E1 emulator [R0E000010KCE00]
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.
New on-chip debugging emulators - Recommended for customers who are considering to purchase the E1 or that users -
[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.

1: For details when using devices of V850 family, 78K0R, 78K0, or R8C family, see E1/E20 software for V850, 78K0R, 78K0, or R8C MCU >>.
2: As for tools produced by partners, contact them directly.
3: Debug support only (For building, use the IAR Embedded Workbench compiler made by IAR systems or the MULTI compiler made by Green Hills Software,Inc.)
- Affordable yet powerful debugging device that can meet the actual development needs.

- 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.

1: Refer to [On-chip Debuggers Performance Property] for the applicable MCU groups.
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.
Debug MCU Board for RH850 Supported devices for Debug MCU Board for RH850 Family [PDF]
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.
- 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.
As the supported devices are different depending on the software you use, refer to the "Target devices" in Release information.
