RX Adapter
Seamless connectivity for J-Link and Flasher
- Support for all Renesas RX series
- FINE and JTAG interface support
- Selectable target power supply
Overview
The RX Adapter connects J-Link debug probes or Flasher in-system programmers to target hardware based on Renesas RX series MCUs. It supports both FINE and JTAG interfaces, replacing the previous RX Adapter and RX FINE Adapter with a single solution. It is fully backward compatible with earlier RX Adapter revisions.
The adapter can optionally supply the target hardware with 3.3 V or 5 V, selectable via jumper. By default, the target power supply is disabled.
Jumper settings
The RX Adapter supports both FINE and JTAG interfaces. The interfaces is selected using two jumpers. Both jumpers must always be set to the same position.
FINE connection
Set both jumpers to position 2–3.
JTAG connection
Set both jumpers to position 1–2.
Target power supply
The target supply voltage can be selected using the third jumper:
- Position 1–2: 5 V
- Position 2–3: 3.3 V
- Open: No voltage supplied (default)
Pinouts
The following diagrams show the 14-pin connector pin assignments for FINE and JTAG connections.
