Renesas Electronics Introduces Industry’s First 32-Bit Microcontrollers with True Low Power and USB Connectivity

RX111 Devices Deliver Key Features Optimized for Emerging Mobile Healthcare, Smart Grid/Smart Home and Internet-of-Things Applications

SANTA CLARA, Calif.--()--Renesas Electronics Corporation (TSE: 6723), a premier provider of advanced semiconductor solutions, has introduced the first in its RX100 Series of microcontrollers (MCUs) – the RX111 Group, which is the market’s first 32-bit MCU to feature True Low Power™ as well as fast wake up, zero wait state flash, multiple safety functions and integrated USB 2.0 host, device and on-the-go (OTG) support. The new device group extends the True Low Power™ features of the Renesas 8/16-bit RL78 MCU Series to the 32-bit product line up, offering greater device scalability. Designed to support a broad range of markets, the new RX111 devices deliver a combination of ultra low power consumption, on-chip connectivity and superior performance at attractive price points for low-end 32-bit embedded applications including mobile healthcare, smart meters, sensors/detectors, and industrial and building automation.

“Leveraging Renesas’ proven process technology enables our RX100 Series to achieve a leading position in these areas, bringing True Low Power to the 32-bit world, and providing state-of-the-art communications, flexible power management and miniaturization to support these growing ´Smart Society´ needs.”

“Designing for ultra low power, connectivity and robust performance is essential as more applications, such as mobile health and smart energy, move toward a smaller energy footprint,” said Peter Carbone, Vice President of Marketing, Renesas Electronics America. “Leveraging Renesas’ proven process technology enables our RX100 Series to achieve a leading position in these areas, bringing True Low Power to the 32-bit world, and providing state-of-the-art communications, flexible power management and miniaturization to support these growing ´Smart Society´ needs.”

Renesas’ True Low Power capability offers designers the lowest possible power consumption across the entire temperature and voltage range, including all peripherals and Flash memory, while also providing maximum flexibility with multiple operational and sleep modes. This allows for the lowest possible power consumption for the user’s application environment.

IAR Systems provides support for the RX111 devices in the IAR Embedded Workbench for Renesas RX compiler and integrated development environment (IDE). And, as part of an exclusive agreement with Renesas, IAR Systems will also provide the 64KB free version of its Embedded Workbench for Renesas RX tools to support all RX devices, including the new RX111 MCUs.

“Performance and efficiency are key factors for embedded developers, and we have strengthened our partnership with industry-leading Renesas Electronics to continue supplying developers with the highest performing tools,” said Stefan Skarin, CEO IAR Systems. “As the only third-party tools provider covering the entire range of Renesas’ 8-, 16- and 32-bit MCU families, IAR Systems is proud to announce full support for the RX111 devices in IAR Embedded Workbench. The high performance scores achieved on the CoreMark benchmarks confirms IAR Embedded Workbench and the RX100 series as a great choice for customers aiming to create true low-power, high-performance applications. To give developers an opportunity to try this powerful combination, we also provide a free 64KB-limited version of the tools.”

With the addition of the RX111 group, the Renesas RX Family offers embedded designers one of the most comprehensive 32-bit line up that supports a wide range of applications, from the smallest, battery-powered equipment in which cost is the most important factor to the highest performance applications that require extensive data processing and computation.

About the RX100 Series

Based on Renesas’ RX CPU core, the RX100 Series of MCUs delivers high performance, ultra low power, connectivity and digital signal processing (DSP) functionality in a general-purpose MCU. The new RX111 devices feature 32MHz operating speeds and 1.56 Dhrystone MIPS (DMIPS)/MHz throughput, with power consumption as low as 64 uA/DMIPS. The MCUs also achieve 3.08 CoreMark/MHz and 14.9 CoreMark/mA.

Renesas True Low Power technology delivers flexible power management and optimum power consumption for all use cases. The RX111 group of MCUs offers three different run modes, three low power modes and a flexible clock system. For instance, the Low Power Fast Wakeup capability enables the MCUs to operate at 100uA/MHz in Run Mode and 350nA in Software standby from which it can wake-up in only 4.8us. It integrates a Zero Wait State Flash with Erase/Write as low as 1.8V, 1KB erase block size and background operation (BGO), and offer erase times as low as 10ms per block. The devices support multiple communications peripherals, including USB 2.0 host with battery charging, device and OTG, and the I2C, and SPI (serial peripheral interface) protocols. Analog functions include a 12-bit ADC (analog-to-digital converter) with internal voltage reference, an 8-bit DAC (digital-to-analog converter) and a temperature sensor.

The RX111 group of MCUs is software compatible with the RX600 and RX200 Series, providing greater flexibility and an easy migration path to higher performance MCUs. The Rx111 MCUs are available in low pin counts ranging from 36 to 64 pins and 16KB to 128 KB embedded flash memory with roadmap to higher memory size. As part of the RX Family, the new MCUs also feature compatible instruction set, hardware and software toolset, peripherals, and hardware safety features to comply with safety standards, including Cyclic Redundancy Checks (CRCs), Clock Accuracy Circuit (CAC), independent watch dog timer, a motor control timer (MTU2) and I/O ports.

Development Ecosystem

Renesas provides a comprehensive development ecosystem for the RX Family, including e2studio, a powerful Eclipse-based IDE, as well as compilers, debuggers, code generation tools and flash programmers. The RX111 devices are supported by the IAR Embedded Workbench for Renesas RX compiler and IDE. IAR Systems will provide the 64KB free version of these tools to support all RX devices, including the new RX111 MCUs.
