11.Electrical Characteristics

For RF83/RF83C,VDDRF = VDDBB = VDD where +4.75V ≤ VDD ≤ 5.5V(RF83/RF83C); For

RF83L/RF83CL VDDRF = VDDBB = VDD where +2.75V ≤ VDD ≤ 3.3V; VSS = 0V; CAGC = 4.7µF, CTH

= 100nF; SEL0=0, SEL1 = VSS; fixed mode; For 315MHz,fREFOSC = 4.8970MHz; For

315MHz,fREFOSC = 6.7458MHz;data-rate = 1kbps (Manchester encoded). TA = 25°C, bold values

indicate –40°C ≤ TA ≤ +85°C;current flow into device pins is positive; unless noted.
