Flash Support Group's in-circuit programmers make it possible to program flash memories and flash microcontrollers already mounted in the user systems. They can be used in various locations from design and development to mass production and maintenance.

AF9101/03 In-Circuit Serial Programmer

These products were discontinued at the end of May 2019.
>> Notice of discontinuation of AF9101/AF9103
Device support in software will continue.

Universal in-circuit programmer which is adaptable to any programming environment


  • Wide device support
    It supports flash microcontrollers and various flash memories.
  • Use of specialized memory card
    The control of master and operations can easily be done by the specialized algorithm memory card (CF card) which saves the programming algorithm, setting parameters, programming data, and verify data.
  • High speed transfer of programming data
    High speed data transfer from a PC is possible by the USB interface.
  • Operated by remote control
    It can be operated and controlled easily from your PC.



  • Used as stand alone
    It can be operated independently without PC by the stand alone function.

  • Provides free update of algorithm software
    The latest version of algorithm software is available on our website for free download.*However, the updating is limited to the devices which you selected at the time of initial setting. * User registration is required to use our download service.

  • Gang programming to multiple circuit board
    Using the dedicated external control interface, it will be possible to input actions according to an external trigger signal and to output results externally. The operability and productivity will be increased by incorporating several programmer main units.
