This solution is a high-function version of the R0K578L1CD000BR RL78/L1C HMI Solution Kit.


(1) System Demo close to the actual product is available.

  • Combination of HMI such as Touch switch, sensor input, LCD display, voice sound record and playback, etc.
  • Sensor application waking up MCU by a sensor input trigger.

⇒ Reducing the period for planning and specification developing

(2) Utilize this product as a reference for user's development.
Reducing the number of external components and peripheral IC and the dimension size of the PCB by integrated functions of "RX231" and "SAIC101".

  • RX231: Touch sensor IC and sound playback IC, USB I/F IC can be reduced.
  • SAIC101: The discreet components such as an operation amplifier and a resister can be reduced.

⇒ Reducing the development time and resource, a system cost

(3) Reducing software development period by utilizing sample software as the reference.
⇒ Reducing 20% of Software development period.

(4) The development of power saving and M2M application is ready.
Smart Analog IC automatic calibration by MCU is available.
⇒ Realizing sensor controlling system with high reliability.

  • Sample software

This software has developed by Firmware Integration Technology (FIT) module which Renesas developed and inherited FIT features. It is easy to develop user application program when user uses this software as the base program.


  • HMI Evaluation board
    • High power efficiency 32-bit MCU "RX231" built-in Capacitive Touch detection and USB Host I/F.
    • Smart Analog IC "SAIC101" for controlling 16-bit A/D Converters and the amplifier gain.
    • Capacitive Touch switch function
    • Voice memo function (with Speaker and Microphone)
    • LCD Panel (Character)
    • Pyroelectric infrared sensor, Acceleration sensor
    • USB Connector (Host/Function)
  • Battery box (Excluding AAA battery)
  • Release note (Users manual and Schematic diagram, Part list are ready to download from following URL)
  • Note: Demo software is programmed in Flash ROM for USB, LCD, Capacitive Touch, Voice Memo, Sensor control, Pedometer etc.
