EM300 Series

Overview—EM300 Series ZigBee SoCs

The EM351 and EM357 ZigBee chips from Ember are the industry’s first ARM Cortex-

M3 based family of SoCs delivering unmatched performance, power consumption

and code density in a compact package.

The EM351 and EM357 combine a 2.4 GHz IEEE 802.15.4 radio transceiver with a

32-bit microprocessor, Flash memory and RAM with powerful hardware supported

network-level debugging features. This, combined with the powerful ecosystem of ARM

tools, enables OEMs to simplify development and accelerate time to market.

The EM300 family is tightly integrated with EmberZNet PRO, Ember’s ZigBee compliant

mesh networking software which is the most deployed ZigBee platform in the market.

Low Power, High Total Link Budget, Robust Co-existence

The EM300 family delivers outstanding, industry leading performance with a configu-

rable Total Link Budget up to 109 dB, while maintaining the highest level of integration

requiring minimal external components. The high transmit power virtually eliminates

the need for an external Power Amplifier (PA) in most applications especially in Europe

and Asia. Where PA is required, the product is designed to allow an external PA or

Front End Module (FEM) to be easily connected.

The EM300 family offers the lowest sleep current of any ZigBee system in the market.

Developers can take advantage of the integrated EmberZNet PRO networking library

to incorporate short wake cycles. Also, integrated clocks provide optimized wake-

sleep cycles to conserve power. The integrated voltage regulator supports a wide

range of operating voltages allowing hardware designs to be optimized for lithium-ion

or alkaline batteries without additional circuitry.

The EM351 and EM357 ZigBee SoCs are extremely robust providing exceptional

immunity and reliable co-existence with other 2.4 GHz devices in the environment.

ARM Cortex-M3 Processor

The integrated 32-bit ARM Corex-M3 processor provides a very high code density

allowing larger applications, while delivering exceptional performance in a small,

power efficient RISC core. Well recognized for its outstanding computational perfor-

mance and exceptional system response to interrupts the ARM processor enables a

small core footprint and best in class code density. The performance of the Cortex-M3

processor coupled with the performance of the Ember stack helps deliver network

throughput and lower latencies that are unmatched in the industry.

EM351—integrates a programmable ARM Cortex-M3 processor, IEEE 802.15.4 RF

radio transceiver, 128 KB Flash and 12 KB RAM and EmberZNet PRO network

protocol stack supporting the ZigBee PRO Feature Set

EM357—optimized for applications that require more memory, it has 192 KB Flash

but incorporates all the other characteristics and features of the EM351
