Ukuqhathaniswa kwabakhiqizi
1. CC2640R2F: Kuyi-7mm*7mm volumetric patch uhlobo lwe-BLE4.2/5.0 ye-Bluetooth chip eyethulwe yi-Texas Instruments (TI), enomongo we-ARM M3 owakhelwe ngaphakathi. Njengenguqulo ethuthukisiwe ye-CC2640, i-CC2640R2F ithuthukiswe ngokugcwele mayelana nezinqubo ezisekelayo nenkumbulo.
2. I-NRF52832: Kuyi-chip ye-Bluetooth ye-BLE5.0 eyethulwe yi-Nordic Semiconductor (Nordic), enomongo owakhelwe ngaphakathi we-ARM M4F. I-NRF52832 inguqulo ethuthukisiwe ye-NRF51822. Umongo othuthukisiwe unamandla ekhompuyutha anamandla kanye nobuchwepheshe bekhompuyutha bephoyinti elintantayo.
Isilinganiso se-chipset
1. I-CC2640R2F: Njengoba kuboniswe emfanekisweni ongezansi, i-CC2640R2F iqukethe amakhora omzimba amathathu(CPU). I-CPU ngayinye ingasetshenziswa ngokuzimela noma kwabelwane nge-RAM/ROM. I-CPU ngayinye yenza imisebenzi yayo futhi isebenza ngokubambisana, ithola ukulingana phakathi kokusebenza nokusetshenziswa kwamandla ngezinga elikhulu kakhulu. Imisebenzi eyinhloko yesilawuli senzwa isilawuli se-peripheral, isampula ye-ADC, ukuxhumana kwe-SPI, njll. Uma isistimu i-CPU dormancy, isilawuli Senzwa singasebenza ngokuzimela. Lo mklamo wehlisa kakhulu imvamisa yokuvuka ye-CPU futhi yehlisa ukusetshenziswa kwamandla.
2. I-NRF52832: Njengoba kuboniswe emfanekisweni ongezansi, i-nRF52832 iwumgogodla owodwa we-SoC, okusho ukuthi ngemva kokuqala isitaki sephrothokholi ye-BLE, isitaki sephrothokholi sihamba phambili kakhulu. Okubalulekile kohlelo lwesicelo kuzoba ngaphansi kwalokho kwesitaki sephrothokholi, futhi ukusebenza kungase kuthinteke ezinhlelweni ezinezidingo zesikhathi sangempela eziphezulu njengokulawula kwezimoto. Emakethe yedivayisi egqokekayo, amandla ekhompuyutha aqinile ayadingeka, kodwa kwezinye izinhlelo zokusebenza, njengokuqoqwa kwezinzwa nokucubungula okulula nakho kuyizinketho ezinhle.

I-CC2640R2F kanye ne-NRF52832 Ukuqhathaniswa kwezici
1. I-CC2640R2F isekela i-BLE4.2 ne-BLE5.0, ine-crystal oscillator yewashi eyakhelwe ngaphakathi engu-32.768kHz, isekela ibhendi yefrikhwensi yamahhala ye-ISM2.4GHz, esebenza kahle kakhulu futhi enamandla aphansi i-Cortex-M3. kanye nama-Cortex-M0 ama-dual-core processors. Izinsiza eziningi, 128KB FLASH, 28KB RAM, ukusekela ukunikezwa kwamandla okungu-2.0～3.6V, ukunikezwa kwamandla okukhulu kuno-3.3V kungaqinisekisa ukusebenza okungcono kakhulu.
2. I-NRF52832 single chip, 2.4GHz multi-protocol SoC evumelana nezimo kakhulu, isekela i-BLE5.0, ibhendi yefrikhwensi engu-2.4GHz, iphrosesa engu-32-bit ARM Cortex-M4F, i-voltage yokunikezela engu-3.3V, ububanzi 1.8V ~ 3.6V, 512kB flash memory + 64kB RAM , isixhumanisi somoya siyahambisana nochungechunge lwe-nRF24L kanye ne-nRF24AP.
Njengamanje, i-Feasycom inemojula ye-Bluetooth ye-FSC-BT630 esebenzisa i-chipset ye-NRF52832, futhi i-FSC-BT616 isebenzisa i-chipset ye-CC2640R2F.
