SoC
EM351 & EM357 - 32-bit ARM Cortex-M3 based ZigBee system-on-chips combine a 2.4 GHz 802.15.4 radio with 128 KB/192KB Flash, 12 KB RAM and EmberZNet  PRO stack supporting the ZigBee PRO Feature Set and deliver outstanding performance with a total Link Budget up to 110 dB and sleep current as low as 400nA.

NCP
Ember’s latest and best performing ZigBee SoCs (above) can now also be used as a network co-processor, using Ember’s EZSP protocol, supported by EmberZNet PRO 4.3.0 and later. This is designed to make migration from EM260 NCP easy, and in addition, on EM357 the additional flash is used to provide more token space, enabling support for 50 link keys and bindings, necessary for trust center functionality in large ZigBee Smart Energy networks.

True ZigBee system-on-chip, combining a 16-bit micoprocessor, Flash, RAM, a 2.4GHz 802.15.4 radio, and numerous debugging and development features. Application development is supported by a C-language development environment that includes the EmberZNet stack.
