1 Introduction
This document describes the PCA9617ADP-ARD evaluation board. The evaluation board
is built around the PCA9617A, a level translating FM+ I2C-bus repeater, produced by
NXP Semiconductors. The evaluation board serves as a daughterboard that can be
connected through an Arduino port to various Arduino compatible (including original
Arduino Uno R3) EVK/motherboards with the purpose of testing and measuring the
characteristics of the PCA9617A Device Under Test (DUT).
The PCA9617ADP-ARD daughterboard tests and measures the static and dynamic
characteristics of the DUT by accessing an I2C EEPROM from the Arduino port through
the PCA9617A level translator.
The DUT is tested for different logic levels applied to both sides of the level translator, by
supplying the PCA9617A IC with two independent voltage programmable power supplies.
The power supplies are controlled by the motherboard (EVK) through the same Arduino
port. Power is delivered from the motherboard (EVK) through the Arduino port also.
Additionally, a GUI (Windows platform) is provided to facilitate the evaluation of the
daughterboard. The GUI is used with the following NXP evaluation boards: IMXRT1050
EVK Board, LPCXpresso55S69 Development Board, and i.MX 8M Mini LPDDR4 EVK
Board.

The circuit is supplied from the Arduino port through J6 and J4. Pin 4 of J6 is a 3.3
V power supply, while pin 5 of J6 is 5 V power supply. Pin 6 and 7 of J6 and pin
7 of J4 represents the power supply return (ground). LED D1 is the 3.3 V power
supply indicator (VCC_3V3_MAIN power net), and D2 is 5 V power supply indicator
(VCC_5V_MAIN power net). See the SPF-46669_A.pdf schematic file of PCA9617ADP-
ARD daughterboard.
4.5 I2C bus repeater/level translator
Figure 2 shows the I2C-bus repeater and EEPROM section of PCA9617ADP-ARD
schematic diagram. The I2C-bus of the Arduino port (A5 – SCL and A4 – SDA), controlled
by the EVK goes to side “B” of PCA9617A level translator/repeater (U7). U7 (the same
as the DUT) works as an interface between 3.3 V fixed voltage I2C-bus from the Arduino
port and variable voltage I2C-bus of the DUT. Side “A” of U7 is connected to side “A”
of the DUT (U6). The VCCA pins of both ICs are supplied by the LDO1 programmable
power supply (0.8 V to 4.96 V). From side “B” of the DUT (U6), the I2C-bus goes to the
EEPROM (U10). This section of the I2C-bus is also voltage variable; the VCCB pin of U6
and VCC pin of U10 are supplied from LDO2 programmable power supply (2.5 V to 4.96
V). In this way, the user can read/write data from/to EEPROM memory using a host (PC
and EVK) at different voltages across the DUT (PCA9617A level translator). Note that the
EEPROM can operate from 1.7 V to 5.5 V, which is fully compatible with the LDO2 output
voltage range. The jumper headers J15 and J18 allow isolation of the signal pins of the
DUT, so the user can access the level translator directly from outside of the board.
The output enable input of the DUT (pin 5, U6) can be controlled locally from jumper
header J14, or from EVK/GUI. When OE is remote, jumper J14 is placed in position 1-2,
and the OE is controlled through pin 1 of the Arduino connector J1. The OE input has an
internal pullup resistor connected to VCCB pin. Q1 assures the level translation from 3.3
V to VCCB rail voltage.
Jumpers J11, J16, and J17 set the hardware address of the EEPROM memory. The user
should set the I2C control byte accordingly with the hardware address of the EEPROM.
The I2C-bus from the Arduino port can also be accessed from the I2C-bus external
connector (J3). For details, see the SPF-46669_A.pdf schematic file.

4.6 Programmable power supplies
The PCA9617ADP-ARD contains two programmable power supplies: LDO1 and LDO2.
Figure 3 depicts the LDO sections of the schematic diagram. LDO1 provides the power
for VCCA, and LDO2 supplies VCCB power rail. Both regulators are controlled from the
EVK through the Arduino port.
4.6.1 LDO1
The programmable power supply LDO1 consists of an adjustable voltage regulator
LDK120M (U3), and the analog switch 74HCT4052D (U1). The analog switch selects the
resistor divider ratio in the feedback loop of the voltage regulator (U3). Table 2 shows
the output voltages of LDO1 as a function of switch position. U1 is controlled from the
Arduino port through “MUX1_LDO1_S0”, “MUX1_LDO1_S1”, “MUX1_EN_B” (pins 4, 5,
and 6 of the Arduino connector J5). The jumper header J19 allows the user to interrupt
the VCCA rail, to perform current measurements, or to supply VCCA from external.

Table 2. The VCCA programmable voltages
4.6.2 LDO2
The programmable power supply LDO2 is realized with the adjustable voltage regulator
MIC5301 (U4), and the analog switch 74HCT4052D (U2). Similarly, the analog switch
selects the resistor divider ratio in the feedback loop of the voltage regulator (U4). Table 3
shows the output voltages of LDO2 as a function of switch position. U1 is controlled from
the Arduino port through “MUX2_LDO2_S0” and “MUX2_LDO2_S1”, (pins 2 and 3 of the
Arduino connector J5). The control line “MUX2_EN_B” is connected to ground through
pulldown resistor R18. The jumper header J20 allows the user to interrupt the VCCB rail,
to perform current measurements, or to supply VCCB from external.

Figure 3. PCA9617ADP-ARD – LDO1 (up) and LDO2 (down) section
The enable input for both LDOs (U3 and U4) are controlled through an interlock
loop circuit. Both regulators are disabled when “LDO_EN” are pulled down. This is
accomplished when LDO1 switch (U1) is “2Z/2Y3 – ON” and LDO2 switch (U2) is
“2Z/2Y0 – ON”. This combination is true for VCCA = 4.96 V, and VCCB = 2.5 V. The
onboard LED D3 indicates the LDO enable status.
4.7 Jumpers and test points
The board contains eight jumpers and several test points. Table 4 and Figure 4 detail

5 Installing and configuring software tools
PCA9617A_ARD evaluation board is designed and built as a daughterboard able to work
in conjunction with a motherboard equipped with an Arduino port. The board was built to
be fully compatible with the following NXP Evaluation (EVK) boards:
•IMXRT1050 EVK board;
•LPCXpresso55S69 development board;
•i.MX 8M Mini LPDDR4 EVK board
Each of the above-mentioned evaluation/development boards benefit by firmware
support, which can be downloaded from www.nxp.com/. Before starting, the EVK
motherboard must be programmed with the corresponding firmware package.
Additionally, a GUI application (Windows 10) is available for download from the NXP site,
allowing rapid testing and operation of PCA9617ADP-ARD daughterboard through the
one of above mentioned EVKs. The GUI application is common for all three EVKs. The
GUI software is also built to control two daughterboards: the PCA9617ADP-ARD and the
PCA9846PW-ARD (both manufactured by NXP Semiconductors). For details regarding
installation of the EVK firmware and GUI host software on PC please download UM11581
- Arduino Shields GUI and firmware installation available at https://www.nxp.com/docs/
en/user-guide/UM11581.pdf. Once the software is installed, the first step is to select
the correct combination EVK – PCA9617ADP-ARD daughterboard. The board can be
controlled from the GUI interface. See Section 6 and Section 7 for more details regarding
the operation of PCA9617ADP-ARD from GUI software.

6.3 Using the PCA9617ADP-ARD with an i.MX 8M Mini LPDDR4 EVK
board
When an i.MX 8M Mini LPDDR4 EVK board is used with the PCA9617ADP-ARD
board, a third board (IMX8MMINI-IARD interposer board) must be used, especially
designed and built as an EVK – daughterboard 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 PCA9617ADP-ARD daughterboard.

included in the setup assembly. Figure 9 shows the necessary boards and how these
boards are connected. The configuration consists of:
•One i.MX 8M Mini LPDDR4 EVK board
•One PCA9617ADP-ARD daughterboard
•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 PCA9617ADP-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 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) cable from a USB port
on the PC to the debug port (J901) on the EVK (see Figure 9 and Figure 10).
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 www.nxp.com/.

6.4 Using PCA9617ADP-ARD with another device
The PCA9617ADP-ARD daughterboard can be operated with another EVK board, which
has an Arduino port. There are two options to connect the board: using another EVK
equipped with an Arduino port, and an EVK without an Arduino port. In the first case,
firmware shall be developed according to PCA9617A specifications; to operate the board,
attach PCA9617ADP-ARD daughterboard to the EVK. In the second case, using the
Arduino connectors pin chart (Table 1), 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. Refer to PCA9617A datasheet to read details about
internal registers of the DUT IC and data exchange between internal controller and the
EVK. Check for correct electrical connections and avoid data conflicts on the signal lines,
to prevent IC damage.

7 GUI description
A GUI application is available for the three EVK boards from NXP Semiconductors.
The application is common for all three EVKs described in Section 6, and the following
development boards: PCA9617ADP-ARD and PCA9846PW-ARD.
This section describes the GUI application and how the user can control the
PCA9617ADP-ARD daughterboard from the graphical interface. First, install the GUI
package and software on the PC (Windows 10). For more details, see UM11581.
Once installation is complete, assure that one of the mentioned three EVKs with
attached PCA9617A-ARD daughterboard is connected to a PC and powered-on. Open
“NXP_GUI(PCA9617A,PCA9846)” GUI application. An interface appears as shown in
Figure 11:
The GUI application starts with Settings tab (marked with red arrow). The left side of the
window displays Board settings. The section provides the following settings:
• Select EVK: displays the list of EVKs. Selecting a wrong EVK board causes the
connection to fail and a pop-up window with the message: “Unable to Connect with
EVK” appears on the screen.
• Select COM port: displays port selected for the communication. The port is
automatically selected by the system (COM 3 is selected in Figure 11).
• Select Board: allows the user to select the correct daughterboard (the application can
support two different boards). In Figure 11, the selected board is PCA9617A. Selecting
the wrong daughterboard causes the connection to fail and a pop-up window with the
message: “Unable to Connect with Daughter Card” appears on the screen.
Assuming the correct parameters are chosen, clicking the Connect button establishes
the connection with the EVK. In the bottom side of the GUI window, a status bar shows in
real time the status regarding connection between PC and the EVK.
In the right side of the window is the Device setting section. The following settings are
provided:
• DUT EN: sets the OE status of the DUT, when this parameter is controlled from remote
(J14, jumper in position 1-2). With the Set button the value is written in the internal
register of PCA9617A IC.
• I2C Frequency: displays the I2C-bus clock frequency (100 kHz, 400 kHz, and 1 MHz).
With the Set button the value is written in the internal register of PCA9617A IC.
• EEPROM Address Selection: allows the user to select the hardware address of
PCA9617A.
The Set button writes the new values in the internal registers of PCA9617A IC. When
the Set button is pressed, a pop-up window with the message: “Setting device Set
successfully” appears on the screen. Click “OK” to close the pop-up window.
