Eight new V850ES/JG3-L MCUs for portable smart metering and medical applications

The typical current consumption of the MCUs with up to 1 MB flash memory and 80 KB of RAM is only 14 mA and the standby current 1.5 µA. Furthermore, four of the new V850ES/Jx3-L devices, designed for clock frequencies from 2.5 MHz to 20 MHz, are available with a USB 2.0 Full Speed communication interface, which, among other things, supports simple data exchange in healthcare systems according to the Continua Alliance standard.

For fast and easy evaluation, among other things, MSC provides a free V850ES/Jx3-L low power USB stick demonstrator to developers upon request. With the help of this kit, which is based on a V850ES/JG3-L MCU with 512 KB flash memory, the different standby modes can be tested. The kit supports current consumption measurement with use of an ampere meter. It also demonstrates RAM retention and real time clock operation in the lowest power mode.

As additional development support, MSC provides a QB-V850ESJG3LUSB-TB target board, which is optimized for use with a MiniCube2 debugger, the QB-MINI2-EA.
