CC256x QFN EM User Guide 4 Measuring Current Consumption These jumpers can also be used to measure the current consumption by placing current sense resistors on R10 for VBAT_CC and R7 for VDD_1V8. Both these resistors are 0.10 Ohm, 1/4 W. VBAT_CC jumper can be used to to measure the voltage/power consumed by the CC256x including RF TX/RX while VDD_IO jumper can be used to measure voltage/power consumed by the digital I/O's. Antenna/U.

CC256x QFN EM User Guide 6 Pins 3, 9, 19, 37, 47, 63, 77, 83, 87, 95, 97, and 2, 6, 18, 22, 42, 60, 64, 92 are connected to ground. All other pins are NC (Not Connected). Clock Inputs • The slow clock can come from 2 sources, internal and external to the board. The CC256x QFN EM gives option to place the slow clock on the board itself or source it from an external source. It is connected to the SLOW_CLK_IN and can be a digital signal in the range of 0-1.8 V.
