Overview

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 of the E1 emulator. 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
In addition to all the debugging functions of the E1, the E20 supports powerful functionality such as larger trace capacity and realtime RAM monitoring. In addition, coverage function is supported on RX64M or RX71M Group.
Learn more about debugging functions (On-chip Debuggers Performance Property) >>
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).

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 monitor 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 E1 emulator.

Note

  1. 1. The isolator is not usable in combination with the debug MCU board for the RX71M group.
  MCUs
RH850
Debug MCU Board for RH850   Supported devices for Debug MCU Board for RH850 Family
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.

Note: The package of the Debug MCU Board does not include the MCU. Please purchase it separately. For details, contact either a Renesas Electronics Corporation representative (responsible for sales) or distributor. (Buy or Sample)>>

System configuration

  MCUs
RX
Debug MCU Board for RX Family   Supported devices for Debug MCU Board for RX Family
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.
