YRPBRL78L12 (For RL78/L12)

The Renesas Promotion Board is pre-programmed to work with the GUI provided on the included DVD to demonstrate the key low power capabilities of the RL78/L12 device family along with it's direct drive LCD functionality.
The RPBRL78L12 includes RL78/L12 CPU board with custom segment LCD integrated, On Chip Debugger (OCD), Eclipse based e2studio (a Integrated Development Environment), Free of charge GNU compiler and Example embedded code, extensive documentation.
This device family is also fully supported by our key development partner IAR Systems.


  • When you would like to start software development or MCU evaluation, please access to Design Support.


  • Easy to use device demonstration capabilities
    The YRPBRL78L12 contains elements to easily demonstrate simple I/O-functions (i.e. LED output, I/O lines, UART serial interface) together with the key functions such as Segment LCD driver, Real Time Clock (RTC), ADC, Timers, safety functions and on-chip data flash.
  • Power supply via USB interface
    The YRPBRL78L12 is powered via USB interface. No separate power supply is needed, although a connector is provided to supply an external power supply if required.
  • On-Board debug function
    The YRPBRL78L12 supports an On-Board debug function by using the supplied e2studio debugger, without the need of additional debug hardware. It allows Flash programming and supports standard debug functions such as code execution, single stepping, software breakpoints, memory manipulation etc.
  • Renesas Flash Programmer (RFP)
  • Windows based Flash programming software allows the user to select
    and download application programs to the YRPBRL78L12 board for evaluation purposes.
  • Applilet3 Device driver code generator
