ZigBee Module
The ZMN2405HP 2.4 GHz transceiver module is a low cost, high-power solution for
point-to-point, point-to-multipoint and MESH wireless systems. The ZMN2405HP
module provides the flexibility and versatility to serve applications ranging from cable
replacements to sensor networks. Based on the IEEE 802.15.4 wireless standard
and the ZigBee protocol stack, the ZMN2405HP module is easy to integrate and pro-
vides robust wireless communications including MESH network operation. The
ZMN2405HP also includes Cirronet’s powerful CSM application profile, which elimi-
nates the need for customer firmware programming.

ZMN2405HP Hardware
The major hardware component of the ZMN2405HP is
the CC2430 IEEE 802.15.4 compatible transceiver
with integrated 8051 microcontroller. The ZMN2405HP
operates in the frequency band of 2405 to 2475 MHz
at a nominal output power of 63 mW.
The ZMN2405HP includes a low noise preamplifier in
the receiver path and a power amplifier in the transmit-
ter path, greatly increasing the operating range of the
CC2430. Two crystals are provided to operate the
CC2430, a 32 MHz crystal for normal operation and a
32.768 kHz crystal for precision sleep mode operation.
The ZMN2405HP provides a variety of application
hardware interfaces including an SPI interface, UART
interface, three 12-bit ADC inputs, two PWM (DAC)
outputs, and six general purpose digital I/O ports.
ZMN2405HP Firmware
The main firmware components in the ZMN2405HP in-
clude the ZigBee protocol stack and the Cirronet Stan-
dard Module (CSM) application profile. The ZigBee
protocol stack implements networking and security,
with underlying support from the 802.15.4 Media Ac-
cess Control (MAC) layer. The standard ZMN2405HP
firmware implements a ZigBee full function device
(FFD). This allows the module to operate as either a
coordinator or router. Optional ZMN2405HP firmware
is available that implements a ZigBee reduced func-
tion device (RFD). This allows the module to operate
as an end device. The CSM profile provides an appli-
cation programming interface (API) for all the
ZMN2405HP application hardware interfaces. The
CSM profile includes Network Discovery, Send/Re-
ceive Serial Data, Read/Write SPI Port, Read ADC In-
puts, Write DAC Outputs, Read/Write GPIO and
Module Configuration services. In addition, the CSM
profile provides two sleep modes - timer sleep and in-
terrupt sleep. See the ZMN2405HP ZigBee Module
Developer’s Kit User’s Manual for complete details of
the CSM profile API.

ZMN2405HP I/O Pad Descriptions
RFIO Stripline
The RFIO pad on the radio module is connected directly to an antenna on the host circuit board, or to an MMCX
or similar RF connector. It is important that this connection be implemented as a 50 ohm stripline. Referring to
Figure 3, the width of this stripline depends on the thickness of the circuit board between the stripline and the
groundplane. For FR-4 type circuit board materials (dielectric constant of 4.7), the width of the stripline is equal to
1.75 times the thickness of the circuit board. Note that other circuit board traces should be spaced away from the
stripline to prevent signal coupling, as shown in Figure 4. The stipline trace should be kept short to minimize its in-
sertion loss.
