Renesas Electronics Corp. has unleashed what it says is a unique and cost-effective evaluation platform intended to facilitate the evaluation of Renesas' RX111 MCUs in applications such as mobile healthcare, smart meters and industrial and building automation. The RX111 Promotion Board (RPB) comes with an integrated power measurement tool, enabling the user to easily measure the power consumption of the MCU running on the RPB, the company indicated.

The RX111 RPB features 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 RX111 MCU group claims to deliver 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 MCU performance in their low-end 32bit embedded applications, including mobile health care, smart meters, sensors/detectors, and industrial and building automation.

The RPB includes a Segger J-Link on-chip debug function with a target RX111 MCU. It offers both host and peripheral USB connectors, as well as a supercap to allow continued operation when the power is removed. For example, the RX111 RPB can transfer a file from memory to a USB thumb drive using only the supercap as the power supply source. The RX111 is one of the few ultra-low-power MCUs to offer USB host support.

The RX111 RPB comes with a number of sample applications including a low-power demo with a PC graphical user interface (GUI) to allow developers to measure of the power consumption of the target RX111 in each of its low-power modes. This allows users to switch the MCU into a variety of low-power modes and display the power consumption on a GUI window.

The RX111 is the latest member of the RX family of 32bit MCUs, and brings True Low Power technology to the 32bit world. The RX111 devices achieve current consumption as low as 100?A/MHz in active mode and 0.66?A in RTC mode with all SRAM maintained. Its wake up time is just 4.8?S from the lowest power modes, making it ideal for a 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 one 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. The RX111 Group is available in a choice of small package options, supporting package sizes down to 4 x 4mm and with flash sizes ranging from 16-128KB.

The RX111 RPB is available on the Renesas website, and can be ordered with the order code YRPBRX111. All the versions of the RX111 MCU Group are available in sample quantities priced at $15 per board. Mass production of the RX111 Group will be available by the end of 2013.
