Renesas Electronics Europe Launches Unique Microcontroller Evaluation Tool with Integrated Power Measurement Function


RX111 Renesas Promotion Board: cost-effective evaluation for multiple applications

Dusseldorf — Renesas Electronics Europe, a premier provider of advanced semiconductor solutions, today announced the availability of the new RX111 Promotion Board (RPB), a cost-effective evaluation platform designed 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.

Ideal for evaluating the RX111 in low power applications

The RX111 RPB comes with all the software and hardware required to easily 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.

Full-featured RPB

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 the following elements:

• RX111 target board with integrated power measurement

• Renesas C compiler and e2 studio Integrated Development Environment ( limited to 128k code & data after 60 days)

• Graphical Code Generator

• Graphical user interface for the power measurement system

• Free of charge host and peripheral USB sample code

• Low-power demo application

• USB demo application

Renesas RX111 Microcontrollers

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 power applications. The flash memory offers reprogramming across the full voltage range of 1.8 – 3.6v with data flash and a typical endurance of 1 million write erase cycles as well as guaranteed data retention of up to 20 years. The RX111 devices also include an on-chip USB interface along with a wide range of digital and analogue peripherals. It is available in a choice of small package options, supporting package sizes down to 4 mm2 and with flash sizes from 16KB – 128KB.


The RX111 RPB is available now, and can be ordered today with the order code YRPBRX111. All the versions of the RX111 microcontroller are now available in sample quantities. Mass production of the RX111 Group will be available by the end of 2013.
