Circuit Description
The schematic diagram in figure 3 details the electrical
configuration of the Pixie and Pixie Lite modules. Items
shown in blue are options and are not fitted as standard.
For stock management reasons, units may occasionally
be supplied with unrequested options fitted.
The EasyBee radio provides PHY and MAC layers
conforming to the IEEE 802.15.4 standard.
electrically identical to the EasyBee radio marketed by
FlexiPanel Ltd and for which detailed documentation is
separately available.
The EasyBee radio in turn matches both the PICDEM Z
radio board and the reference circuit supplied by
Chipcon, suppliers of the circuit’s main component, a

CC2420 MAC/PHY transceiver. The main difference is
the smaller size.
The remainder of the circuit, centered on the
PIC18LF4620, is intended to provide the higher stack
layers. In the case of ZigBee, these would be the NWK,
APS, APL and ZDO layers. In addition, it provides the
application layer or, if the application resides off-chip, an
interface to it.
The OEM may choose to develop firmware in-house,
make use of free Microchip’s ZigBee Stack, and/or
make use of the free firmware solutions provided by
FlexiPanel Ltd as needed.
The circuit is electrically very similar to the PICDEM Z
Microchip ZigBee Stack evaluation kit, with the following
