MCUs combine low cost, ultra-low power, and 32-bit performance for IoT
Renesas Electronics Corporation's new RX110 Group of MCUs delivers a combination of ultra low-power consumption and high performance at attractive price points for entry-level 32-bit embedded Internet of Things (IoT) applications. A complement to the RX111 Group announced in April 2013, the new RX110 MCUs combine RX core performance along with Renesas’ True Low Power features, providing greater device scalability for cost-sensitive applications. The new RX110 devices offer superior active power/power-down mode capabilities, system performance, and DSP implementation levels for entry-level 32-bit MCUs.
RX110 MCUs enable extended life cycles for battery-powered applications with 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 new MCUs feature three operating speeds, achieving 1.56 Dhrystone MIPS (DMIPS)/MHz throughput and 3.08 CoreMark®/MHz. With the RX110 Group, Renesas offers the only entry-level 32-bit line to provide a complete DSP library, as well as single-cycle Multiple/Accumulate and hardware-based Divide capability.
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 32-bit 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
- Cyclic redundancy check (CRC) – a hardware-based feature that prevents timing or corruption issues with the communication functions
