Uhlolojikelele
I-nRF5340 iyi-SoC yokuqala engenantambo emhlabeni enamaphrosesa amabili e-Arm® Cortex®-M33. I-nRF5340 i-All-in-one SoC, okuhlanganisa isethi ephezulu yezici ezivelele kakhulu ze-nRF52® Series. Izici ezifana ne-Bluetooth® Direction Finding, i-SPI yesivinini esikhulu, i-QSPI, i-USB, izinga lokushisa elifika ku-105 °C lokusebenza, nokunye okwengeziwe, kuhlanganiswe nokusebenza okwengeziwe, inkumbulo, nokuhlanganiswa kuyilapho kunciphisa ukusetshenziswa kwamanje.
I-nRF5340 SoC isekela uhla olubanzi lwamaphrothokholi angenawaya. Isekela i-Bluetooth Low Energy futhi iyakwazi ukwenza zonke izindima ze-AoA ne-AoD ku-Bluetooth Direction Finding, ngaphezu kwalokho, i-Bluetooth Long Range kanye no-2 Mbps.
Konke-ku-munye
I-nRF5340 i-All-in-one SoC, okuhlanganisa isethi ephezulu yezici ezivelele kakhulu ze-nRF52® Series. Izici ezifana ne-USB, i-Bluetooth 5.3, izinga lokushisa elifika ku-105 °C lokusebenza, nokunye, kuhlanganiswe nokusebenza okwengeziwe, inkumbulo, kuyilapho kunciphisa ukusetshenziswa kwamanje.
Iphrosesa yohlelo lokusebenza esebenza kahle kakhulu
Iphrosesa yohlelo lokusebenza ithuthukiselwe ukusebenza futhi ingawashwa kokuthi 128 noma 64 MHz, kusetshenziswa i-voltage-frequency scaling. Ukusebenza okuphezulu kakhulu
(I-514 CoreMark ku-66 CoreMark/mA) ifinyelelwa nge-128 MHz, kuyilapho igijima ku-64 MHz inikeza inketho esebenza kahle kakhulu (257 CoreMark ku-73 CoreMark/mA).
Iphrosesa yohlelo lokusebenza ino-1 MB Flash, 512 KB RAM, iyunithi yephoyinti elintantayo (FPU), i-8 KB 2-way associative cache namandla emiyalo ye-DSP.
Iphrosesa yenethiwekhi ehleleka ngokugcwele
Iphrosesa yenethiwekhi ivalwe ku-64 MHz futhi ilungiselelwe amandla aphansi nokusebenza kahle (101 CoreMark/mA). Ine-256 KB Flash kanye ne-RAM engu-64 KB. Ikona
ihleleka ngokugcwele, ivumela umthuthukisi ukuthi akhethe ukuthi yiziphi izingxenye zekhodi ezizosebenza ngendlela esebenza kahle kakhulu, ngaphezu kwesitaki sephrothokholi engenantambo.
Ukuphepha kwezinga elilandelayo
I-nRF5340 ithatha ukuvikeleka ikuyise ezingeni elilandelayo ngokuhlanganisa i-Arm Crypto-Cell-312, i-Arm TrustZone®, kanye ne-Secure Key Storage. I-Arm TrustZone inikeza ngempumelelo ukuhlukaniswa kwehadiwe yohlelo olubanzi lwesofthiwe ethembekile ngokuhlukanisa phakathi kwezifunda ezivikelekile nezingavikelekile kumongo owodwa. Izibaluli zokuphepha ze-Flash, i-RAM, nama-peripherals zilungiselelwa kalula nge-nRF Connect SDK. I-Arm CryptoCell-312 hardware isheshisa ama-cipher aqinile namazinga wokubethela adingekayo ku-IoT eqaphela kakhulu ukuphepha.
