Actel Fusion field-programmable gate arrays available from Caelera

Supplier News

Actel have announced that Sanyo Denki have chosen mixed-signal Actel Fusion field-programmable gate arrays (FPGAs), available from Caelera , for implementation in their new RA035 position detection device (encoder) for servo motors for industrial applications.

Selected for its low power, high accuracy and integration capabilities, the 600,000-gate AFS600 Actel Fusion device serves as the main process circuit, converting signals from the resolver into position data.

In addition to a more than 50% reduction in power consumption versus alternative solutions, the RA035 reduces hazardous waste and eliminates the need for maintenance by enabling the detection of the absolute motor position without a battery. The Fusion-based RA035 also provides ecological advantages—reducing energy consumption equivalent to 190 tons of CO2 emissions per year.

Sanyo Denki are considering the installation of mixed-signal Fusion FPGAs for future products, following the development of the RA035. The company is also evaluating Actel's ARM processor-enabled FPGAs for their next-generation designs.

"Reducing power to make our products environmentally friendly is one of our principles for product development. The adoption of Actel's single-chip, mixed-signal Fusion FPGA in our new RA035 has enabled dramatic reductions in power consumption compared to alternative solutions," said Makiuchi, Servo Systems Division, 1st Design Dept. Chief engineer, Sanyo Denki.

"Significantly reducing product size and component count, one Fusion device can also manage multiple functions, such as flash ROM, CPU, and communications gate array, each of which used to require an individual IC. Due to their leading power, flexibility, integration and accuracy advantages, we plan to continue using Actel's flash-based FPGA technologies for our next-generation designs."

"Sanyo Denki's selection of our Actel Fusion FPGAs underscores the power consumption and power management advantages that mixed-signal, flash-based FPGAs provide for today's power-sensitive industrial applications," said Masa Katayama, Area Sales Director, Japan, at Actel.

"For high-precision industrial applications, Actel's mixed-signal Fusion FPGA offers the low-power consumption, intelligent system and power management, high accuracy and integration required by the growing community of global industrial designers."
