As a sophisticated on-chip debugging emulator and flash programmer, the E20 emulator provides enhanced trace functions and RAM monitoring functions for RX600 and RX700 products, and the full basic debugging functionality of the E1 emulator. It is capable of large-capacity tracing for enhanced debugging in combination with MCUs that incorporate trace output functionality.

Topics

Features

  • Enhanced functions for faster debugging [Learn More :On-chip Debuggers Performance Property]
    In addition to all the debugging functions of the E1, the E20 supports powerful functionality such as larger trace capacity and realtime RAM monitoring. In addition, coverage function is supported on some MCUs of RX64M and RX71M Group.。
  • Also functions as an on-board programmer.
    Can be used as an on-board programming tool after the debugging, enabling smooth evaluation of the MCU.
  • Optimally suited for evaluating analogue functions such as A/D and D/A properties.
    Electrical characteristics are the same as those of the actual MCU, since the actual MCU is used for debugging.
  • Serial, JTAG and LPD connections are supported.
    For the communication system, serial, JTAG or LPD connection can be selected as required by the type of the target MCU.
  • Simple connection
    Connection requires only a connector mounted on the user system, thus significantly reducing the possibility of loose connection.
  • Environmentally friendly material
    The casing is made of plant-derived polylactide (PLA).

Debug MCU Board

Enables the incircuit connection of the emulator with the user's system. This board allows you to use enhanced debugging functions. The applicable debugging function varies depending on the MCU type.

Supported devices for Debug MCU Board for RH850 Family [On-chip Debugger] (PDF | English, 日本語)
This board enables use of the trace function even if the target MCU does not have a trace function. The Debug MCU Board is for use in combination with a separately available 176-pin (with internal trace function) MCU of the RH850/F1L group.

Note: The package of the Debug MCU Board does not include the MCU. Please purchase it separately. For details, contact either a Renesas Electronics Corporation representative (responsible for sales) or distributor.

This board enables the use of all user port pins of the MCU in the user system. The E20 emulator occupies some of the pins for control of the emulator and the output of trace information, and these pins must be connected with a 38-pin connector attached to the E20 emulator on the user system. However, the Debug MCU board enables the use of all user port pins because connection with a 38-pin connector on the user system is not required.
You can also obtain trace information even while using an MCU that does not have a trace function.
