The E8a on-chip deb ing emulator is a development of the E8, maintaining the same functionality and ease of use whilst reducing both cost to the end user and the size of the unit.

The E8a is designed to be used both as an on-chip deb er for R8C Family, M16C Family, H8 Family H8/Tiny and Super Low Power Series, and 740 Family in conjunction with Renesas High-performance Embedded workshop, providing the user with a range of deb ing features as well as a handy device programmer. E8a is ideal for the modern development and prototyping environment with programming support for devices from all the main MCU families.

The product is supplied with USB host interface cable, a user interface cable, the E8a itself and a software pack containing High-performance Embedded Workshop, Flash Development Toolkit, deb er support software for the E8a and evaluation versions of the Renesas compiler toolchains. Supported versions of the toolchains are available from your Renesas supplier.

• See Specifications for further details.

Close to target system actual evaluation

The user system can be deb ed in conditions as close as possible to the end-product.

Superior capabilities

The deb er ensures high-efficiency deb ing with a dedicated window for setting Break-points and Break conditions, trace data window display and command line functions. High-speed downloading of a load-module file also supported.

High-performance Embedded Workshop (Renesas IDE) offers seamless support for system development

The High-performance Embedded Workshop IDE brings the deb er component, compiler toolchain and some FLASH programming capability together within a single application environment, there is no need to keep launching different applications - the IDE takes care of it all.

USB bus-powered: no external power supply required

The host PC supplies power to the E8a via the USB bus meaning no external power supply is necessary. Use it anywhere, anytime. Power can also be supplied on to the user system from the E8a emulator.

On-board programming

The E8a can be used as a FLASH memory programming interface in conjunction with the Flash Development Toolkit.

E7/E8 compatibility means smooth environment migration

No special adjustments are necessary to connect to any system designed to connect to the predecessor E8 or ancestor E7 debug modules, the E8a will slot directly into such designs, an example of this is the Renesas Starter Kits (RSK) which will work just as well with E8a as with an E8.

Functions

On-chip Deb ing Features

• Used as an on-chip deb er, the E8a utilizes the on-chip functions built into the device and allows the user　to perform complete system debug, from MCU operations to electrical characteristics.
• The Renesas integrated development environment "High-performance Embedded Workshop" provides the user with a common GUI front end, it supports both the deb er functionality of E8a and a variety of development software tools, such as the C compiler and simulators. The result is a seamless toolchain enabling highly efficient program development from coding to building and deb ing.
• E8a product is ready for system development and deb ing the minute it reaches the user, the software package includes evaluation versions of cross tools for immediate connection and all necessary cables to enable connection to the target system are included.

Flash Memory Programming Features

• The E8a supports flash memory programming of the　Renesas　microcontrollers using the Flash Development Toolkit, enabling the user to program the devices using the E8a as a hardware interface.
• The High-performance Embedded Workshop includes a function that allows quick programming of the flash memory in the R8C, M16C, and H8 family microcontrollers; this can be useful when building and deb ing code.

START/STOP Function

• This emulator has the START/STOP function so that it is available to execute the designated routine of the user's program, immediately before starting the user's program execution or immediately after stopping the execution. Therefore you can interrupt the function you would like to halt during deb ing and also resume it.

  

How to program

• The following two programming methods are available.
  • Using the Flash Development Toolkit (Flash programming tool for Renesas flash memories)
  • Using the "Writing Flash Memory" mode of the E8a emulator
    Supported MCUs are the same as those enable on-chip debug features.
