4.1 Using the PCF85063TP-ARD with an IMXRT1050 EVK Board

Figure 2 shows the required hardware for operation of the PCF85063TP-ARD daughter board with IMXRT1050 EVK. The following items are necessary:

  • One IMXRT1050-EVK board
  • One PCF85063TP-ARD daughter board
  • One USB-A / USB Micro-B cable
  • A PC with Windows 10 operating system

The IMXRT1050 EVK motherboard can be powered by one of the three methods:

  • Connecting an external 5VDC power supply to the barrel power connector (J2) on the board
  • Connecting a USB cable from the PC to the Micro-B USB connector (J9) on the board
  • Connecting a USB cable from the PC to the USB connector (J28) on the board. When the PC is connected in this fashion, the USB port can simultaneously act as a debug interface. Therefore, by using a single USB cable connected to J28, the EVK can be powered and at the same time linked to the PC for data exchange.

The older USB ports (from PC) are not able to deliver the necessary current (500 mA). Before establishing the communication, use an external power supply (connected to J2).

From J1 on the EVK board (see Figure 2), the user can select the power configuration for the motherboard. For further details, refer to the MIMXRT1050 EVK Board Hardware User Guide.


Figure 2. PCF85063TP-ARD daughter board and IMXRT1050 EVK board, before starting


To configure the hardware and workstation, complete the following procedure:

  1. Configure the suitable power configuration of EVK (J1). If using J28 for power supply, the J1 jumper shall be placed in position 5-6. If using an external power supply (connected to J2), the jumper J1 will be placed in position 1-2.
  2. Insert the PCF85063TP-ARD daughter card on the Arduino connector of the EVK (see Figure 3).
  3. Using the USB connector J28, connect the EVK board to a USB port of the computer.
  4. Install the IMXRT1050 target firmware (download from NXP site and see UM11581, Arduino Shields GUI and Firmware Installation Manual for step-by-step instructions).
  5. Install GUI application (see UM11581, Arduino shields GUI and firmware installation manual).
  6. Open the GUI application to operate the device from the PC.

Figure 3 shows the boards during the operation.

4.3 Using the PCF85063TP-ARD with an i.MX 8M Mini LPDDR4 EVK Board

When an i.MX 8M Mini LPDDR4 EVK board is used with the PCF85063TP-ARD board, a third board (IMX8MMINI-IARD interposer board) must be used, especially designed and built as EVK - daughter board interconnection. The EVK board i.MX 8M Mini LPDDR4 is not equipped with an Arduino port; instead it has a 2 x 20-pin expansion connector (J1003, see i.MX 8M Mini LPDDR4 EVK user manual). J1003 is a multipurpose port, containing various digital I/O lines, including specialized I2C and SPI buses. Starting from the expansion connector pin chart, an Arduino port interposer board was developed, with the role of signal-to-signal bridge between the 2 x 20 connector pins on the i.MX 8M Mini LPDDR4 EVK and the mated connectors of the Arduino port present on the PCF85063TP-ARD daughter board.

To operate the setup, along with the EVK and the daughter board, a third board must be included in the setup assembly. Figure 6 shows the necessary boards and how these boards are connected. The configuration consists of:

  • One i.MX 8M Mini LPDDR4 EVK board
  • One PCF85063TP-ARD daughter board
  • One IMX8MMINI-IARD interposer board
  • One USB-A / USB-C cable
  • One USB-A / USB Micro-B cable
  • A PC with Windows 10 operating system

It is recommended to attach the PCF85063TP-ARD to the Arduino connectors of the IMX8MMINI-IARD interposer board first, and then the resulting assembly to the i.MX 8M Mini LPDDR4 EVK. This can be done by plugging J1 connector located on the interposer board to J1003 connector on the EVK.

To power-up the EVK, a USB-C type cable connected to PORT 2 of the EVK is used. The power switch SW101 on the EVK board must be set to ON position to power-up the setup. Data communication is achieved by routing a separate USB (Micro-B type) cable from a USB port on the PC to debug port (J901) on the EVK (see Figure 6 and Figure 7).

The user may find details regarding power-up and operation of the setup assembly in 8MMINILPDDR4-EVK User Manual and IMX8MMINI-IARD User Manual. The files can be downloaded from NXP.com.


Figure 6. Overview of the assembly PCF85063TP-ARD daughter board, IMX8MMINI-IARD interposer board and i.MX 8M Mini LPDDR4 EVK, before starting

To configure and operate the setup, follow the below steps:

  1. Insert the PCF85063TP-ARD onto the IMX8MMINI-IARD interposer board Arduino connectors (located on the top side).
  2. Attach IMXMMINI-IARD connector plug J1 (located on the bottom of the board) into J1003 expansion board located on the top side of i.MX 8M Mini LPDDR4 EVK (see Figure 6).
  3. Power-up the EVK board using a USB Type C cable attached to PORT 2.
  4. Connect the EVK to the PC, using a USB Micro-B cable, attached to J901 debug port.
  5. Place SW101 in ON position to power up the boards.
  6. Install the MIMXRT1050 target firmware (download UM11581, Arduino shields GUI and firmware installation manual from NXP site).
  7. Install GUI application on the PC (see the instruction file referenced in the the above step).
  8. Open the GUI application to operate the device from the PC.

4.4 Using PCF85063TP-ARD with Another Device

The PCF85063TP-ARD daughter board can be operated with other EVK board, which has an Arduino port. There are two options to connect the board: using other EVK equipped with an Arduino port, and an EVK without Arduino port. In the first case, a firmware shall be developed according with PCF85063TP specifications, and then simply attach PCF85063TP-ARD daughter board to the EVK to operate the board. In the second case, using the pin chart of Arduino connectors, make the necessary electrical connections (for power, I2C-bus and control lines), and develop the desired firmware, assuring that it is compliant with IC specifications. Use PCF85063TP data sheet to read details about internal registers of the DUT IC and data exchange between internal controller and the EVK. Assure for correct electrical connections and avoid data conflicts on the signal lines to prevent IC damage.
