[Upgrade to Revision]RL78 Family Renesas Flash Driver RL78 Type 01 SC Version V1.20 (PDF | English, 日本語)

The code flash library is free-of-charge software that reprograms the contents of the code flash memory by user programs.
"Renesas Flash Driver for RL78" is free-of-charge software that reprograms the contents of code flash memory and data flash memory by user programs.

Features

  • Flash Self Programming Libraries provide the interface for operations on the code areas of flash memories that MCUs have. (Functions are supported varies with the MCU. Please check the available functions in the user's manual for the target flash reprogramming software.) :
    • Erasing
    • Programming
    • Internal verification
    • Blank checking
    • Security settings, etc.
  • An EEPROM emulation library for code flash memory is also included.

Notes:

  1. For the EEPROM emulation library, contact your local Renesas Electronics marketing office or distributor.
  2. In the User's Manual (Hardware) for some RL78 MCUs or the User's Manual for some Flash Libraries for the RL78 family, the self RAM areas used in common for all flash libraries may be shown. However, for the latest information, please refer to the RL78 Family Self RAM list of Flash Self Programming Library Rev.3.05 (PDF | English, 日本語).
  3. As the self RAM areas are used as the work area for the library, using these areas for the user program is prohibited. For the latest information, please refer to the RL78 Family Self RAM list of Flash Self Programming Library Rev.3.05 (PDF | English, 日本語).
