Fujitsu Microelectronics Europe, a world-leading semiconductor supplier and UNIS, an embedded systems development tools vendor, recently introduced a high-speed, in-system programming solution for all Fujitsu flash microcontroller families.
Fujitsu's flash-based microcontrollers are highly successful with today's massive demand for reliable devices featuring in-built rewritable memory. The rewritable memory function offers a big advantage due to the frequent need for changing programs at each stage of development, evaluation and mass-production, and also because of slight changes in software specifications for each type of equipment. Since the guaranteed number of erase cycles for all Fujitsu flash microcontrollers is well over the 10 000 range, these devices are also very well suited in cases when the application requires nonvolatile storage for data acquired during application run-time.
To make flash programming as easy as possible, Fujitsu's programming solution - called the flash-kit programmer - allows in-system programming of target CPUs. This means that no additional hardware is needed for programming on user target boards. In comparison with the old RS232 based in-system programming utilities, the flash-kit programmer also greatly reduces programming time by exploiting the synchronous serial programming mode of Fujitsu CPUs, which enables transfer of user data at speeds of up to 500 Kbps.
The flash-kit programmer consists of an MS Windows 9x/NT/2000 compatible PC software front-end and a small programming box, which is needed for high-speed synchronous programming. This box can communicate with the PC via serial or parallel ports. Moreover, the PC software front-end can also be used without the box in asynchronous serial programming mode.
Additional features of the flash-kit include:
* Supported CPUs: 8L family, 16LX family and FR families.
* The box firmware can be easily updated using the PC serial port.
* Programming box can provide supply to the target system.
* Dimensions of programming box is 126 x 90 x 22 mm.
