NEC Announces New Ultra-Low Power VR4181A Microprocessor With 18 Built-in Peripherals

-New System-on-a-Chip Enables High-Performance Multimedia and Internet Capabilities for Next-Generation Automotive, Industrial and Portable Applications-


TOKYO and SANTA CLARA, Calif. - January 21, 2002 - Expanding its integrated MIPS®-based VR SeriesTM microprocessors, NEC Corporation and its wholly owned semiconductor affiliate in the United States, NEC Electronics Inc., today introduced the VR4181ATM 64-bit microprocessor. The VR4181A product is the latest addition to NEC's VR4100TM family of processors designed to provide low-power operation with high integration. The microprocessor integrates more than 18 peripherals and interfaces with a powerful VR4120ATM processor core. As a result, this processor provides a unique system-on-a-chip (SoC) solution for portable devices, industrial applications, automotive communications and telematics applications.
"The performance-to-power consumption ratio and integrated peripheral support of the VR4181A product deliver multimedia and Internet access capabilities that make it a strong choice for high-performance, power-sensitive portable applications, and industrial controls and displays,"said Karl Auker, associate general manager for NEC Electronics' VR Series strategic business unit. "Additionally, OEMs can leverage the processor's numerous peripherals and interfaces to support advanced telematics applications in next-generation automotive systems."

Manufactured using NEC's 0.25-micron process technology, the VR4181A processor features an optimized six-stage pipeline and a 131-megahertz (MHz) VR4120A-based processor core to deliver 157 million instructions per second (MIPS). However, this high level of performance is achieved with a power consumption of only 500 milliwatts at full clock speed. Power consumption levels for this single-chip solution are even lower in the standby, suspend and hibernate modes, where power consumption levels are measured in microwatts.
The VR4181A microprocessor's effective performance level increases even more over its predecessor, the VR4181 processor, thanks to its larger 8-kilobyte (KB) instruction cache and 8 KB data cache. With support for the MIPS I, II, III and MIPS 16 instruction sets, the product gives designers a range of options for software development.
Design flexibility is further enhanced with the processor's support for several memory types, including flash, SRAM, SDRAM and SyncFlash. The product uses a small 240-pin FPBGA package to accommodate the space restrictions characteristic of most portable and automotive designs.

New Processor Supports Broad Range of Peripherals
Demand for audio, communications and telematics systems with support for voice-activation, MP3 audio playback, Internet radio, Web browsing, text-to-speech and wireless access protocol (WAP) is increasing. To accommodate these requirements, the VR4181A microprocessor has more than 18 built-in peripherals and interfaces including the following:
  • Multimode LCD and LED controllers
  • Touch-panel and keyboard controllers
  • Universal Serial Bus (USB) host and client
  • Three universal asynchronous receivers-transmitters (UARTs) and a clocked serial interface (CSI)
  • CSI and I2C interface
  • Audio Codec '97 (AC97) interface, three pulse-wave modulation channels, and I2S
  • IrDA®
  • External direct memory access (DMA) interface
  • General-purpose input/output (GPIO) interrupts
  • Two CompactFlash connections
To further assist OEMs with the design of next-generation automotive systems, NEC also offers VR4181A-compatible middleware for voice recognition, text-to-speech and Web-browsing application development. This processor will also be supported by popular operating systems, including Windows® CE .NET, Linux®, QNX® and Vx WorksTM.

Pricing and Availability
Engineering samples of NEC's VR4181A processor are available now with volume production scheduled for April 2002. The product is priced at U.S. $20 in 10,000-unit quantities. Pricing and availability are subject to change.
