CC2400 Chipcon AS, CC2400 Datasheet - Page 13

• Manufacturer Part Number: CC2400
• Description: 2.4 GHz RF Transceiver
• Manufacturer: Chipcon AS

NOTES:
The exposed die attach pad must be connected to solid ground plane as this is the main ground connection for the
chip.
The digital inputs SCLK, SI and CSn are high-impedance inputs (no internal pull-up) and should have external pull-
ups if not driven. RX and TX should have external pull-down if not driven (to prevent the state machine from being
trigged). SO is high-impedance when CSn is high. External pull-up should be used at SO to prevent floating input at
microcontroller.
