6. Power Supply Section The power supply section contains two voltage regulators One is an external 3 3 V regulator for use by the microcontroller and the I O pins of the CC2420 The second is an internal regulator of CC2420 used to generate the 1 8 V supply applied for powering of the CC2420 core A diode prevents permanent damage if wrong polarity is applied to the board There are two power connectors a 2 5mm DC jack type connector allows you to connect an unregulated battery eliminator easily the positive supply is on the center pin and a connector for a 9V battery on the bottoms side of the PCB We recommend that 3 or 4 AA or AAA alkaline cells are used to power the CC2420DB if a suitable battery pack is used RS 232 Interface A serial port is included on the CC2420DB This port can be used with the Figure 8 Wireless Z Trace The port includes support for RTS CTS type hardware flow control handshaking This port is per default always enabled by a jumper See the jumper settings for demonstration board control Microcontroller and User Interface The microcontroller used is an AVR ATmega128L from Atmel This controller has 128 kB of Flash program memory 4 kB of SRAM data memory and 4 kB of non volatile EEPROM data memory The controller is interfaced to the CC2420 via its built in SPI interface as well as few general purpose I O pins The MCU is also connected to four LEDs a joystick and an extra button for user interface purposes
7. The different examples use these peripherals differently An analogue temperature sensor a potentiometer and 32 kB of external RAM are also included An ISP and a JTAG ICE connector are provided for programming the AVR without using the serial port In this case an Atmel AVR JTAG or ISP programmer should be connected to their respective connectors All of the I O pins are connected to footprints for 2 x 10 pin row connectors P3 and P4 These connectors are compatible with Agilent logic analyzer probes and can be used either for testing or for prototyping For instance it is possible to add a daughter board containing additional circuitry using these connectors Connector P3 pinout Pin Signal name in Pin usage AVR pin number schematic 1 Not Connected Not Applicable N A N A NC 2 Unregulated supply voltage N A Insert R101 to connect 3 FORCE_ON RS 232 Force On N A Chipcon AS SmartRF CC2420 ZigBee Development Kit User Manual rev 1 0 2004 09 13 Page 10 28 4 4 Yellow LED RS 232 Force 06 PE4 control 5 PE2 Joystick centre push button 04 PE2 6 PEO ISP MOSI Joystick up 02 PEO External 32 kHz crystal 18 PG3 General purpose PE1 ISP MISO Joystick right 03 PE1 9 PG4 External 32 kHz crystal 19 PG4 General purpose 10 PE5 Push button S2 07 PE5 11 PE3 Red LED 05 PE3
