1. Introduction
The OM13489 16-bit I2C GPIO Daughter Card connects to the OM13320 Fm+ Development
kit and permits easy evaluation of most of NXP’s 16-bit I2C GPIO portfolio of products.
Table_1 lists the supported devices.
The OM13489 16-bit I2C GPIO Daughter Card is shipped with no GPIO device soldered to
the board. The user must purchase the device he is interested in evaluating in a TSSOP24
package (the ordering part number suffix should be “PW” and the package designation
should be SOT355-1). These leaded packages should be relatively easy to solder to the
board with a low wattage, fine tipped soldering iron.
NOTE pin 1 orientation pointing toward C1.
Please note that a fix is needed for correct operation of the A0 jumper JP1. A wire must
be soldered between pin 2 of JP1 and the via directly below to make connection to pin 21 on
the device under test IC1. See Section 3.2 for additional details.

3.1 Power Supply Setup
Power supply voltages may be selected from the tester connector CN4 or the Fm+ board
CN5. If one selects Fm+ CN5, either 3.3V or 5V can be chosen. Additionally, the
PCA(L)6416 device implements two power supplies which are separately chosen, i.e. one
can be 3.3V and the other 5V for voltage level translation evaluation. Both of these power
supplies can be supplied externally by using TP1 and TP2 near the tester connector CN4.
See the schematic section at the end of this document for more details.
The jumpers for power supply selection are CN3, JP3, and JP4
3.2 Reset, Interrupt, and Address pins selection
The Reset, Interrupt and Address pins are used in combinations on various devices. The
selection matrix on the 16-bit GPIO board sends pins 1, 2, and 3 to determine if the pins are
address or function on JP9, JP10, and JP11. Then, if they are determined address pins, JP1,
JP7 and JP8 tie them to logic high or low. If they are determined to be function pins, the
other position of JP9, JP10 and JP11 tie them to the correct connector function pins. See the
schematic section at the end of this document for more details.
The logic high level for the address pins is VDDP .
Please note that a fix is needed for correct operation of the A0 jumper JP1. A wire must
be soldered between pin 2 of JP1 and the via directly below to make connection to pin 21 on
the device under test IC1. Use 30 AWG wire wrap wire for the easiest connection. The solder
mask on the board will prevent any short circuits.
Please note that A1 and A2 jumpers are incorrectly labeled. JP7 and JP8 program I2C
addresses when selected. The labels show that A1 and A2 pins will be connected to ground
when the jumper shorts pin 1 and 2 (toward the bottom edge of the board). In fact, this is a
connection to VDDP or high. The schematic is correct, only the labels are incorrect.
Fig 2. Fix needed for correct operation of A0 jumper JP1
4. Board Jumper Set Up
4.1 Power Supply Jumpers
The power supply selections for the OM13489 is very flexible and allows for detailed analysis
and evaluation of all the NXP 16-bit GPIO devices. JP3 labeled PWR selects between 5V
supplied from the tester connector CN4 (jumper between pin 2 and 3 labeled TSTR) and the
Fm+ board connector CN5 (jumper between pin 1 and 2). If 3.3V or external power operation
is desired, no jumper is required.

CN3 selects between 5V and 3.3V for a second power supply needed for PCA(L)6408A. If
the device under test is not PCA(L)6408A, leave this jumper open.
JP4 selects between 5V and 3.3V for the main power supply on pin 16 of the device under
test. Add a jumper between pins 2 & 3 for 3.3V or 1 & 2 for 5V.
For external power supply operation, do not jumper CN3, JP3 and JP4 and connect a voltage
source to TP2 for the main power supply connected to pin 16 of the device under test.
Connect another external voltage source to TP1 if the device under test is PCA(L)6408A.
See the schematic section at the end of this document for more details.
Fig 3. Power Jumpers and External Power Test Points
4.2 SCL and SDA Jumpers
The I2C-bus signals SDA and SCL supplied to the device under test can be sourced from
either the Fm+ board via CN5 or the tester via CN4. Jumpers JP5 and JP6 select the source.
Shorting pins 1 to 2 source from the Fm+ board while shorting pins 2 to 3 source from the
tester connector CN4.
See the schematic section at the end of this document for more details.

PCA9675, PCAL9535A, PCAL9555A, PCF8575
The PCA8575, PCA9535/A/C, PCA9555/A, PCA9675 and PCF8575 series implement three
address pins and INT . This configuration ignores the power supply setup, but normally,
only JP4 with a jumper between pins 2 & 3 need be applied to power the device at 3.3V.

To configure the function pins, apply jumpers between pins 1 & 2 on JP10 and JP11 to
configure device pin 2 and pin 3 as addresses. Apply a jumper between pins 2 & 3 on JP9 to
configure device pin 1 as INT .
Then, apply jumpers to JP1, JP7 and JP8 to configure the desired I2C address. Logic high or
logic low is labeled on the board, but is incorrect for JP7 and JP8. Using the labels, a 0 is
actually a 1 and a labeled 1 is actually a 0. The schematic is correct and note the square
solder pad is pin 1.

4.5 PCA9673, PCAL9539A, PCA9539A, PCA9539R, PCA9539
The PCA9673 and PCA9539 series implement two address pins, RST and INT . This
configuration ignores the power supply setup, but normally, only JP4 with a jumper between
pins 2 & 3 need be applied to power the device at 3.3V.
To configure the function pins, apply jumpers between pins 2 & 3 on JP9 and JP11 to
configure device pin 3 as RST and device pin 1 as INT . Apply a jumper between pins 1 &
2 on JP10 to configure device pin 2 as an address.
Then, apply jumpers to JP1 and JP7 to configure the desired I2C address. Logic high or logic
low are labeled on the board. Leave JP8 open. The labels are incorrect for JP7 and JP8.
Using the labels, a 0 is actually a 1 and a labeled 1 is actually a 0. The schematic is correct
and note the square solder pad is pin 1.

4.6 PCAL6416A, PCA6416A
The PCA(L)6416A devices are level translating, Agile I/0 Expanders with two power supplies,
one address pin, RST and INT . The two power supplies may operate at different voltages
to translate from the I2C-bus voltage domain to a higher or lower I/O voltage. CN3 and JP4
may be set to the same or different voltages, or left open and external voltage sources
connected to TP1 and TP2. See the datasheet for more details on voltage level translation.
Note that the 10K pull up resistors SDA and SCL, R5 and R6, are connected to VDDP which
may cause incorrect current readings if two different supplies are used.
To configure the function pins, apply jumpers between pins 2 & 3 on JP9, J10 and JP11 to
configure device pin 2 as a power supply, device pin 3 as RST and device pin 1 as INT .
Then, apply a jumper to JP1 to configure the desired I2C address. Logic high or logic low are
labeled on the board. Leave JP7 and JP8 open.

5. Connector Pinouts
5.1 CN1 GPIO Target Board Connector
The OM13303 GPIO Target Board consists of eight LEDs and eight switches and connects
directly to the 16-bit GPIO board through CN1. The switches and LEDs permit easy exercise
of the I/O functionality of the device under test. The LEDs light red when the voltage on that
channel is below VCC x 0.3V and lights green when the voltage is above VCC x 0.7V. The
LEDs remain off when the voltage is between those two levels.

5.2 CN5 Fm+ Development Board Connector
The OM13489 can connect directly to the OM13320 Fm+ Development kit via CN5. This
connector provides power, I2C signals and other ancillary signals.
Note: The connector on the Fm+ board is a male, shrouded 14 pin type, while the connector
on the GPIO board is female, 18 pin.. The reason lies with the shroud around the 14 pin
connector. To ensure correct mating of the female with the male, two pin positions on both of
the female sides are unused.

Generation, inspection and logging of I2C-Bus data is easily achieved with third party
development tools from Total Phase (www.totalphase.com) There are two tools called
Aardvark and Beagle that direct connect to this board through CN4.
Note: Since SDA and SCL are both connected to the device under test, the Aardvark and the
Fm+ Development board cannot be used simultaneously. The Beagle, a bus sniffer, does not
have any issues.
