California Eastern Laboratories (CEL) announced the production release of its new MeshConnect EM358x Mini modules. As pin-compatible extensions to the company’s line of EM357-based modules, these new devices capitalise on the latest enhancements brought forth by the recently announced EM3588 system-on-chip from Silicon Labs.
Each of these improvements helps to facilitate new ways to link into and control ZigBee network environments within connected home, lighting, building automation, industrial and other M2M (machine to machine) applications.
When compared to their EM357-based predecessors, the new EM358x offerings provide significant increases in embedded memory with over 2,7 times more Flash and five times more RAM. The additional Flash allows for more application storage and over-the-air programming capability without the need for supplemental external system memory.
The added RAM enables the modules to support ZigBee IPv6-based networks (like the ZigBee Smart Energy 2.0 standard). Tasks requiring real-time operating system execution times are also now possible as part of this RAM enhancement. Additionally, larger mesh networks can be supported.
As a final improvement, the EM3588 brings USB capability to the module series. The device’s built-in USB controller allows users to quickly integrate ZigBee into existing devices with USB connectivity. The integration of all of these enhancements reduces overall board space by 20%.
These modules are FCC, IC, CE and iControl certified, and they utilise the ZigBee PRO Stack from Silicon Labs (EmberZNet PRO). Standard and long-range (+8 dBm and +20 dBm) options are available to allow designers to choose the radio performance that best suits their range requirements.
