Santa Clara, CA, U.S.A. --- (METERING.COM) --- March 30, 2010 - A total of 78 new members to the V850ES/Jx3 family of 32-bit All Flash® microcontrollers (MCUs) with low power consumption, optimized pin counts and expanded functionality have been announced by NEC Electronics America, Inc. for applications including electricity meters.

This new lineup provides a complete and scalable platform approach for system designers, allowing them to choose the optimum memory, pin count and peripheral combination for their applications. In addition, by sharing the same architecture and development environment, the new MCUs enable easy migration of software and hardware for system designers, contributing to faster time to market at lower cost.

Operating at 20 MHz, the new V850ES/Jx3-L (low power version) MCUs deliver 38 DMIPS of performance while requiring  only 0.9 mW/MIPS, offering approximately 60 percent reduction over the other V850/Jx3 family members that require 1.7 mW/MIPS. Power consumption is 0.7µA in standby mode with the real time counter (RTC) operating. This new low power MCU lineup also offers flash memory sizes up to 512 kB, an RTC with independent power supply pins, an increased number of serial interfaces and optional on-chip USB 2.0 controllers.

The  new family of V850ES/Jx3 MCUs offers lower pin count package options such as the 40 pin quad flat no leads (QFN) measuring 6 mm x 6 mm x 0.75 mm. For applications requiring even smaller and thinner packages, a lineup of ball grid array (BGA) products are available, with options ranging from 64 pins (5 mm x 5 mm) to 113 pins (8 mm x 8 mm), reducing space requirements and enabling design of compact systems. Quad flat package (QFP) options are also available and range from 64 to 144 pins. Prior to these new parts, the V850ES/Jx3 family’s smallest pin-count package was an 80-pin QFP.

With the addition of the new devices, NEC Electronics’ V850ES/Jx3 series now includes 117 MCUs with flash memory sizes ranging from 16 kB to 1 MB and packages from 40 to 144 pins. Increased connectivity is enabled by USB 2.0 host and function options available in the V850ES/Jx3-H and V850ES/Jx3-U series as well as embedded Ethernet MAC in the V850ES/Jx3-E series. The NEC Electronics’ 32-bit family of V850 MCUs provides operating frequencies from 20 to 200 MHz, (38 to 380DMIPS). The common architecture provides a wide range of price/performance points facilitating upward and downward system-migration paths.

Mass production of the initial products is scheduled to begin in June 2010, and additional devices will be introduced throughout 2010.
