EK-RX671

The EK-RX671 is the evaluation kit for the RX671 MCU, providing an efficient tool to evaluate the RX671 MCU. This kit comes with all the hardware and software needed to start evaluation immediately after unboxing.

The EK-RX671 enables debugging key functions of the RX671. In addition, it could be combined with various expansion boards quickly to easily expand the board's functionality.

This board features:

• Hardware and software ready for evaluation right out of the box
  • On-board debugger (E2 OB): program writing and debugging are possible simply by connecting the board to a PC via USB cable.
  • Ready-to-use software package includes peripheral function drivers, middleware, and guidance documentation.
• Ability to develop prototypes for a wide range of requirements.
  • On-board popular ecosystem connectors: easily integrate with expansion boards such as sensor, wireless, LCD, motor boards, etc, enabling to develop wide range of application quickly.
  • On-board HMI application target function: 2 capacitive touch buttons, Audio Interface with MEMS micros and 3.5mm headphone jack enable to evaluate HMI functions
  • Rich external memory expansion function: 64Mb QSPI Flash, 128Mb 16-bit SDRAM, MicroSD Slot enable expanding memory easily
  • Multiple power options to enhance power supply flexibility to meet various needs.

Getting Started

Developing Embedded Application

The software development to evaluate RX671 MCU’s function could be started immediately using the e² studio IDE and the RX software package that includes peripheral function drivers, middleware, and usage documentation.

1. Get familiar with EK-RX671 through the Quick Start example project –The Quick Start example project shows:
   • Communication between EK-RX671 and Host PC through USB to Serial interface
   • Control User LEDs via User Buttons
   • Quad-SPI Flash Read/Write Operation via QSPI
   Refer to the EK-RX671 Quick Start Guide for details.
2. Start with one of the application projects – Choose from application projects to learn about the different peripherals of the RX671 MCU Group. The number of projects will grow progressively over time. These example projects can be downloaded from “Design & Development” and serve as excellent starting points for you to develop your custom applications.
   • Audio Output/Input project via Serial Sound Interface (SSIE)
   • HMI application project demonstrating SPI LCD display and Cap Touch functions.

Building a Custom Hardware

1. Start by building a functional prototype – Utilize the EK-RX671 board with your choice of hundreds of popular ecosystem add-ons.
2. Build custom hardware – Develop custom hardware by referring to the design and manufacturing information provided in the EK-RX671 Design Package.
