Free demonstrator aids MCUs use in medical designs

Eight 32-bit V850 microcontrollers have been added to Renesas Electronics America Inc.'s V850 J Series. Suitable for applications such as portable healthcare equipment and healthcare systems, especially portable measurement and monitor devices such as blood glucose meters, the MCUs provide extended battery life memory for data storage and increasing application needs.

The V850ES/Jx3-L MCUs are an extension of the low-power V850ES/Jx3-L 32-bit MCUs that were introduced in early 2010 and are designed for low-power, portable applications with high-density memory from 768 KB flash/80KB RAM to 1 MB flash/80KB RAM to support increasing memory demand.

Four of the MCUs are equipped with a USB 2.0 function interface to support communications.

The company is also running a free promotion of a V850ES/Jx3-L Low Power Demonstrator Kit http://www.am.renesas.com/products/tools/introductory_evaluation_tools/renesas_demo_kits/v850es_jx3l_lpd/v850es_jx3l_lpd.jsp, which enables users to measure current consumption of different MCU operation modes and illustrates many features supporting low-power system design.   

The USB support enables healthcare systems to support patient-doctor information exchanges and the 32-bit processing power can support graphic computation for different displays from segmented LCD to dot-matrix and OLED.

These devices achieve a power consumption of 0.9 milliwatts per 1 MIPS at 20 MHz. Improved peripheral functionality, such as USB 2.0 and real-time counter functions, enable these devices to achieve a low current consumption of 0.7 µA (with only the real-time counter operating) in standby mode. These MCUs also support 2.0 volt (V) low-voltage operations when operating at 2.5 MHz, contributing to longer battery operating times in portable and battery-operated electronic equipment.
 
Renesas Electronics’ V850 J Series now includes a total of 125 products ranging from 16 KB to 1 MB of flash memory, from 8 KB to 80 KB of RAM, and from 40 to 144 pins. Software can be re-used within the same series.
