NEC Electronics Inc. is extending its VR series microprocessors into the realm of ultra low power to address portable, automotive, and industrial applications that have strict power constraints. But skimping on power doesn't have to mean less performance, according to NEC. The 64-bit VR4181A, being unveiled today, uses the 0.25-micron VR4121 CPU core to offer speeds up to 131 MHz and 157 mips, and leverages its 16-bit MIPS instruction set. But the new version consumes as little as 500mW in full operation, NEC said. The '4181A also integrates more than 18 peripherals selected to support a variety of multimedia, telematics, and Internet applications withing its target markets. "This processor is designed to suit any kind of application that needs a user interface, where low power is important, like touch panels, LCD controllers, Web Pads, and point of sale terminals," said Arnold Estep, senior manager of VR microprocessors at NEC in Santa Clara, Calif. "It's at a price point where you can find other integrated devices, but none as complete or as low power."
