Specifications of DR8000-EV

• Lead Free Status / RoHS Status: Lead free / RoHS Compliant

Interface Board
The 3G evaluation module is installed on the Interface Board for easy evaluation of the TR8000 features. Positioning the
jumper will pull the function pin “High” or “Low” and set the device feature. Refer to the pin descriptions for pin functions.
Each respective feature is marked on the Interface Board. Pins 8-15 of the evaluation module are used to set the features of
the TR8000 IC by positioning the jumpers.
Set for OOK mode
Programming Header (J4)
The programming header allows for custom firmware development for the Silicon Labs C8051F330 if desired. Contact RFM
for more information about custom firmware development.
Power-up Mode Select (J2)
J2 is used to select the operating mode of the TR8000 device only at power-up. The state of J2 when VCC is applied will determine whether
the board operates in 2G mode or 3G mode. Pin 2 (center pin) of J2 is connected to Pin 19 (CFG) of the TR8000 device and is grounded
for 2G mode and functions as the chip select line for the serial interface in 3G mode. Installing the jumper will either connect the CFG pin
of the TR8000 to GND or directly to the processor for control in 3G mode. See the table below for power-up jumper settings.
After power-up if 3G mode is selected, pin 15 (3G Sel) must be pulled ‘High’ to initiate the processor to operate in 3G mode. Failure to pull
pin 15 ‘High’ after power-up will cause the processor to remain inactive.
