32-bit All Flash MCUs offer low standby current

Santa Clara, Calif.—NEC Electronics America Inc. expanded its lineup of low-power 32-bit V850ES/Jx3 All Flash microcontrollers (MCUs) with the V850ES/Jx3-L devices, which offer low standby current to help meet stringent power requirements in battery-backed multiphase electricity meters, high-end blood glucose meters, test and instrumentation equipment, point-of-sale systems and other high-end portable devices.

Backward compatibility with earlier generations of NEC Electronics' V850 All Flash MCUs provides designers with an easy upgrade path, while compatibility with other MCUs in the V850ES/Jx3 lineup gives designers the flexibility to select from a variety of compatible devices with higher performance and up to 1-Mbyte of on-chip memory.

Due to improvements made by NEC Electronics, the V850ES/Jx3-L devices consume 0.9mW of power per Dhrystone MIPS (DMIPS) during active operation, and 1.5 microamperes in standby mode. In addition to NEC Electronics' V850ES RISC CPU core and a pipeline architecture that executes up to 43 DMIPS (1.1) at clock speeds ranging from 5 to 20-MHz, the V850ES/Jx3-L MCUs offer flash memory capacities of 128 or 256 Kbytes, embedded RAM up to 16 KB, operating voltages from 2.2 to 3.6V and an I/O tolerance of 5V. The MCUs also feature enhanced, integrated DSP capability, including divide/multiply functions for high-end applications such as motor control and metering.

The MCUs are available in 80- and 100-pin LQFP packages.

Pricing: Varies according to memory configurations. For example, the 100-pin V850ES/JG3-L MCU with 256-Kbytes of flash memory and 16-Kbytes of RAM is $6 each in sample quantities.
Availability: Mass production of the 100-pin version is scheduled for the end of July 2008. Dedicated starter kits are expected to be available in summer 2008.
