Overview

The RX Adapter allows connections between J-Link or Flasher and target hardware which comes with the Renesas RX600 / 200 / 100 series MCUs. When using the RX Adapter, please make sure that you are using the latest revision of this adapter, since on older revisions specific features like FINE interface support may not be supported. The back-side of the adapter shows the revision of it. The current revision is 5. Older revisions may not show a revision on the back-side but a production date only. Please replace these adapters with one of revision 5 or newer.

The RX adapter is able to optionally power the connected target hardware. 3.3 V or 5 V supply voltage can be selected using a Jumper. The target is supplied via the VTref connection (pin 8) when the supply option is jumpered. The RX Adapter is shipped with option "do not power target" (jumper open)

Pinouts and Jumper Settings

JTAG Connection

RX Adapter Pinout — JTAG connection
RX Adapter Pinout — JTAG connection
Jumper (light red) setting – JTAG connection
Jumper (light red) setting – JTAG connection

The RX Adapter supports connecting via JTAG to the following cores:

  • RX610
  • RX621
  • RX62G
  • RX62N
  • RX62T
  • RX630
  • RX631
  • RX63N
  • RX63T
  • RX64M
  • RX65N
  • RX660
  • RX66T
  • RX671
  • RX71M
  • RX72N

FINE Connection

RX Adapter Pinout — FINE connection
RX Adapter Pinout — FINE connection
Jumper (light red) setting – FINE connection
Jumper (light red) setting – FINE connection

It can also be used for connecting via FINE to the following cores:

  • RX111
  • RX13T
  • RX140
  • RX210
  • RX21A
  • RX220

Please note:
For connecting to RX63x or RX72N devices via FINE, the RX FINE Adapter is required.

The FINED Signal: Since the FINE interface is a open-drain specified interface, there is always a pull-up necessary on the target hardware. Pull-up recommendation is 1k Ohm.
