Microcontroller evaluation tool incoporates integrated power measurement function

September 23, 2013 // By Paul Buckley
Renesas Electronics Europe has introduce the RX111 Promotion Board (RPB), a cost-effective evaluation platform to facilitate the evaluation of Renesas’ RX111 microcontrollers (MCUs) in a wide variety of applications.

The RX111 RPB comes with an integrated power measurement tool, enabling the user to easily measure the power consumption of the microcontroller running on the RPB.

The RX111 RPB comes with all the software and hardware required to develop and evaluate applications on the RX111 MCUs. Designed to support a broad range of markets, the new RX111 group delivers a combination of ultra-low-power consumption, on-chip connectivity and superior performance at attractive price points. Developers can use the RX111 RPB to test microcontroller performance in their low-end 32-bit embedded applications, including mobile health care, smart meters, sensors/detectors, and industrial and building automation.

The new RPB includes a Segger J-Link on-chip debug function with a target RX111 microcontroller. It offers both host and peripheral USB connectors, as well as a supercap to allow continued operation when the power is removed. The RX111 RPB comes with a number of sample applications, including a low-power demo with a PC graphical interface to allow developers to measurement of the power consumption of the target RX111 in each of its low power modes.

The RX111 RPB includes a RX111 target board with integrated power measurement plus a Renesas C compiler and e2 studio Integrated Development Environment ( limited to 128k code & data after 60 days).  In addition there is also a Graphical Code Generator and a graphical user interface for the power measurement system plus a free of charge host and peripheral USB sample code.

A low-power demo application and an USB demo application also included.

The RX111 is the newest member of the RX family of 32-bit microcontrollers, optimised for extremely low power, low cost applications. The RX111 devices achieve current consumption as low as 100 µA / MHz in active mode and 0.66 µA in RTC mode with all SRAM maintained. Its wake up time is just 4.8 µS from the lowest power modes, making it ideal for a wide range of low
