California Eastern Laboratories (CEL) recently announced sample availability of its MeshConnect™ EM357 Mini Modules, which are built around the EM357 ZigBee chip from Ember Corporation. Applications include energy management, smart home, LED lighting, and machine-to-machine applications.
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. The high-power modules provide a market leading +123 dB link budget and run using the EmberZNet PRO™ ZigBee stack.
A striking feature of this module is that the high-power (+20dBm) and low-power (+8dBm) versions of the chip have the same footprint. In addition, the CEL module features the smallest footprint of all Ember-based modules today. Rich Howell, director of business development at CEL, tells me that this makes the module comparable with discrete solutions for designs with tight space-constraints.
Pricing and Availability
CEL is sampling MeshConnect EM357 Mini Modules now. Mass Production begins in July 2012. Part numbers are ZICM357SP0-1 (low-output power) and ZICM357SP2-1 (high-output power). Pricing is <$15 in thousand-piece quantities.
