mwachidule
NRF5340 ndiye SoC yoyamba yopanda zingwe padziko lapansi yokhala ndi mapurosesa awiri a Arm® Cortex®-M33. NRF5340 ndi SoC yonse, kuphatikiza mawonekedwe apamwamba kwambiri a nRF52® Series. Zinthu monga Bluetooth® Direction Finding, SPI yothamanga kwambiri, QSPI, USB, mpaka kutentha kwa 105 ° C, ndi zina zambiri, zimaphatikizidwa ndi ntchito zambiri, kukumbukira, ndi kugwirizanitsa pamene kuchepetsa kugwiritsira ntchito panopa.
NRF5340 SoC imathandizira ma protocol ambiri opanda zingwe. Imathandizira Bluetooth Low Energy ndipo imatha kugwira ntchito zonse za AoA ndi AoD mu Bluetooth Direction Finding, kuphatikiza, Bluetooth Long Range ndi 2 Mbps.
Zonse-m'modzi
NRF5340 ndi SoC yonse, kuphatikiza mawonekedwe apamwamba kwambiri a nRF52® Series. Zinthu monga USB, Bluetooth 5.3, mpaka 105 °C kutentha kwa ntchito, ndi zina, zimaphatikizidwa ndi ntchito zambiri, kukumbukira, ndikuchepetsa kugwiritsa ntchito panopa.
Purosesa yogwiritsira ntchito kwambiri
Purosesa yogwiritsira ntchito imakonzedwa kuti igwire ntchito ndipo imatha kuyatsidwa pa 128 kapena 64 MHz, pogwiritsa ntchito ma voltage-frequency scaling. Kuchita kwapamwamba kwambiri
(514 CoreMark pa 66 CoreMark/mA) imapezeka ndi 128 MHz, pamene kuthamanga pa 64 MHz kumapereka njira yowonjezera (257 CoreMark pa 73 CoreMark / mA).
Purosesa yogwiritsira ntchito ili ndi 1 MB Flash, 512 KB RAM, unit floating-point (FPU), 8 KB 2-way associative cache ndi luso la malangizo a DSP.
Pulogalamu yapaintaneti yokhazikika bwino
Purosesa ya netiweki imakhala ndi wotchi ya 64 MHz ndipo imakongoletsedwa ndi mphamvu zochepa komanso kuchita bwino (101 CoreMark/mA). Ili ndi 256 KB Flash ndi 64 KB RAM. Zili choncho
zokonzedwa bwino, zomwe zimathandiza wopanga mapulogalamu kuti asankhe zigawo ziti za kachidindo zomwe zikuyenera kuyendetsa bwino kwambiri, kuphatikiza pa stack ya protocol yopanda zingwe.
Chitetezo chotsatira
NRF5340 imatenga chitetezo ku mlingo wotsatira mwa kuphatikiza Arm Crypto-Cell-312, Arm TrustZone®, ndi Secure Key Storage. Arm TrustZone imapereka njira zodzipatula zamakompyuta pamapulogalamu odalirika polekanitsa madera otetezeka komanso osatetezedwa pachinthu chimodzi. Makhalidwe achitetezo a Flash, RAM, ndi zotumphukira zimakonzedwa mosavuta kudzera mu nRF Connect SDK. Zida za Arm CryptoCell-312 zimafulumizitsa ma ciphers amphamvu ndi mfundo zachinsinsi zomwe zimafunikira mu IoT yosamala kwambiri zachitetezo.
