New ultra low power microcontrollers for smart grid applications from Renesas Electronics


Dusseldorf, Germany — (METERING.COM) — April 17, 2013 – The new RX111 group of 32-bit microcontrollers (MCUs) – the first in the RX100 series – has been introduced by Renesas Electronics for smart metering and other low-end 32-bit embedded applications including industrial and building automation and sensors/detectors.

The RX111 is produced on an ultra low power zero wait state flash process supporting 32-bit power consumption/performance levels as well as fast wake-up, with a wide range of standard peripherals and multiple safety functions as well as an integrated USB 2.0 peripheral supporting host, device and on-the-go (OTG) functionality.

This new device group brings the ultra low power features of the Renesas 8/16-bit RL78 MCU series to the 32-bit RX product lineup, offering a greater range of device scalability and functionality.
Key features include:

  • Flexible power management and optimum power consumption for all use cases, including three different run modes, three low power modes and a flexible clock system.
  • 32 MHz operating speeds and 1.56 Dhrystone MIPS (DMIPS)/MHz throughput, with power consumption as low as 64 uA/DMIPS.
  • Multiple communications peripherals support, including USB 2.0 host/function and battery charging, OTG, I2C, and SPI (serial peripheral interface) protocols.
  • Software compatibility with the RX600 and RX200 series MCUs, providing greater flexibility and an easy migration path to higher performance MCUs.

A starter kit is available with sample drivers, applications of high speed charging by USB, various middleware such as memory card, evaluation board with Renesas’ MCU and development environment required for MCU evaluation and first installation.
Samples of the RX111 devices should be available from July 2013, with mass production scheduled to begin in September 2013.
