OM13257 temperature sensor daughter card
1. Introduction
The OM13257 Temperature Sensor Daughter Card connects directly to the OM13320
Fm+ Development kit and permits easy evaluation of most of NXP’s Temperature Sensor
portfolio of products.
Table_1
lists the supported devices.
The OM13257 Temperature Sensor Daughter Card is shipped with no temperature
sensor device soldered to the board. The user must purchase the device he is interested
in evaluating in a TSSOP8 package (the ordering part number suffix should be ‘DP’ and
the package designation should be SOT505-1). These leaded packages should be
relatively easy to solder to the board with a low wattage, fine tipped soldering iron.
Remark:
The pin 1 orientation is down and to the right when the text on the board
readable. Usually, you would expect pin 1 to be up and to the left.
There are two additional package footprints for an XSON8U package (SOT996-2). This
same footprint accepts an HWSON8 package (SOT1169-2) with the exposed center pad
unconnected. This configuration is acceptable for the temperature sensor devices. There
is also a WLCSP6 package footprint for the PCT2202 device. In all cases, the pin 1
orientation is down and to the left when the board text is readable.

3. Board jumper setup
3.1 Power Supply
The power supply selection for the OM13257 is very flexible and allows for detailed
analysis and evaluation of all the NXP temperature sensor devices. JP1 labeled PWR
selects between 5 V supplied from the tester connector CN4 (jumper between pin 2 and
3) and the Fm+ board connector CN5 (jumper between pin 1 and 2). If 3.3 V is desired,
no jumper is required.
JP2 (labeled VDD) selects between 5 V and 3.3 V for the main power supply on pin 8 of
the device under test. Add a jumper between pins 2 & 3 for 3.3 V supplied by the Fm+
board or 1 & 2 for 5 V selected by JP1.
See the schematic section at the end of this document for more details.
3.2 I
2
C Address
The I C address of the slave temperature sensor device is selected via JP10, JP11 and
JP12 connected to pin 5, 6, and 7 of the device under test respectively. Pin 1 of the
jumpers is connected to 0 V, while pin 3 is connected to VDD selected above. Consult
2
the datasheet for the I C addresses corresponding to the logic levels on each pin.
See the schematic section at the end of this document for more details.
2
3.3 SCL and SDA source
There are two I C busses implemented on the Fm+ board and JP3 and JP4 select either
Bus 1 or Bus 2 as a source to the device under test. Jumper between pins 1 and 2 to
select Bus 2 as a source and jumper between pins 2 and 3 to select Bus 1.
Remark:
SCL and SDA from CN4 Tester Connector are always connected to the device
under test. If two masters are used, there may be contention.

4. Connector pinouts
4.1 CN5 Fm+ Development Board connector
The OM13257 can connect directly to the OM13320 Fm+ Development kit via CN2. This
2
connector provides power, I C signals and other ancillary signals.
Remark:
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.

4.2 CN4 Tester connector
Generation, inspection and logging of I C-bus data is easily achieved with third-party
development tools from Total Phase
(http://nxp.com/redirect/totalphase.com)
. There are
two tools called Aardvark and Beagle that direct connect to this board through CN4.
Remark:
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.
