1 Hardware Description and Setup

The general procedure for setting up the FPC401 and FPC402 Evaluation Modules (EVM) is described in

the following sections.

Figure 1. FPC40xEVM – Top and Bottom

1.1 Power Configuration

Configure the power illustrated by Figure 2.

1. If the LDO is used to power the FPC, enable the LDO through header J8 and connect the LDO output

to VDD1 using header J4 (note that each header connection is rated for 1 A of current). Make sure

headers J7 and J13 are disconnected. The LDO has a maximum rated current of 1.5 A, so if the

cumulative QSFP/SFP module current draw is greater than that, the LDO may not be used.

2. If the LDO is not used and the FPC is powered through an external supply, configure the J8 header to

disable the LDO and connect VIN to VDD1 using header J7 (note that each header connection is rated

for 1 A of current). Make sure headers J4 and J13 are disconnected.

3. If USB power is used to power the FPC, ensure the LDO and VIN and disconnected from VDD1

(disconnect headers J4 and J7). Connect the 3.3 V of the MSP430 microcontroller to VDD1 through

header J13. Note that a typical computer USB port is only able to supply up to 100 mA which will be

enough to power the FPC and passive modules (that is, DAC); but it will not be enough to power active

SFP+ and QSFP+ modules which are plugged in.

4. To set VDD2 to 3.3 V, connect it to VDD1 through header J2. To operate at lower host-side supply

voltages (down to 1.8 V), connect an external supply to the header or test point loop (TP3).

5. The FPC401EVM and FPC402EVM includes a TPS2561 power switch which is used to selectively

enable and disable 3.3-V power to the SFP and QSFP ports. The FPC controls this power switch with

its GPIO pins. To supply power to ports 0 and 1 (QSFP+ ports and LEDs), configure the FPC GPIO0

high logic output to enable the power switch. Similarly, configure GPIO1 to high logic to enable power

for ports 2 and 3 (SFP+ ports and LEDs). Alternatively, supply 3.3 V externally through the test points

(TP4 and TP5). Note that the ground is shared with the board.

6. GPIO2 and GPIO3 are connected to the fault outputs of the power switch, and hence should be set as

inputs or left unconfigured.

1.2 Communication Protocol Configuration

The following sections describe how to configure the FPC401EVM and FPC402EVM for I2C and SPI

protocols.

1.2.1 I2C Configuration

For I2C communication with the onboard MSP430, refer to Figure 3 and configure the board based on the

following procedure.

1. Leave the PRTCL_SEL pin disconnected (header J3).

2. Connect the MSP430 SCL and SDA to the FPC SCL and SDA through header J12. The SPI header

(J9) should be disconnected.

3. Connect the 2.7-kΩpullup resistors through header J1.

4. Connect the VDD2 pin to the VDD1 pin through header J2.

5. Connect the ADDR_N pin to GND through header J2 with the provided jumper wire.

For I2C communication with an external host controller, disconnect the MSP430 SDA and SCL. Connect

the FPC SDA and SCL pins to the SDA and SCL pins of the host controller. Only connect the onboard

pullup resistors if the host board does not have pullups.

To control multiple EVMs, connect all the SDA and SCL pins together. Only one board should have the

MSP430 and pullup resistors connected to these pins. The ADDR_N of the first device should be tied to

GND as shown in Figure 3 . Connect DONE_N pin of the first device to the ADDR_N of the second

device, and the DONE_N pin of that device to the following device in a daisy-chained fashion until all

ADDR_N pins are connected. Connect the final DONE_N pin to GND. See the data sheet for more details

on how I2C is configured.

1.2.2 SPI Configuration

For SPI communication with the onboard MSP430, refer to Figure 4 and configure the board based on the

following procedure.

1. Connect the PRTCL_SEL pin to GND through header J3.

2. Connect the MSP430 MISO, MOSI, SCK, and SS_N pins to the FPC MISO, MOSI, SCK, and SS_N

pins through header J9. The I2C header (J12) should be disconnected.

3. Connect the VDD2 pin to the VDD1 pin through header J2.

For SPI communication with an external host controller, disconnect the MSP430 MOSI, MISO, SCK, and

SS_N pins. Connect the FPC MOSI, MISO, SCK, and SS_N pins to the MOSI, MISO, SCK, and SS_N

pins of the host controller.

To control multiple EVMs with SPI, connect all the SCK and SS_N pins to a single MSP430 SCK and

SS_N pins. Daisy chain the MOSI and MISO pins so that the MOSI of the MSP430 connects to the MOSI

of the first device, the MISO of the first device connects to the MOSI of the second device, and so on, until

the final device's MISO connects to the MISO of the MSP430. See the data sheet for more details on how

SPI is configured.

2.1 Installation

The FPC401 EVM GUI has two installers. The Setup_FPC401_EVM.exe installer does not contain the

National Instruments Run-Time Engine and requires web access to download the NI run-time engine if the

computer does not already have this installed. The Setup_FPC401_EVM_with_RTE.exe installer is a

larger file that contains the run-time engine and does not require web access. Select the appropriate

installer and follow the installer wizard to install the FPC401 EVM GUI.

2.2 Initializing Communication

To initialize communication with the FPC401EVM, first select the number of FPC401s under FPC Count

and the protocol (I2C or SPI), highlighted by Figure 6. Click OPEN LINK to establish communication with

the MSP430 through USB and initialize the device. In I2C mode, this will configure the MSP430 and

automatically configure the I2C addresses of all connected FPC401s so that each one has a unique

address. In SPI mode, this will configure the MSP430 and establish the length of the SPI message. Each

time the hardware configuration changes, the link must be reestablished. For example, connecting

additional FPC401s or changing the communication from I2C to SPI requires the link to be reestablished.

The TOGGLE LED button will toggle the LED (D7) for a visual indication that the USB communication is

working. The text in the bottom of the GUI should say CONNECTED and turn green after USB

communication is established. Note that this means that the computer is communication with the MSP430

but does not necessarily mean that communication is established with the FPC401.

The CLOSE LINK button will terminate USB communication.

SNLU222B–December 2016–Revised September 2019

FPC401 and FPC402 Evaluation Module (EVM) User’s Guide

The top right section of the GUI highlighted by Figure 7 controls the FPC(s) being programmed by all

controls in this GUI. The Instance # selects which FPC is being controlled, starting at instance 0. The Port

#selects which port is being configured, where 0 is the port 0 of FPC instance 0, and 4 is port 0 of FPC

instance 1. The Broadcast switch will broadcast commands to all FPCs if set to 1. Note that if a command

that targets a port is broadcasted, not all ports will be modified. Instead, only ports that match the local

port of the selected instance are modified. For example, broadcasting a command that targets port 5 (local

port 1 of instance 1) will affect ports 1, 5, 9, 13, and so forth.
