RL78 14-Pin Programming Adapter

The RL78 14-Pin Programming Adapter converts the standard 20-pin 0.1" connector to the standard 14-pin E1 connector defined by Renesas. The 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 VT_REF connection when the supply option is jumpered.

Please note that this adapter is usable only for the purpose of flash programming. It cannot be used with a J-Link and it cannot be used for debugging RL78 devices.

The TOOL0 pins of the RL78 devices are open drain and require an external pull-up resistor. This resistor is usually placed on the evaluation board, nevertheless the adapter has an additional solder bridge between VT_REF and TOOL0 to place the pull-up resistor.
