Wolverine microcontroller platform slashes power by 50 percent
February 28, 2012 // Paul Buckley
Texas Instruments Incorporated has unveiled feature-packed MSP430 microcontroller platform with the aim of pushing ultra-low-power limits, bringing consumers one step closer to a battery-free world.
TI says it is codenaming Wolverine for this aggressive power-saving technology, the ultra-low-power MSP430 microcontroller platform offers at least 50 percent less power consumption than any other microcontroller in the industry (360 nA real-time clock mode and less than 100 uA/MHz active power consumption). The first devices based on this platform will be the MSP430FR58xx microcontroller series with expected availability in June 2012.
The Wolverine platform provides the lowest power consumption in any use case when compared to any microcontroller in the industry – lowest active power, standby power, memory power and peripheral power. For example, typical battery powered applications spend as much as 99.9 percent of their time in standby mode, and "Wolverine"-based microcontrollers consume 360 nA in standby mode, more than doubling battery life.
TI developed the ULL technology that offers a 10x improvement in leakage and optimized mixed signal capabilities. The improved 130 nm process technology, ultra-low-power MSP430 architecture and more than 30 power-optimized analog and digital components combined are a few of the integrated elements that deliver the dramatic power reduction.
Taking advantage of FRAM, the world's lowest power memory, Wolverine-based microcontrollers can operate at less than 100 µA/MHz in active mode and consume 250x less energy per bit compared to Flash- and EEPROM-based microcontrollers. In addition to these power advantages, FRAM is 100 percent non-volatile, which gives developers the low power, speed and flexibility of SRAM while retaining the key no-power storage capability of Flash. Customers are not limited to the specific ratios of program-to-data memory inherent to traditional embedded systems – they can change this ratio at any time in the design cycle.
The MSP430 platform has been the low-power leader for more than a decade. This latest ultra-low-power architecture dramatically reduces power consumption with a fast wakeup time of 6.5 µs and high precision peripherals such as internal power management and a 12-bit analog-to-digital converter (ADC) at 75 µA. All MSP430 microcontrollers are also augmented by the MSP430Ware software and resource package, as well as low-power code optimization software tools. MSP430Ware enables developers to immediately access and easily filter through all MSP430 microcontroller design resources by device, tool or software library to ease design and shorten time to market.
MSP430FR58xx microcontrollers based on the Wolverine technology platform will be available for sampling in June 2012. Developers looking to get started with ultra-low-power designs can begin development with the company's existing portfolio of nearly 500 MSP430 microcontrollers. Design ease is a fundamental offering of MSP430 microcontrollers, with a wide range of tools, software and support to help customers begin development quickly.

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
