Ultra-low power MCUs for mobile smart metering

MSC is offering eight Renesas ultra-low power 32-bit MCUs in the V850ES/Jx3-L series for mobile smart metering and medical applications with high memory demand.

The typical current consumption of the MCUs with up to 1MB flash memory and 80KB of RAM is 14mA and the standby current 1.5uA.

Four of the new V850ES/Jx3-L devices, designed for clock frequencies from 2.5 to 20MHz, are available with a USB 2.0 full-speed communication interface, which supports simple data exchange in healthcare systems according to the Continua Alliance standard.

For fast and easy evaluation, 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 512KB 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 optimised for use with a Minicube2 debugger, the QB-MINI2-EA.
