Kev piav qhia rau CC2520
CC2520 yog TI thib ob tiam ZigBee® / IEEE 802.15.4 RF transceiver rau 2.4 GHz tsis muaj ntawv tso cai ISM band.Cov nti no ua rau cov ntawv thov qib kev lag luam los ntawm kev muab cov kev xaiv ntawm lub xeev-ntawm-tus-kos duab xaiv / kev sib koom ua ke, kev sib txuas zoo heev, kev ua haujlwm txog li 125 ° C thiab kev ua haujlwm tsis tshua muaj hluav taws xob.
Tsis tas li ntawd, CC2520 muab kev txhawb nqa khoom siv dav dav rau kev tuav cov ncej, cov ntaub ntawv buffering, tawg kis, cov ntaub ntawv encryption, cov ntaub ntawv authentication, kev ntsuam xyuas meej channel, txuas cov lus qhia zoo thiab cov ntaub ntawv sijhawm sijhawm.Cov yam ntxwv no txo cov load ntawm tus tswv tswj hwm.
Nyob rau hauv ib tug raug system, CC2520 yuav siv ua ke nrog ib tug microcontroller thiab ob peb ntxiv passive Cheebtsam.
1. Leej twg yog cov neeg ua haujlwm hauv koj lub tuam tsev R & D?Koj qhov kev tsim nyog yog dab tsi?
