Renesas Electronics Corp. has included another device to its line of 32bit RX100 MCUs with the introduction of the RX110 Group. The MCUs claim to deliver a combination of ultra low-power consumption and high performance at attractive price points for entry-level 32bit embedded Internet of Things (IoT) applications such as mobile healthcare, environmental sensors/detectors, smart appliances, and industrial and building automation, detailed the firm.

The RX110 MCUs combine RX core performance along with Renesas' True Low Power features, providing greater device scalability for these cost-sensitive applications, added Renesas. Based on the firm's RX CPU core, the RX100 Series promises to deliver high performance, ultra low power, connectivity and digital signal processing (DSP) functionality in a general-purpose MCU. The RX110 devices offer the industry's best active power/power-down mode capabilities, system performance and DSP implementation levels for entry-level 32bit MCUs, added the firm.

With best-in-class run-mode power consumption, as low as 100µa/MHz, 4.8µs wake-up time and three low-power modes, including the lowest power-down mode with real time clock (RTC), the RX110 MCUs enable extended life cycles for battery-powered applications such as blood glucose meters, remote control systems or POS terminals.

The MCUs also feature three operating speeds, achieving 1.56 Dhrystone MIPS (DMIPS)/MHz throughput and 3.08 CoreMark/MHz. In addition, with the RX110 Group, Renesas claims to offer the only entry-level 32bit line to provide a complete DSP library, as well as single-cycle multiple/accumulate and hardware-based divide capability. This provides much-needed support for customers working in audio processing and digital filtering, as well as sensor-based applications.

To address critical compliance regulations, such as FDA/FCC certification and IEC60730 for enhanced safety, the RX100 Series, including the RX110 Group, features several safety and security functions and peripherals not available on any other entry-level 32bit MCU including on-chip clock frequency accuracy measurement circuit (CAC), which ensures the accuracy of the MCU's clock frequency; data operation circuit (DOC), which allows for hardware-based RAM memory testing that is used to identify a potential memory fault; and cyclic redundancy check (CRC), a hardware-based feature that prevents timing or corruption issues with the communication functions, noted Renesas.

The RX110 devices are supported by Renesas' development tools ecosystem. This includes the Renesas Eclipse-based e2 studio IDE and the Renesas RX compiler, IAR Systems' Embedded Workbench, as well as the RTOS kernels by Micrium, Segger, CMX, Express Logic, RoweBots and FreeRTOS. The recently launched RX111 Promotion Board (RPB) provides a unique and cost-effective evaluation platform designed to facilitate the evaluation of Renesas' RX100 MCUs.

Samples of the RX110 devices are available with mass production scheduled for March 2014 and expected to reach a scale of 1,000,000 units per month in December 2015. Pricing ranges from $0.95 for a 8KB, 36-pin configuration in 10,000-unit quantities to $1.51 for a 128KB flash, 64-pin configuration in 10,000-unit quantities. (Pricing and availability are subject to change without notice.)
