NRF52820-QDAA-R RF System pa Chip - SoC nRF52820-QDAA QFN 40L 5×5

NRF52820 System-on-Chip (SoC) ndi 6th yowonjezera ku makampani otsogolera nRF52® Series. Imawonjezera kusonkhanitsa kwakutali kwa ma SoC opanda zingwe okhala ndi njira yotsikirapo yokhala ndi USB yomangidwa komanso wailesi yowoneka bwino ya multipro-tocol. Mndandanda wa nRF52 ndiwowonadi nsanja yabwino yokhazikitsira malonda. Mapangidwe a hardware ndi mapulogalamu odziwika bwino amapangitsa kuti mapulogalamu azitha kusuntha bwino, kuonjezera kusinthika kwa mapulogalamu ndikuchepetsa nthawi yogulitsa malonda ndi chitukuko.

NRF52820 imakhala ndi purosesa ya Arm® Cortex®-M4, yomwe imakhala ndi 64 MHz. Ili ndi 256 KB Flash ndi 32 KB RAM, komanso mawonekedwe osiyanasiyana a analogi ndi digito monga chofananira cha analogi, SPI, UART, TWI, QDEC, ndipo chomaliza, USB. Itha kuperekedwa ndi ma voliyumu kuchokera ku 1.7 mpaka 5.5 V yomwe imathandizira kuyatsa chipangizocho kuchokera kumagwero monga mabatire otha kuchajwanso kapena kudzera pa USB.

NRF52820 imathandizira Bluetooth 5.3, kuwonjezera pa Direction Finding, 2 Mbps yapamwamba kwambiri ndi mawonekedwe a Long Range. Ithanso kugwiritsa ntchito ma protocol a Blue-tooth, Thread ndi Zigbee mesh.

Kwa makina ogwiritsira ntchito mawonekedwe a anthu (HID) mphamvu zomangidwira za USB ndi +8 dBm TX zimapangitsa nRF52820 kukhala njira yabwino kwambiri ya chip-chip imodzi, pomwe ntchito zolondolera katundu zimatha kukulitsa luso lake la Bluetooth Direction Finding. Kutentha kotalikirapo kwa -40 mpaka +105 °C kumapangitsa kuti ikhale yoyenera kuwunikira akatswiri.

USB yomangidwira, wailesi ya multiprotocol yowonetsedwa bwino ndi +8 dBm mphamvu yotulutsa imapangitsa kukhala purosesa yabwino kwambiri ya netiweki kuti iphatikizidwe ndi pulogalamu ya MCU m'zipata ndi ntchito zina zanzeru zapanyumba, zamalonda ndi zamafakitale zomwe zimafuna kulumikizidwa kopanda zingwe.
