JP214/RTK-251-SinkAdapter Instruction Manual
Introduction
The JP214 / RTK-251-SinkAdapter is an evaluation board for Universal Serial Bus Power Delivery (USB
PD). The RTK-251-SinkAdapter is designed with USB PD controller R9A02G011 and Buck-Boost Voltage
Regulator (BB-VR) ISL95338 (substitute product: RAA489800). This document is the instruction manual for
RTK-251-SinkAdapter.
The RTK-251-SinkAdapter supports USB PD 2.0, USB PD 3.1, USB Type-C®Specification. The RTK-251-
SinkAdapter works as USB Type-C®power sink, it converts USB-C input power supplied by Type-C sourcing
device to DC output. Because there are several losses on the cable, BB-VR, and board, USB PD controller
compensates the USB-C input level to achieve the expected DC output. For example, When Type-C
sourcing device supplies up to 20V@5A, RTK-251-SinkAdapter can provide up to 20V@4A to DC output
with these losses. The board also has an operating mode that feed USB-C input directly to the DC output.
Switches connected to the USB PD controller R9A02G011 allows selection of DC output voltage/current and
operating mode.

Because there are losses on cable, BB-VR and also path on board, if

The code flash memory can be rewritten to through serial programming using a flash memory programmer.
The following dedicated flash memory programmers can be used to write data to the flash memory of the
R9A02G011. For details, refer to the related documents of the tools.
- PG-FP6
- E1, E2, E2 Lite, E20 on-chip debugging emulator
Data can be written to the flash memory on-board by using a dedicated flash memory programmer. The

The contents of the flash memory can be rewritten after the R9A02G011 have been mounted on the target
system. The connectors that the dedicated flash memory programmer uses must be mounted on the target
system.
Please use Renesas Flash Programmer V3 as programming software. Refer to the following documents.
Renesas Flash Programmer V3.12 Flash memory programming software User’s Manual (R20UT5312EJ)
List of MCUs supported by Renesas Flash Programmer V3 (R20UT3599EJ)
On the development of flash memory programmer by user, refer to RL78 microcontrollers (RL78
Protocol A) Programmer Edition Application Note (R01AN0815EJ).
Flash programing for R9A02G011 is compatible with the RL78 MCU series. Therefore, if user want to use
available flash memory programmer that supports RL78 MCU, we may be able to port the library for that
programmer. Please ask a contact window.

3.3.3 FW writing with Renesas on-chip debugging emulator
User can write(load) firmware by Renesas on-chip debugging emulator. Since RTK-251-SinkAdapter does
not have full 14 pin connector for the emulator, User shall connect via a converter which is made with the
bundled cable when using Renesas on-chip debugging emulator.
1. Connect conversion connector to CN2 on the board.
2. Connect Renesas on-chip debugging emulator to conversion connector.
3. Connect the emulator to USB port of the PC.
