I-NRF52820-QDAA-R RF Uhlelo ku-Chip – SoC nRF52820-QDAA QFN 40L 5×5

I-nRF52820 System-on-Chip (SoC) iyisengezo sesi-6 kuchungechunge lwe-nRF52® oluhamba phambili embonini. Yengeza iqoqo eselivele libanzi lama-SoCs angenantambo ngenketho esezingeni eliphansi ene-USB eyakhelwe ngaphakathi kanye nomsakazo we-multipro-tocol ofakwe ngokugcwele. I-nRF52 Series iyinkundla ekahle ngempela yokusekela iphothifoliyo yomkhiqizo. Izingxenyekazi zekhompuyutha ezivamile nezakhiwo zesofthiwe ziphumela ekuphathekeni kwesofthiwe okuhle kakhulu, okwandisa ukusebenziseka kabusha kwesofthiwe kanye nokwehlisa isikhathi sokuya emakethe kanye nezindleko zokuthuthuka.

I-nRF52820 ifaka iphrosesa ye-Arm® Cortex®-M4, enewashi elingu-64 MHz. Ine-256 KB Flash kanye ne-RAM engu-32 KB, kanye nohlu lwe-analog ne-digital inter-face njengesiqhathaniso se-analog, i-SPI, i-UART, i-TWI, i-QDEC, futhi okokugcina, i-USB. Ingahlinzekwa nge-voltage esuka ku-1.7 kuya ku-5.5 V enika amandla amandla edivayisi kusuka emithonjeni efana namabhethri aphinde ashajwe noma nge-USB.

I-nRF52820 isekela i-Bluetooth 5.3, ngaphezu kwe-Direction Finding, i-high-throughput 2 Mbps nezici ze-Long Range. Futhi ikwazi ukwenza i-Blue-tooth mesh, i-Thread ne-Zigbee mesh protocol.

Kuzinhlelo zokusebenza zedivayisi yokusebenzelana kwabantu (HID) amandla akhelwe ngaphakathi e-USB kanye ne-+8 dBm TX enza i-nRF52820 ibe inketho enkulu ye-single-chip, kuyilapho izinhlelo zokusebenza zokulandelela impahla zingasebenzisa amandla ayo Okuthola Ukuqondisa Kwe-Bluetooth. Izinga lokushisa elisalinde isikhathi eside lika -40 kuya ku-+105 °C lilenza lifanelekele ukukhanyisa okuqeqeshiwe.

I-USB eyakhelwe ngaphakathi, irediyo ye-multiprotocol egcwele izici eziningi namandla okukhiphayo angu-+8 dBm iyenza iphrosesa yenethiwekhi efanelekile ukuthi imataniswe ne-MCU yohlelo lokusebenza emasangweni nezinye izinhlelo zokusebenza ezihlakaniphile zasekhaya, ezentengiso nezezimboni ezidinga ukuxhumana okungenantambo okuthuthukile.
