Renesas Electronics has introduced the first in its RX100 Series of powerful 32-bit microcontrollers (MCUs) – the new RX111 Group. The RX111 is produced on an ultra low power zero wait state flash process supporting 32-bit power consumption / performance levels as well as supporting fast wake-up, and comes 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. The RX111 devices are designed to support a broad range of low-end 32-bit embedded applications including mobile healthcare, smart meters, sensors/detectors, and industrial and building automation.
Renesas’ True Low-Power capability offers designers the lowest possible power consumption across a vast range of temperatures and voltages, 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. :
Renesas’ ultra low power technology delivers flexible power management and optimum power consumption and the RX111 Group of MCUs is able to offer three different run modes, three low power modes and a flexible clock system.
The new devices feature 32 MHz 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.
The new devices support multiple communications peripherals, including USB 2.0 host/function and battery charging, OTG, I2C, and SPI (serial peripheral interface) protocols. Analogue functions include a 12-bit ADC (analogue-to-digital converter) with internal voltage reference, an 8-bit DAC (digital-to-analogue converter) and a temperature sensor.
Renesas is providing a Starter Kit (RSK) with sample drivers (mass storage class, communication class and HID class), 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.
The RX111 Group of MCUs is software compatible with the RX600 and RX200 Series, providing both 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 16 KB to 128 KB embedded flash memory with a roadmap to higher memory size. As part of the RX Family, the new MCUs also feature a compatible instruction set, hardware and software tools set, 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.
Renesas provides a comprehensive development ecosystem for the RX series, including a powerful Eclipse-based IDE, as well as compilers, debugger emulators, code generation and flash programmers and the new devices are also supported by IAR Systems’ EWRX tool chain compiler and IDE.
