  • Description
  • E1 emulator [R0E000010KCE00]


    New on-chip debugging emulators (Recommended for customers who are using or considering to purchase the E1):

    [For RX or RL78 Family MCU Users]
    E2 emulator Lite is available features equivalent to the E1 at a more affordable price. Learn More >>

    [For RH850, RX, or RL78 Family MCU Users]
    E2 emulator is available high-speed download up to twice as fast as the E1 and solutions to reduce development time. Learn More >>



    The E1 emulator is an on-chip debugging emulator and flash programmer which supports the major Renesas MCUs. This economical development tool provides basic debugging functionality. Available optional products, such as the hot-plug-in adaptor, allow you to extend debugging functionality or adjust connections.

    We will soon discontinue production of the E1 emulator due to components of the product having reached their EOL (end of life, i.e. end of production), so are now accepting final orders. Learn More (Tool News) >>

    Enhanced functions for faster debugging

    In addition to basic debugging functions, the E1 supports execution time measurement and hot plug-in functionality (dependent on the MCU) that allows connection to the user system while the program is running.

    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).


    Note that some functions shown here may not be supported under the IDE you use. Performance property and Connection system also vary depending on the MCU type.

    • Break function
    • Trace function
    • Memory reference and change while executing the program

    Optional Products

    Following optional products are provided to facilitate the use of the E1 emulators. Please make sure to choose the products that match MCUs you use.

    Conversion Adapter — Converts the number and pitch of the pins in the connector for the connection with the emulator.

    Hot-plug Adapter — Allows you to connect the emulator without having to turn off the system (Hot Plugin).

    Isolator — Enables debugging in an environment where there is a difference in potential between the user system GND and the host PC GND.

    Low voltage OCD Board — Enables you to debug the target MCU, even if the adapter voltage is not high enough to reprogram internal Flash ROM. This product is used between the emulator and a user's system, and is united by the in-circuit connection with the user's system.

    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.

    Target Devices

    RX Family

    RL78 Family

    RH850 Family
    Note: The E1 does not support RH850-family MCUs with the next-generation G4MH core, such as those of the RH850/E2x series. The E2 emulator is available for use with them.

    V850 Family

    78K Family

    R8C Family

    As the supported devices are different depending on the software you use, refer to the "Target devices" in Release information.
