E2 emulator Lite [RTE0T0002LKCE00000R]

The E2 emulator Lite (abbreviated as “E2 Lite”) is an on-chip debugging emulator and flash programmer for MCUs of the RX and RL78 families. The E2 Lite is more economical than the E1, and is suitable for work across the whole range from hobbyist projects and education to professional development.

System Configuration



Optional Products

Following devices are optionally provided to facilitate the use of the E2 emulator Lite.
Please make sure to choose the devices that match the type of your emulators and MCUs.




Note: Please read references to "E1 emulator" in the manuals for optional products as also meaning "E2 emulator Lite".


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

  • 14-Pin to 38-Pin Conversion Adapter for the E1 Emulator
  • R0E000010CKZ00
  • An adapter for converting the 14-pin/2.54-mm pitch connector on the head of the emulator user interface cable to a 38-pin/0.5-mm pitch connector
  • Small Connector Conversion Adapter for the E1 Emulator
  • R0E000010CKZ11
  • An adapter for converting the 14-pin/2.54-mm pitch connector on the head of the emulator user interface cable to a 14-pin/1.27-mm pitch connector


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

  • Hot-plug Adapter for the E1 Emulator
  • R0E000010ACB00
  • An adapter that allows connection of an emulator to a running user system without turning the power off
Note1 Note1

1: Refer to [On-chip Debuggers Performance Property] for the applicable MCU groups.


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

  • Isolator for the E1 Emulator
  • R0E000010ACB10
  • (For the RX or the R8C family)
  • Isolator for the E1 Emulator
  • R0E000010ACB20
  • (For the RL78 or the RH850 family)


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.

  • Low voltage OCD Board for RL78/G10 (10-pin/16-pin)
  • R0E510Y47LVB00
  • An OCD board for debugging an RL78/G10 MCU (10-pin or 16-pin) with an adapter voltage below 4.5 V
