Cyclone for Renesas (Discontinued)

ISP Production Programmer for Renesas devices

NOTE: Cyclone for Renesas has been discontinued. PEmicro now supports Renesas devices via the Cyclone Universal FX with our Renesas adapterPlease visit the Legacy Hardware Transition Support Page for more information.

This blog post describes many of the new, more advanced features that are included with the Cyclone FX Universal. Current users of the legacy Cyclone for Renesas may also wish to take advantage of PEmicro's Cyclone Trade-In Program. It can provide a substantial discount when transitioning to the latest hardware.

Cyclone for Renesas (Legacy)
PEmicro's Cyclone for Renesas is an extremely flexible tool designed for in-circuit flash programming of Renesas R8C, RL78, RH850, RX600, M16C and M16C/80, M32C, H8 and H8S/Tinydevices.

By connecting to the debug header on the target, the Cyclone can program internal memory on a Renesas processor or external flash connected to the processor's address/data bus. The processor or memory device can be mounted on the final printed circuit board before programming.

The Cyclone may be operated through batch or dll commands from a PC. Once loaded with data by a PC it can be disconnected and operated manually in a completely stand-alone mode via the LCD menu and control buttons. The Cyclone has over 7Mbytes of non-volatile memory, which allows for the onboard storage of multiple programming images. When connected to a PC for programming or loading it can communicate via the ethernet, USB, or serial interfaces.

 Stand-alone Operation

One of the Cyclone's best features is its ability to work in a pre-configured, stand-alone mode. This ability is very useful for tasks like upgrading firmware in the field, or programming target boards on production lines. In this mode, the user pre-configures the Cyclone with an image that is to be programmed into the target hardware. Once the Cyclone is configured, the programming process may be initiated from the Host PC or by an operator in the field.

 PC Controlled Stand-alone Programming

In this mode, an image has already been programmed into the Cyclone. The PC launches the programming process with a simple command packet. Flash programming occurs directly from the Cyclone image to the target. The result is sent back to the host computer. As part of the command packet, dynamic data such as a serial number may be added to the fixed image being programmed into the target.

PC Control Of Multiple Cyclones

The Cyclone for Renesas includes the Basic Edition of PEmicro's  Classic Cyclone Automated Control Package. This allows the user to automate programming with one programming image on one Cyclone. PEmicro also offers enhanced editions of the control package which include features like:

  • Multiple Cyclone Control
  • Error Detection
  • Dynamic Data Programming
  • Image Maintenance

For more information about the Classic Cyclone Automated Control Package, please see the product page.  The beauty of this process is that multiple Cyclone units may be controlled at the same time.

User Control In Stand-Alone Mode

 User Controlled Stand-alone Programming

When detached from a PC, the Cyclone can still operate as a stand-alone programmer. The buttons are used to launch the programming process, and the LEDs display the status of the programming operation. This is ideal for short programming runs or for field updates, where having a PC may not be desirable.

* The Cyclone hardware supports multiple architectures and comes with flash programming software and configuration utilities for all such architectures.
