Target Boards for Renesas RX 32-bit MCUs

Renesas Electronics has announced three new Target Boards for the RX65N, RX130 and RX231 Microcontroller (MCU) Groups, each designed to help engineers jump start their home appliance, building and industrial automation designs. Priced below $30, the Target Boards lower the price threshold for engagement, allowing more system developers to make use of Renesas’ broad-based 32-bit RX MCU family.

The RX Target Boards provide an inexpensive entry point for embedded designers to evaluate, prototype and develop their products. Each board kit features an on-chip debugger tool that enables application design without requiring further tool investments. Through-hole pin headers provide access to all MCU signals pins, making it easy for users to interconnect to standard breadboards for fast prototyping.

The RX Target Board evaluation concept reuses the same PCB for all MCU variations. Since each member of the Renesas RX MCU Family has a common pin assignment, users experience a smooth transition between different RX Groups and RX Series using the same package version. In the case of the RX Target Boards, the widely used 100-pin LQFP package is on board.

The RX Target Boards offer everything designers need to start board and demo development, including a board circuit diagram and bill of materials, demo source code, user manual, and application notes. Additional Target Board variations will be released soon that will provide full coverage of the entire RX Family, from the low-power RX100 Series to the high-performance RX700 Series.

The RX65N MCU Group combines an enhanced RX CPU core architecture and 120 MHz operation to achieve processing performance of 4.34 CoreMark/MHz. The MCUs include an integrated Trusted Secure IP, enhanced, trusted flash functionality, and a human-machine interface (HMI) for industrial and network control systems operating at the edge of the Industrial Internet of Things (IIoT). The RX65N MCUs also include an embedded TFT controller and integrated 2D graphic accelerator with advanced features ideal for TFT displays designed into IIoT edge devices or system control applications. In addition, the RX65N MCUs include embedded communication-processing peripherals such as Ethernet, USB, CAN, SD host/slave interface and quad SPI.

The RX130 MCU Group provides 32 MHz operation with flash memory sizes up to 512 KB, and package sizes up to 100-pins to provide higher performance and compatibility with the RX231/RX230 Group of touch MCUs. The ultra-low power, low-cost RX130 Group adds higher responsiveness and functionality for touch-based applications requiring 3V or 5V system control and low power consumption. Featuring a new capacitive touch IP with improved sensitivity and robustness, and a comprehensive device evaluation environment, the new 32-bit RX130 MCUs are an ideal fit for devices designed with challenging, non-traditional touch materials, or required to operate in wet or dirty environments, such as a kitchen, bath or factory floor.

The RX Target Boards are available now through Renesas Electronics’ worldwide distributors with a recommended resale price below $30.

Software Aids STM32 MCU System Development

STMicroelectronics has extended its STM32 software ecosystem with a Sigfox package that simplifies development and gives extra flexibility to connect Internet-of-Things (IoT) devices to long-range, low-power wireless networks. The new X-CUBE-SFOX package is ready to use with ST’s B-L072Z-LRWAN1 Discovery Kit, which is already LoRa enabled through I-CUBE-LRWAN embedded software. Developers can now work with either of these established Low-Power Wide Area Network (LPWAN) technologies on the same hardware, and create products that can use the two protocols individually or alternatively.

The Discovery Kit features the Murata CMWX1ZZABZ-091 module powered by an STM32L072 microcontroller, a sub-GHz radio transceiver SX1276 from Semtech, and is expandable via Arduino headers to add sensors or other IoT-device functions and capabilities. X-CUBE-SFOX contains a complete set of Sigfox libraries and application examples for the STM32L0, and can be ported to other microcontrollers in the STM32 family.

With over 700 STM32 variants, from ultra-low-power to high-performance lines, developers can leverage unrivaled flexibility to optimize the performance and features of IoT devices that take advantage of Sigfox services including basic connectivity, radio recognition, and GPS-free location. The software’s low memory footprint and efficient CPU utilization minimize demand for system resources, helping to lower bill-of-materials (BOM) costs and power consumption.

The X-CUBE-SFOX software can be downloaded free of charge from www.st.com/x-cube-sfox. The B-L072Z-LRWAN1 Discovery Kit is available now, priced $46.50.
