E8 (Discontinued product)
E8 emulator has been discontinued. The successor to E8 emulator is E8a emulator.
Target Devices
The E8 emulator is an on-chip debugger and is a flash memory programmer also. Supported MCUs differ depends on which way the E8 emulator is used in. See a matrix below.

Notes that flash memory quick programming at the Flash Momory Writing mode included in E8 emulator is available for the M16C and H8 family microcomputers that support the on-chip debug functions in the matrix above.
Overview
Reasonably priced and packed with special features, E8 products fully support speedy market-entry for the low-cost R8C/Tiny System products. Not only sophisticated various debug features, E8 offers flash momory programming features.

Debugging as Emulator

Programming as Programmer

| E8 emulator offers an on-chip debugger using the High-performance Embedded Workshop based graphical interface. The user system can be debugged in almost the same state as in actual final product operations by the various debug functions. For further information, see [1] Debugging Features.  High-performance Embedded Workshop graphic interface |
E8 emulator offers two ways of flash memory programming. One is by using Flash Development Toolkit, a flash programming software tool for Renesas flash memories. The other is by using the Flash Program mode of which the E8 includes. For further information, see [2] Flash Memory Programming Features.  Flash Development Toolkit graphic interface |
The E8 is a compact, smart debugging environment package for Renesas general purpose MCUs including the Tiny series.
The E8 emulator communicates with the R8C/Tiny MCU (except R8C/10-13) using only one pin (*1), a dedicated pin for debugging purposes only (not used for user system). E8 allows the user to perform complete system debug, from MCU operations to electrical characteristics, in a state close to actual operations of the final product.
The emulator is controlled via the emulator debugger (interface software) on the PC. The Renesas integrated development environment "High-performance Embedded Workshop" provides smooth links between the emulator debugger and a variety of development software tools, such as the C compiler and simulators. The result is the creation of a seamless tool chain enabling highly efficient program development through integrated interfaces, from coding to building and debugging.
E8 product packages are ready for system development and debugging the minute they reach the user, bundling cross tools for immediate connection and all necessary cables to the target system.
*1. When your target device is not R8C/Tiny (except R8C/10-13), for debugging, you use several pins that can be used for the user system. For details, refer to the E8 User's Manual Additional Document (Notes on Connecting MCUs that you are using) on the Documentation site.
[2] Flash Memory Programming Features
The E8 is also a flash programmer designed to support Renesas flash memory programming.
The Flash Program mode is an E8-included quick programming function using the High-performance Embedded Workshop based graphical interface. This mode allows quick programming of the built-in flash memory in the M16C and H8 family microcomputers even after program debug has been completed.
The E8 also supports flash memory programming of the M16C and 740(QzROM) family microcomputers using the Flash Development Toolkit, a flash programming software tool for Renesas flash memories. The Flash Development Toolkit enables serial communication to these microcomputers via the E8. See more...
