Renesas RL78

RL78 - True Low Power Microcontroller Platform

The RL78 Family of microcontrollers (MCUs) combines advanced low power technology, outstanding performance, and the broadest line-up in its class for the most demanding 8- and 16-bit embedded applications.

The RL78 MCUs‘ innovative “Snooze“ mode achieves ultra-low power by allowing ADC operation and serial communication, all while the CPU is turned off. This makes the RL78 MCUs best in class for low power applications.

Renesas Promotion Board for RL78/G13

 

The YRPBRL78G13 is a promotion board for the new Renesas RL78 microcontroller family. It supports on-board debugging, flash programming, and is pre-programmed to work with the GUI provided on the included DVD to demonstrate the low-power capabilities of the Renesas RL78 MCU.

Product Features

  • Easy to use device demonstration capabilities
    The YRPBRL78G13 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 Real Time Clock (RTC), ADC, Timers, safety functions and on-chip data flash.
  • Power supply via USB interface
    The YRPBRL78G13 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 YRPBRL78G13 supports an On-Board debug function by using the IAR CSPY 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.
  • WriteEZ5 Flash programming software (preliminary version)
    Windows based Flash programming software allows the user to select and download application programs to the YRPBRL78G13 board for evaluation purposes.
  • Applilet3 Device driver code generator
    Software tool used to generate device driver code to initialize and use on-chip peripherals (preliminary version)
  • Various input / output signals available, such as
    • All I/O ports prepared to be connected to user hardware
    • Virtual UART interface, via the μPD78F0730 78K0 8-bit microcontroller with on-board USB interface
    • 1 LED connected to a RL78/G13 port for visualization.
