TI lancerer ultra low-power MCU-platform med FRAM-hukommelse
Wolverline kalder Texas Instruments nye MSP430 microcontroller-platform, som firmaet hævder har en effektforbrug, der er mindst 50 procent lavere end andre controllere på markedet (in english).
Imagine a device worn on your finger that allows intuitive, touch-free interaction with the digital world. Imagine a solar panel the size of a microcontroller that enables environmental intelligence in any building. Imagine integrating carbon monoxide sensing, thermostat control and biometric security capabilities to a smoke detector without increasing its size.
This smarter, greener, battery-free world according to Texas Instruments (TI) becoming a reality with the world’s lowest-power microcontroller platform from Texas Instruments.
Codenamed 'Wolverine' for its aggressive power-saving technology, this 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 µA/MHz active power consumption). The first devices based on this platform will be the MSP430FR58xx microcontroller series with expected availability in June 2012.
- Everyday devices such as glucose meters and smoke detectors are seeing increased levels of performance with 10-20 years of battery longevity, and this trend is trickling into a myriad of other applications, says Kevin Wang, chief analyst, iSuppli China.
- The revolutionary ‘Wolverine’ low-power architecture from TI is setting a new industry standard and will enable a proliferation of ultra-low-power products. From consumer to medical to industrial, the sky is the limit.
TI claims, that tee '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.
The extreme low power consumption is realized by the use of different technologies:
• Innovation with unique ultra low leakage (ULL) process technology. TI developed this 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.
• Unparalleled performance and reliability with unified FRAM. 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.
• Proven MSP430 ultra-low-power system heritage, peripherals and software for easy development. TI’s MSP430 platform has been the low-power leader for more than a decade. This new ultra-low-power architecture dramatically reduces power consumption with a fast wakeup time of 6.5µs and high precision peripherals such as internal power management and a 12-bit analog-to-digital converter (ADC) at 75µA. All of TI’s 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 significantly ease design and shorten time to market.
MSP430FR58xx microcontrollers based on the 'Wolverine' technology platform will be available for sampling in June 2012.
