMark/mA). He 256 KB Flash me te 64 KB RAM. Ko te
ka taea te hotaka, ka taea e te kaiwhakawhanake te kowhiri kohea nga waahanga o te waehere hei whakahaere me te tino pai, hei taapiri atu ki te kawa kawa ahokore.
Haumarutanga taumata muri
Ka mau te nRF5340 i te haumarutanga ki te taumata e whai ake nei ma te whakauru i te Arm Crypto-Cell-312, Arm TrustZone®, me te Rokiroki Kī Haumaru. He pai te whakarato a Arm TrustZone i te wehenga taputapu-whanui mo te rorohiko pono ma te wehe i waenga i nga rohe haumaru me te kore-haumaru i runga i te kaupapa kotahi. Ko nga huanga haumarutanga o te Flash, te RAM, me nga peripheral he ngawari te whirihora ma te nRF Connect SDK. Ko te taputapu Arm CryptoCell-312 e whakatere ana i nga ciphers kaha me nga paerewa whakamunatanga e hiahiatia ana i roto i te IoT tino mohio ki te haumaru.
