3.5 Connector pinouts
• J1
(10-pin male tester connector) is connected to master which is driving either I
2
C-
bus for PCAL6534. This is easily achieved with third party development tools from Total
Phase ( http://www.totalphase.com ). There are two tools called Aardvark and Beagle
that direct connect to this board through J1.
Table 1. J1 10-pin tester connector
J1 Pin # Function Board connection
1 SCL U1 pin A3 (PCAL6534)
2,10 GND Ground
3 SDA U1 pin A2 (PCAL6544)
4, 6 +5V_TSTR J13 pin 3
5 SDOUT (MISO) NC
7 SCLK NC
8 SDIN (MOSI) NC
9 /CS (SS) NC
Note
: Since SDA and SCL are both connected to the device (U1) under test, the
Aardvark and the Fm+ Development board cannot be used simultaneously. The Beagle,
a bus sniffer, does not have any issues.
• J11
(18-pin female connector) can connect directly to the OM13260 Fm+ Development
board. This connector provides power, I
2
C signals and other ancillary signals.
Table 2. J11 18-pin Fm+ board connector
J11 Pin # Function Board connection
1, 2, 9, 10, 17, 18 GND Ground
3 SCL2 SCL Bus 2 to J9 pin 3
4 SDA1 SDA Bus 1 to J10 pin 1
5, 14 INT Interrupt to U1 pin B1, LED (D1) and TP4 (test point 4)
6, 13 RESET U1 pin A5 and J5 pin 1
7, 12 +5V J3 pin 1
8, 11 +3V3 J2 pin 1 and J7 pin 1
15 SDA2 SDA Bus 2 to J10 pin 3
16 SCL1 SCL Bus 1 to J9 pin 1
Note : The connector on the Fm+ board is a male, shrouded 14 pin types, while the
connector on this 34-bit GPIO board is an 18-pin female. 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 female sides are grounded.
• J12, J13, J14, J15, J16 (10-pin male connector) is connected to GPIO target board
(OM13303) which consists of eight LEDs and eight switches and connects directly to
this 34-bit GPIO board through J12 (I/O of port 0), J13 (I/O of port 1), J14 (I/O of port
2), J15 (I/O of port 3), J16 (I/O of port 4). These switches and LEDs on GPIO target
board 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 VDDP x 0.3V and LEDs light green
