Overview
Description
Topics
- The E2 emulator Lite supports the RA8P1 group, the industry's first ultra-high-performance microcontroller designed for AI, and the new device RA2T1.
- See Release Information when using the E2 emulator Lite.
The E2 emulator Lite (abbreviated as "E2 Lite") is an on-chip debugging emulator and flash programmer for MCUs of the RX, RA, RL78 families and RISC-V MCU.
The E2 Lite offers basic debugging facilities at a low price and is also usable for actual development. This emulator is suitable for various purposes, ranging from education and initial evaluation to professional development.
You can also use the E2 Lite with optional products for the E1 emulator (such as the hot-plug adapter).

Features
- Affordable yet powerful debugger functionality that meets actual development needs
Learn more about the on-chip debugger functionality - Optional products that will shorten your debugging periods
We offer various optional products including a hot-plug adapter, which can be used to connect the E2 Lite to a user system even while the system is running a program.
- Also usable as an on-board programmer
You can use the E2 Lite as an on-board programmer on completion of debugging. This will enable smoother evaluation of the MCU in stand-alone operation. - Supports serial, JTAG, and SWD communications interfaces
The E2 Lite can be connected to the MCU through a serial, JTAG, or SWD communications interface. - Learn More
