Electrical Characteristics(4)

VDDRF = VDDBB = VDD where +4.75V ≤ VDD ≤ 5.5V, VSS = 0V; CAGC = 4.7µF, CTH = 100nF; SEL0 = SEL1 = VSS; fixed mode

(SWEN = VSS); fREFOSC = 4.8970MHz (equivalent to fRF = 315MHz); 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.
