Description
The Renesas WP15WBD-RK Evaluation Kit demonstrates 15W
wireless power transfer and bi-directional data communication
between a transmitter (Tx) board with the Renesas P9242-R3
Wireless Power Transmitter IC and a receiver (Rx) board with the
Renesas P9221-R3 Wireless Power Receiver IC. The bi-directional
data communication channel enables users to authenticate a
wirelessly charged receiver device with a specific charging
transmitter base or to transfer system data without any additional
hardware.
This evaluation kit adds bi-directional communication to Renesas’
standard, WPC 1.2-compliant, 15W transmitter P9242-R and
receiver P9221-R evaluation kits without compromising any
existing features. Its main contents are the transmitter P9242-R3-
EVK Evaluation Board and the receiver P9221-R3-EVK Evaluation
Board.
In customer end systems, the transmitter and receiver boards need
to have external microcontrollers (MCU) to orchestrate the
bi-directional communication. The MCU on the receiver board
loads data into the user outgoing data registers and triggers the
communication by writing to the Command register. The transmitter
receives the data and interrupts the external MCU on the trans-
mitter pad. The transmitter follows the same procedure to send the
data to the receiver. There are no external MCU’s on the
P9242-R3-EVK and P9221-R3-EVK Evaluation Boards. Instead,
IDT I2C Lite, an intuitive I2C-based graphical user interface (GUI),
and two USB-to-I2C dongles are used to emulate external MCUs.
The USB-to-I2C dongles are included in the kit. The latest version
of the IDT I2C Lite software is available on the IDT webpage.
This manual focuses on demonstrating the bi-directional data com-
munication features of the P9242-R3 and P9221-R3. The P9242-
R3-EVK and P9221-R3-EVK offer the flexibility to program param-
eters such as the over-current limit and foreign-object detection
(FOD) limits by changing resistors. Refer to the user manuals for
the P9242-R-EVK Transmitter Evaluation Board and P9221-R-EVK
Receiver Evaluation Board for more details related to programming
parameters.

3. Evaluating Bi Directional Data Communication
3.1 Transferring Data from the Receiver to the Transmitter
To send the data from the P9221-R3 to the P9242-R3, the external microcontroller (MCU) on the receiver loads data into the user outgoing
data registers of the P9221-R3 and triggers the communication by writing to the Command register of the P9221-R3 via the I2C bus. The
P9242-R3 receives the data and interrupts the external MCU on the transmitter pad. The external MCU on the transmitter pad reads the user
incoming data registers via the I2C bus after it receives the interrupt. More details on the data transfer algorithm are in the P9221-R3 and
P9242-R3 datasheets.
There are no external MCUs on the receiver and transmitter evaluation boards in the WP15WBD-RD Evaluation Kit. Instead the IDT I2C Lite
software and USB-to-I2C dongles are used to simulate an external MCU. The USB-to-I2C dongle does not have the capability to generate
interrupts for the IDT I2C Lite software, so it is necessary to poll the Status register to check for incoming data or probe the INT

test point on
the P9242-R3-EVK (IO_B4 test point) using an oscilloscope.
Follow these procedures to transfer the data from the receiver board to the transmitter board:
1. Power up the transmitter and receiver evaluation boards by following the steps in section 1.3.
2. Verify that the green LEDs (identified in Figure 2) on both the transmitter and receiver boards are illuminated indicating that devices are
in the power transfer phase. Bi-directional communication is enabled only when the devices are in the power transfer phase.
3. Connect the USB-to-I2C dongle to the computer’s USB port and connect the I2C header of the dongle to J1 on the P9221-R3-EVK board
as shown in Figure 3. The black wire on the dongle should be on the GND pin of the J1 header.
4. Open the IDT I2C Lite GUI by going to the Windows start menu: IDT GUI Application IDT I2C Lite. Figure 9 shows an overview.
