WP15WBD-RK Bi-directional Data Transfer Evaluation Kit User Manual for the P9221-R3 and P9242-R3

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-R3EVK 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 transmitter 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 communication features of the P9242-R3 and P9221-R3. The P9242R3-EVK and P9221-R3-EVK offer the flexibility to program parameters 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.

1.3 Kit Hardware Connections
Follow these procedures to set up the kit as shown in Figure 2. 1. Plug the 12V adapter or user's power supply into the J3 barrel connector on the bottom of the P9242-R3-EVK board (see Figure 7). 2. Place the P9221-R3-EVK on the transmitter (TX) pad with the components facing up as shown in Figure 2. 3. Verify that the two green LEDs identified in Figure 2 are illuminated indicating that coupling has been established. 4. Connect wires to the VOUT and GND test points on the P9221-R3-EVK receiver to measure the output voltage (see Figure 6) and apply
a load requiring less than the programmed current limit. 5. Connect the USB-to-I2C dongle to the computer's USB port. If using a second computer, connect the second dongle to its USB port. 6. To send I2C commands to the P9221-R3-EVK, connect the I2C header on one of the connected dongles to J1 on the P9221-R3-EVK as
shown in Figure 3. The black wire on the dongle should be on the GND pin of the J1 Header. See sections 3.1 and 3.2 for detailed instructions. 7. To send I2C commands to the P9242-R3-EVK, connect the I2C header on one of the connected dongles to J2 on the P9242-R3-EVK as shown in Figure 4. The black wire on the dongle should be on the GND pin of the J2 header. See sections 3.1 and 3.2 for detailed instructions.

Note: The P9242-RB IC is used on the P9242-R3 V2.1 Evaluation board instead of the P9242-R3 IC. The P9242-R3 has bi-directional communication firmware pre-programmed into its one-time programmable memory and does not allow the firmware to be customized. The P9242-RB offers a pre-programmed bootloader that must be used in conjunction with an external flash. Bidirectional communications firmware is loaded into the external flash. The firmware can be customized in external flash. There is no functionality difference between the P9242-R3 V2.1 Evaluation board with P9242-R3 IC and the P9242-RB with external flash.

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.

5. Verify the proper USB dongle connection by checking the USB icon status in the top right corner of the GUI. When the USB dongle is properly connected, the USB icon should be bright blue and the bottom left corner should indicate "IDT dongle connected."
6. Select "P9221 RX" from the "Device" drop-down menu in the GUI.
7. Verify that the proper P9221-R3-EVK connection is recognized by the GUI by checking the device icon in the top right corner of the GUI. When the P9221-R3-EVK is properly connected, the selected device icon should be bright blue and the message in the middle of the bottom status bar in the GUI should indicate "P9221 connected."
8. Click "Open Script" from the "File" menu in the top left corner of the GUI, and navigate to the "Send 8 bytes from Rx to Tx" script. This script has all the I2C commands required to send the data from the P9221-R3 to the P9242-R3. The script can be customized by using the "+" and "�" buttons in the GUI.
9. Click the "Run all" button to run all the I2C commands in the script to send the data from the P9221-R3 to the P9242-R3.
10. If using only one computer, gently disconnect the dongle I2C header from the receiver board, and connect the I2C header to J2 of the P9242-R3-EVK transmitter board as shown in Figure 4. The black wire on the dongle should be on the GND pin on the J2 header.
If using two computers, follow the subsequent steps on the second computer to read the data.
11. Select "P9242 TX" from the "Device" drop down menu in the GUI.
12. Verify the proper P9242-R3-EVK connection to GUI by checking the selected device icon in the top right corner of the GUI. When the P9242-R3-EVK is properly connected, the icon should be in bright blue color and the bottom status bar in the GUI should indicate "P9242 connected."
13. Click "Open Script" from the "File" menu in the top left corner of the GUI, and navigate to the "Read 8 bytes of data on Tx" script. This script has all the I2C commands required to read data coming into the P9242-R3. The script can be customized by using the "+" and "�" buttons in the GUI.
14. Click the "Run all" button to run all the I2C commands in the script to read the incoming data in the P9242-R3.
15. Verify that the incoming data on the P9242-R3 matches the P9221-R3 outgoing data.

8. Click "Open Script" from the "File" menu in the top left corner of the GUI, and navigate to the "Send 2 bytes from Tx to Rx" script. This script has all the I2C commands required to send the data from the P9242-R3 to the P9221-R3. The script can be customized by using the "+" and "�" buttons in the GUI.
9. Click the "Run all" button to run all the I2C commands in the script to send the data from the P9242-R3 to the P9221-R3.
