The J-Link RX Adapter allows JTAG connections between a Segger J-Link and target hardware which comes with the Renesas RX600 series MCUs, e.g. RX610 Group, RX62N Group, RX621 Group.
All that is needed to use J-Link with a Renesas RX600 series MCU is this RX Adapter. This adapter can be used with J-Link, J-Link Pro, J-Link Ultra+, J-Link EDU and any other licensed J-Link compatible emulator. The required software can be downloaded from Segger's website and used free of charge.
J-Link with RX Adapter Features Note: This product is the adapter only. The following feature list is meant to give you an idea of what you can do with the adapter when connected to one of the J-Link programmer/debuggers listed above.

J-Link vs. Renesas E1. What are the advantages of J-Link?
- Higher speed
J-Link achieves (at the time of writing, using the current versions of both the J-Link and E1 software) a speed of approximately 2-6 times the speed of the E1. This is true for basically all operations, including download to flash, setting of breakpoints in flash as well as startup and typical debugging operations like single-stepping or memory-read operations.
- Smart breakpoint management
Flash breakpoints are much faster on J-Link than on E1 or E20, but because of the large flash sectors of up to 128KB, setting or removing flash breakpoints is still time consuming. J-Link uses different techniques to minimize the amount of times a flash breakpoint is set or removed. Some of these techniques are: Instruction set simulation, use of hardware breakpoints where possible, dynamic conversion of breakpoint types, flash caching, CRC checking and others.
- SDK available
You can write your own application and control an RX600 series MCU using J-Link.
- Same probe for ARM and RX600 CPUs
No need to switch emulators!
- Control panel allows monitoring of operation
- 64-bit OS supported
- J-Link commander: Free command-line utility for J-Link
- J-Flash software allows using J-Link for production purposes
