CEL’s MeshConnect™ EM357 Mini Modules are
the industry’s smallest Silicon Labs® Ember based
modules. Based upon the Ember EM357 ZigBee
SoC, these modules combine advance silicon
architecture (Cortex-M3) and the industry’s premier
ZigBee stack, EmberZNet PRO. With a small
footprint (<400mm2) and advanced RF performance
(link budget 123dB), CEL’s Mini Modules challenge
the merits of a discrete implementation.
As Silicon Labs’ module partner, CEL has companion
kits that enable the Mini Modules to be directly
integrated into Silicon Labs’ own development kits
for easy integration and development within the
Insight™ tool chain.
These modules are available in low and high
output power options (+8dBm and +20dBm), to
accommodate various range and performance
requirements.
The EM357 SoC IC consists of an RF transceiver
with a baseband modem, a hard-wired MAC and an
embedded 32-bit ARM® Cortex™-M3 microcontroller
with internal RAM (12kB) and flash (192kB)
memory. It provides numerous general-purpose I/O
pins and peripheral functions such as timers and
UARTs enabling customers to access its rich mix of
on-chip functionality.
CEL’s MeshConnect™ line of 802.15.4/ZigBee
products delivers industry-leading range, high
performance, and a rich feature set at low cost.
CEL’s design examples, reference designs, and
engineering support help customers get their
product designs to market quickly. Based upon the
industry’s premier ZigBee stack (EmberZNet PRO™)
key applications include Smart Energy (thermostats,
meters, in-home displays and smart plugs), LED
lighting control, solar/wind power, HVAC control,
and security systems. MeshConnect certified and
qualified modules enable customers to reduce their
design and certification costs of development as
well as development risk, while reducing time to
market.
