See Release Information when using the E20 emulator.
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 equivalent to the E2 emulator Lite. It is capable of large-capacity tracing for enhanced debugging in combination with MCUs that incorporate trace output functionality.

Features
- Enhanced functions for faster debugging [Learn More :On-chip Debuggers Performance Property]
In addition to all the debugging functions of the E2 emulator Lite, 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). - Learn More

Additional Details
Specifications
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. The specific features of the E20 emulator such as the large trace function and the real-time RAM monitoring function are available only when using with MCUs of the RX600 or RX700 series. When using with MCUs of other than the RX600 or RX700 series, the supported functions for debugging correspond to those of the E2 emulator Lite.
Important : On the use of specific features of the E20 emulator
The signals used for the large trace and real-time RAM monitoring functions of the E20 emulator are multiplexed with those for other peripheral functions. Whether the large trace and real-time RAM monitoring functions of the E20 emulator are available depends on the MCU, package, and peripheral functions that you will be using.
We recommend that you read the user’s manual for the MCU you are using and check if there is any conflict of functions on the trace pins.
You can use the Smart Configurator to make pin settings through a GUI and check for conflicts between multiplexed functions.
If the MCU you are using is supported by a debug MCU board and you use the board, all of the MCU pins are available for use by the user system.

| Debug MCU Board for RX Family Supported devices for Debug MCU Board for RX Family [On-chip Debugger] (PDF | English, 日本語) 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. | lens |
