OpenFOTA, ABUP's Over-the-Air (OTA) delta solution for Renesas RA 32-bit microcontrollers (MCUs), brings together experience from serving many IoT applications. It aims to upgrade the MCU memory with the help of the delta upgrade capability of modules and Flash resources, so that the main control program can achieve OTA function more easily and conveniently. OpenFOTA provides an integrated solution to the OTA upgrade of the whole system. It can upgrade not only modules but also main controls.



  • More efficient delta algorithm: Reduce download and program, reduce power consumption; high security, short interruption
  • Maximize the resource utilization: Make full use of the memory resources
  • High reliable protection mechanism: Provide mechanisms such as failback and security authentication, Support rollback without consuming MCU resources
  • Codeless OTA capability: No need to develop, can use after program
  • Multiple OTA scenarios: Support multi-mode OTA delta upgrade, such as NB-IoT plus Infrared
