Renesas recommends three emulator models that support real-time debugging on the actual chip using the debugging functionality built into the Renesas MCU mounted in the user system. Each of them can be used as flash programmers. They range from an affordably priced model which is compared with full-spec emulators and is suitable for education, initial evaluation to more advanced models with functions to support full-scale development work.
