MeshConnect IC Block Diagram
Integrated RF Transceiver/MCU
for ZigBee/IEEE 802.15.4 Networks
CEL’s MeshConnect ICs combine a power-
ful RF transceiver with an industry-standard,
8051-based 8-bit microprocessor. Available in
a QFN48 or VFBGA72 package, these low cost,
highly integrated System-on-Chip radios can help
simplify your design, reduce its size, lower its
power consumption, and reduce
your overall system costs.
At +8 dBm, the MeshConnect IC delivers the
industry’s leading output power. Combined
with excellent –98dBm receiver sensitivity,
the MeshConnect IC provides a best-in-class
link budget of 106 dB. The high output power
ensures immunity to interference from other
2.4GHz transmissions, while the high sensi-
tivity and link budget can help eliminate the
need for power amplifiers and peripheral range
extension components.
With 1Mbps data rates and an on-chip Voice
CODEC the MeshConnect IC can handle high-
bandwidth voice/data transmission. A variety
of other robust peripherals — battery monitor,
temperature sensor, RSSI and AES encryption
engines — are all designed to help lower your
system component count.
MeshConnect ICs are ideal for home and building
automation, lighting control, solar/wind, HVAC
control, security networks, cable replacement,
video, asset management, AMR/AMI, remote
sensing and voice applications. With their low Tx,
Rx and standby power consumption, they’re an
excellent choice when battery life is critical.
MeshConnect ICs are part of a broad family of
CEL ZigBee products, including integrated radio
modules and discrete power amplifiers, LNAs and
RFIC switches for ZigBee range extension.
