Pocatello, Idaho - AMI Semiconductor's AMIS-30621 is a microstepping motor driver for remote and multiple-axis positioning applications such as those involved in automotive headlamp leveling and swiveling, cruise control and idle control. Marketed as the first single-chip device for local interconnect networks, it integrates bus connection, positioning electronics and the motor-driving stage in a single SOP-20 package. AMI says the device will provide better electromagnetic-compatibility performance than solutions with centrally placed drivers. It's priced at $2.20 each in lots of 10,000. Evaluation boards are available on request.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
