Description

The E8a on-chip debugging 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 debugger 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 debugging 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, debugger support software for the E8a and evaluation versions of the Renesas compiler toolchains. Supported versions of the toolchains are available from your Renesas supplier.

Features

  • Ultra-compact dimensions:92 mm × 42 mm × 15 mm
  • Biodegradable material : E8a's plastic case is made from a biodegradable material. (a vegetable-based polylactide [PLA])
  • Complete debug functions
  • Real-time emulation possible even at highest CPU operating frequency. Ample built-in Break and Trace functions for Tiny MCU System developments.
  • Memory expansion mode is supported. (Device Permitting)
  • See Specifications for further details.
  • Close to target system actual evaluation
  • The user system can be debugged in conditions as close as possible to the end-product.
  • Superior capabilities : The debugger ensures high-efficiency debugging 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 debugger 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.

Application Note PDF 862 KB
AI-generated Summary: The Start/Stop feature allows execution of specified routines immediately before a user program starts and after it stops, enabling safe debugging in applications like motor control by stopping or restarting processes accordingly. The feature supports time measurement of program execution. Start/Stop routines must end with RTS, avoid altering certain registers, and follow specific precautions to maintain emulator control. It is compatible with several Renesas microcomputers but has limitations on some models.
Application Note PDF 2.62 MB
AI-generated Summary: The E8a emulator operates in two modes: debug and writer. In writer mode, it programs only the user program into the microcomputer’s internal flash memory, allowing the program to run independently without the emulator. The document details software installation, including the High-performance Embedded Workshop and compiler packages, and explains procedures for writing data, setting ID codes, and verifying program behavior. The ID code check facility secures the flash memory by restricting read and erase operations without the correct code.
Application Note PDF 2.69 MB
AI-generated Summary: This document provides important notes regarding the use of Renesas products, emphasizing that the information is for reference only and subject to change. It disclaims warranties and liabilities, restricts military and life-critical applications, and advises users to confirm the latest product data. Safety measures and compliance with export laws are highlighted. Renesas products require careful evaluation for suitability in specific applications, especially those demanding high reliability and safety.

Functions

On-chip Debugging Features

  • Used as an on-chip debugger, 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 debugger 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 debugging.
  • E8a product is ready for system development and debugging 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 debugging 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 debugging 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.
