Functional Block Diagram
Circuit Description
The functional block diagram in figure 2 summarizes the
electrical EasyBee module. The actual circuit closely
follows the reference design specified by ChipCon AS
for single ended operation with discrete balun. (See
bibliography.) Actual component choices may differ.
The module is also electrically identical to the PICDEM
Z radio board supplied by Microchip Technology Inc.
The main difference is the smaller size.
If the device being designed is to be battery powered,
aim to use lithium batteries rather than alkaline since
they generally have much better ageing characteristics
and reduced voltage decline over their lifetime.
Interfacing to the RF module
Refer to ChipCon’s documentation for information on
how to interface to the CC2420 module. Most ZigBee
stack firmware also details how to communicate with the
CC2420 using the SPI port.
Development Kits
OEMs intending to use EasyBee with Microchip PIC
microcontrollers can use the PICDEM Z ZigBee
development kit available from Microchip Technology.
Microchip also provide a free ZigBee stack.
EasyBee DEMO version of the module is designed to
plug directly into the PICDEM Z motherboard. Migration
to EasyBee simply requires choosing an appropriate
PIC microcontroller for the application.

OEMs wanting to use EasyBee with other baseband
microcontrollers should use ZigBee stack software
which is designed for interfacing to the CC2420 chip.

kit is available.
Circuit diagnosis is much aided through the use of a
packet sniffer such as Pixie Sniffer.
