Introduction
The CC2420 is a single-chip, IEEE 802.15.4 compliant and ZigBee™ ready RF transceiver. It
provides a highly integrated, flexible low-cost solution for applications using the world wide
unlicensed 2.4 GHz frequency band. The CC2420 ZigBee DK Development Kit is a natural
supplement to the already established Chipcon CC2420 kits, i.e. the CC2420DK
Development Kit and the CC2420DBK Demonstration Board Kit. The hardware is
representative of an actual application, and is well suited as a prototyping, evaluation and
demonstration platform targeting various ZigBee applications. With this kit a ZigBee Logical
device type mapped to the IEEE 802.15.4 Full Function and Reduced Function Devices (FFD
and RFD) using the CC2420 can be demonstrated. An FFD can take the role of a ZigBee
Coordinator, Router, or End Device depending on the ZigBee logical device type
configuration. An RFD can act as ZigBee End Device and cannot serve as a ZigBee
Coordinator or ZigBee Router.
The CC2420 ZigBee DK has the capability to demonstrate ZigBee low power capabilities.
The CC2420 ZigBee DK is bundled with the Figure 8 Wireless ZigBee stack for evaluation,
demonstration, prototyping and developing purposes of the Z-Stack features. The hardware
platform is based on the CC2420DB Demonstration Board. The hardware contains an
integrated PCB antenna, the IEEE 802.15.4 compliant RF transceiver CC2420 with
necessary support components, an Atmel Atmega128L AVR microcontroller, 32 kB external
RAM, and, as well as a joystick, buttons and LED’s that can be used to demonstrate the
current ZigBee Home Lightning Profile. Please note that CC2420DB includes this memory
because it can be used for debugging purposes, to buffer and store data if desired. The 32kB
external RAM size is not a requirement nor necessary for a low cost ZigBee logical device.
The CC2420DB is also furnished with connectors where the internal signals on the PCB are
available for further sensor daughter boards addition to easy add additional profile hardware
when desired. The details of the CC2420DB features are described in the CC2420DBK User
Manual. Please refer to the references section of this document.
The CC2420 ZigBee DK provides, in addition to five CC2420DB’s, a CC2400EB that together
with CC2420EM can utilize the capability of running Chipcon’s Packet Sniffer with the new
ZigBee packet parser addition.
This User Manual describes how to use the CC2420 ZigBee DK Development Kit. The
Figure 8 Wireless Z-Stack, tools and documentation will be provided as a distribution
package available for download from the Chipcon ZigBee Developer Site after the purchase
of this kit. When purchased, customers will be provided with a user name and password to
access this site to download the Z-Stack End Customer distribution package. The Chipcon
ZigBee Developer site will be available in the beginning of October.
Please refer to the reference section of this document for links to Atmel’s documentation on
how to use their tools.

Important:
Contact your local telecommunication authorities before transmitting an RF signal to ensure
that there are no local restrictions on the use of the 2.400 –2483.5 MHz ISM band. The
CC2420 operates in the 2.4 GHz frequency band. Although this frequency band is usually
described as “world-wide”, some countries do not allow unlicensed operation in this band.

Hardware Overview
The hardware platform of CC2420 ZigBee DK is based on already established Chipcon
CC2420 kits. Detailed information about the hardware and software included in this kit can be
downloaded from the Chipcon CC2420 product site.
http://www.chipcon.com/index.cfm?kat_id=2&subkat_id=12&dok_id=115
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. 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.
