Texas Instruments Inc. (TI) announced a collaboration with Ember Corp. to unveil what it touts as the world's lowest power consuming ZigBee networking and microcontroller (MCU) platform.

Ember paired its em2420 802.15.4/ZigBee-compliant semiconductor platform with TI's MSP430F161x series of ultra-low power MCU for developers building ZigBee applications that require the lowest possible power requirements.

The new dual-chip network module provides a complete, integrated MSP430 MCU, a radio and the ZigBee software platform for OEMs wishing to tap into the market for ZigBee/802.15.4 wireless sensing and control applications. To reduce the device's footprint and BoM, the MSP430F161x MCU series integrates all peripherals, including high-performance analog and up to 55KB of flash memory, which reduces the need for EEPROM. The device also features on-chip, high-precision control peripherals such as a 12bit 200ksps analog to digital converter (ADC) and a 12bit digital to analog converter (DAC) with a settling time of 1 microsecond.

According to the press release, the MSP430F161x MCU series offers the industry's lowest current consumption with 1.1?A standby mode with real-time clock operation, as well as a 300?A (1 MHz) active mode that allows engineers to tune system clocking to meet precise power requirements. With fast instruction execution enabled by a 16bit RISC CPU, a start-up time of less than 6?s from standby and a fully synchronized, high-speed system clock, the chip's total power consumption is 10 times lower than competing devices. CPU power requirements are also kept to a minimum by the DMA controller which allows movement of data from one memory address to another without CPU intervention, added the two companies.

The 2.4GHz Ember EM2420 is the highest performing, most power-efficient radio transceiver in its class, providing a flexible, simple interface to a wide range of microcontrollers. The new EM260 is a ZigBee wireless network processor for OEMs who have standardized on TI and other select MCU platforms. The processor enables for the first time a ZigBee-compliant network node with "location awareness," which allows for easier commissioning, management and network sub-segmentation. The EM260 also has the highest RF output and Rx sensitivity for power consumption than competitive ZigBee products.

The kit is available now and can be ordered from www.ember.com/products/buynow.html at $4,995 for the JumpStart Kit and $13,950 for the Full Developer Kit.
