Indice Semiconductor, Maker Of Energy-Saving Chips, Raises $6M Series A

By Catherine Shu for TechCrunch   Indice Semiconductor has raised a $6 million Series A to focus on marketing its chips, which use an algorithm that the company says can help appliances save energy. The round was led by Allen Alley, the co-founder and former CEO of Pixelworks and included participation from Australian venture capital firm rampersand. The capital will be used to increase Indice’s sales team in the U.S. and Asia Pacific region in order to target original equipment manufacturers and product designers. So far, Indice has marketed chips with its Continuous SigmaTM algorithm to the lighting industry, but is planning to expand to amplifiers, electric vehicles, and the Internet of Things. Indice Semiconductor, which was founded in Melbourne, Australia, also announced that it is relocating its headquarters to Tualatin, Oregon, and has hired Alley as its executive chairman. Indice Semiconductor hopes to stand apart from its peers (including Texas Instruments, Analog Devices, and Cirrus Logic) with its patent-pending Continuous SigmaTM algorithm. So far, Indice has sold 1 million chips using Continuous SigmaTM.  Continuous Sigma improves performance in digital-to-analog (DAC/ADC) applications, which means that it can be used in hardware in verticals ranging from connected devices and electric vehicles to lighting and amplifiers. “Continuous SigmaTM is a simpler encoding method than the commonly used Successive Approximation Registar (SAR) found in many wearable devices, and has a higher performance than the Delta Sigma encoding method (around since the 1970s), which is found in audio applications, power supplies, and motor control,” a spokesman for the company told TechCrunch. “For the end user this could mean anything from more effective noise cancelling headphones than what we currently see on the market to smarter, more efficient wearable devices.

The Internet of Things and wearable devices demand technological innovation

The development of wearable devices is driving lower power memory innovation, according to EETimes' Gary Hilson. Ramon Ramirez, IDC analyst, believes that the industry is trying to shrink currently used devices such as laptops, tablets and smartphones into something which is smaller and wearable. However battery and memory limitations mean there is still much opportunity for innovation. Simple devices such as Fitbits and Pebble watches are already available on the market, but in future there will likely be more demand on the capabilities of these technologies, requiring a smaller form factor and low power draw. Alan Niebel, CEO of WebFeet Research, believes there is no one size fits all solution, allowing for the possibility of many different industry players and types of memory for different applications. Read the full EETimes report here. With so much opportunity to for growth, there are exciting times ahead for those involved in the development of technology for the Internet of Things (IoT) and wearable devices. While it hasn't dabbled in IoT or wearables, Indice Semiconductor has over the years developed technologies for the lighting, audio and signal conversion space which specifically address power density and efficiency, while maintaining compact form factors and true thermal management. One of Indice's latest offerings, the Power Amplifier 'Blade' is a powerful demonstration of just how much power the company is able to pack into an incredibly small, 24mm x 22mm module. While not small enough to wear, the Blade will certainly open up a whole new world of design flexibility for amplifier manufacturers.
