Dialog Semiconductor introduces the world’s lowest power Bluetooth® Smart Chip
Kirchheim unter Teck, Germany, 21 May 2013 – Dialog Semiconductor plc (FWB: DLG), a provider of highly integrated power management, audio and short-range wireless technologies, today launched SmartBond™ (part number DA14580) – the world’s lowest power and smallest Bluetooth® Smart System-on-Chip (SoC) which more than doubles the battery life of an app-enabled smartphone accessory or computer peripheral in comparison to competing solutions on the market. It’s designed to connect keyboards, mice and remote controls wirelessly to tablets, laptops or Smart TVs and enable consumers to use innovative new apps on their smartphones and tablets ‒ connected with watches, wristbands and smart tags ‒ to “self-track” their health and fitness levels, locate lost keys and much more besides.
SmartBond is the first Bluetooth Smart solution to break the 4mA current barrier for wireless transmission and reception, enabling designers to double a product’s battery life or reduce the number and size of cells required. Its unique low power architecture draws just 3.8mA at transmission and reception – 50% less than other Bluetooth Smart solutions on the market – with a deep sleep current of under 600nA. This means a 225mAh coin-cell battery in a product sending 20 bytes of data per second would last 4 years and 5 months in comparison to just 2 years with previous generations of Bluetooth Smart technology.
The DA14580 features a power management block, including a DC-DC converter and all the necessary LDOs, reducing the need for external components and the overall bill of materials. By precisely switching on and off power delivery to each block on the chip, Dialog is able to reduce energy consumption to a bare minimum. SmartBond works at much lower voltages than was previously possible – down to 0.9V – enabling the use of just one alkaline or NiMH cell AA battery instead of two in computer or smart TV peripherals. This opens up exciting new possibilities for designers to create ultra compact and novel form factor products while reducing the total system costs. Alternatively, energy harvesting techniques that scavenge solar or kinetic energy can be used to power the rechargeable battery powering the system.
The DA14580 also has a size advantage. It comes in three different form factors – the smallest Wafer-Level Chip-Scale (WL-CSP) is just 2.5 X 2.5 X 0.5mm. This enables Bluetooth to be now added to the most space-constrained wireless accessories.
Sean McGrath, Vice President and General Manager of the Connectivity, Automotive and Industrial Business Group at Dialog Semiconductor, commented, “Dialog is continuing to diversify its product portfolio with the launch of SmartBond. We’ve been able to leverage our low power expertise in the smartphone, tablet and home wireless sensor network markets to develop this Bluetooth Smart System-on-Chip, which breaks records in terms of energy consumption and die size. We’re already engaged with a number of tier one customers in the accessory and peripherals sectors.”
Shinichi Kawanishi, Manager of the Connectivity Modules Products Department at Murata Manufacturing Co. Ltd said, “We’re really looking forward to being a key contributor to this high growth market by releasing a series of lower power and more compact Bluetooth low energy modules as a result of our partnership with Dialog Semiconductor and their competitive DA14580 device.” The inclusion of a 32-bit ARM® Cortex™ M0 core in combination with on-chip One-Time Programmable (OTP) memory provides exceptional design flexibility and eliminates the need for an external processor in the system while reducing costs. Dialog is already partnering with Murata – a world leading wireless module maker – to develop small form factor modules, enabling ODMs with little RF system knowledge to integrate certified solutions quickly into their products.
The adoption of Bluetooth Smart is set to grow rapidly, with over 350 million Bluetooth Smart ICs projected to be shipped cumulatively by the end of 2016 according to IHS Inc. (NYSE: IHS).
Lisa Arrowsmith, Associate Director for Connectivity Research at IHS, commented, “Bluetooth Smart is rapidly gaining traction within fitness and medical devices, with a clear trend away from proprietary technologies. Additionally, with significant penetration of the compatible Bluetooth Smart Ready standard in consumer electronics devices, such as TVs, tablets, laptops and all-in-one PCs, there is a growing opportunity for Bluetooth Smart to be used to enable power-efficient wireless connectivity within high-volume peripheral devices, ranging from remote controls to PC peripherals, as well as being used to enable a huge range of emerging applications”.
