Electrical Characteristics(4)
VDDRF = VDDBB = VDD where +4.75V ≤ VDD ≤ 5.5V, VSS = 0V; CAGC = 4.7µF, CTH = 0.022µF; SEL0 = VDD; SEL1 = VSS; fixed mode
(SWEN = VSS); fREFOSC = 9.794MHz (equivalent to fRF = 315MHz); datarate = 600bps (Manchester encoded). TA = 25°C, bold
values indicate –40°C ≤ TA ≤ +85°C; current flow into device pins is positive, unless noted.
