Overview
2 Overview
2.1 Functional overview
This EVB is designed for use with the FPMM and FPSM. All the modules supplied in the kit are connected to form
a complete system. The evaluation board can interface with a PC through the USB port using the built-in USB-to-
UART Bridge chip. The embedded framework FW and host interface command protocol are built into the FPMM
module. A software GUI (FPMM SW) to interact with the FPMM module is also provided. With these components,
the user can develop embedded fingerprint reader-based solutions and evaluate the Infineon embedded
fingerprint solution.
The EVB is designed to allow a host processor that is using the host communication protocol to access the FPMM
board through the following physical interfaces:
1. USB-to-UART Bridge: UART-to-USB Bridge is built into the evaluation board
2. UART: Direct UART connection is available on the expansion connector of the evaluation board
3. SPI: Direct SPI connection is available on the expansion connector of the evaluation board. Not supported in
this revision.
4. I2C: Direct I2C connection is available on the expansion connector of the evaluation board. Not supported in
this revision.
5. CAN: Direct Can connection is available on the expansion connector of the evaluation board. Not supported
in this revision.
6. Standalone GPIO mode: FPMM can be controlled using only GPIOs. The status of various phases of FPMM
operation returns through GPIOs. These GPIOs can either be connected to the push button switches on EVB
and status returned through the three-color LED on the EVB or connected to the expansion connector for any
host to use a simple GPIO-based interface to control the FPMM. Not supported in this revision.
The EVB can also be used to provide a direct connection between a host processor and the FPSM when the FPMM
is not plugged in. The EVB can be used to allow any host to directly connect to the SPI interface of the FPSM by
connecting jumper wires to the FPMM connector pins that run to the FPSM. In this mode, the host processor of
choice is running the Infineon embedded framework software to be able to communicate with the FPSM. Details
of this mode are provided in “Direct FPSM connection to host” on page 23.

3 Connection and settings
This section describes the various switches and headers available on the EVB. Confirm the settings are according
to the intended use or if using the EVB without modifications confirm the header jumpers and switches are at
default state as indicated in the following sub-sections before turning on the power supply or connecting the USB
cable.
3.1 Power supply settings
The EVB can be powered using either a 5 V DC power supply connected to the expansion connector (J16) or
through USB bus power connected to J13. Power select header J1 is used to decide whether power is to be taken
from the external expansion connector pin for USB bus power. Table 3-1 shows how to configure J13. The input
power supply voltage range is 3.3 V to 5 V and the current requirement of 500 mA. Do not exceed or go less than
the maximum and minimum voltage requirements.

3.2 RESET switch and RESET select header
The reset switch is a push button used to RESET the FM4 device on the FPMM. This reset signal is connected to the
XINIT signal of the FPMM. The reset is an active low reset. The XINIT pin of FPMM can be driven from either the
push button reset switch SW 1 or the expansion connector J16. These selections of where the reset is driven from
are selected on the RESET select header.

3.3 USB-to-UART Bridge (CMSIS-DAP -FM3)
The FM3 processor (U1) on the EVB performs the function of a USB-to-UART Bridge chip. The FM3 processor
comes programmed with the correct firmware to perform the UART-to-USB bridging function. The MD0 pin of the
FM3 part requires to be in the normal mode of operation when not programming this controller. Table 3-3 shows
the switch settings for the MD0 pin. The USB_UART bridge chip programming is not a user mode available option.

3.6 WAKEUP switches and WAKEUP select header
The wakeup push button switch (SW4) is used to wake up the FPMM from a low-power mode. This push button is
used to provide a wakeup signal to the VBAT_wakeup pin of the FPMM. The location of this push button switch is
shown in Figure 3-6. The wakeup signal is an active high signal.
Figure 3-6. Wakeup switch
The wakeup signal to the FPMM can be driven from either push button SW4 or the external connector J10. Jumper
J8 is used to select which circuit will drive the wakeup signal. Table 3-7 shows the wakeup select jumper
configurations.

3.7 GPIO switches and GPIO select headers
Note: GPIO functionality is not available in this revision.
Configure the GPIO switches on the EVB to perform various input/output functions according to the firmware
configuration used. Primarily these switches are used in the standalone BOOT mode of operation of the FPMM
(BOOT [2:0] = 100).
In this mode, the FPMM firmware configures these GPIOs to be used as fixed function inputs, e.g., one switch to
enter ENROLL phase, one switch to enter VERIFY phase, and the third switch to delete the ENROLLED template.
See the FPMM user guide for the firmware functionality of these switches. Table 3-8 shows the mapping of these
GPIOs to the GPIO switches.

GPIO select headers allow the FPMM GPIO signals to connect to either the push button on the EVB or the
expansion connector J16.
Note: Currently, none of the GPIO push button switches are used.

Note: SPI functionality is not available in this revision.
The SPI interface from the FPMM connects to the expansion connector through this header. Figure 3-10 shows
the SPI headers. The signals CAN_TX and CAN_RX share with SPI signals. Depending on the BOOT mode settings,
the FPMM can use SPI_CLKI and SPI_MOSI for either the SPI interface or the CAN interface.
Note: Do not change the default connection of the SPI headers.

3.9 UART select headers
The UART interface from the FPMM can be connected either to the expansion header (J16) or the USB-UART
Bridge chip. The Infineon embedded fingerprint solution uses the UART interface through the USB-to-UART
Bridge to demonstrate the functionality of this solution. A PC-based software demo has been developed for this
purpose. For implementations that require UART to be connected to a HOST directly, route the UART signals to
the expansion connector (J16).

3.10 Expansion connector
The expansion connector on the EVB exposes the communication interfaces, reset, GPIOs, and wakeup signals of
the FPMM to external hosts. The later sections describe the configuration of the various select headers to route
signals from the FPMM to the expansion connector.

3.11 Current measurement header
The current measurement header J19 provides a way to measure the current consumed by the FPMM and FPSM
modules. The host power plane in the EVB is separated from the rest of the 3.3 V power plane by a 0-ohm resistor.
Measures the current flowing through this resistor to determine the current consumption of the two boards. J19
header Pin 1 is placed on the EVB power plane side of the 3.3 V supply and J19 header Pin 2 on the HOST_POWER
(FPMM and FPSM) side of the 3.3 V power plane.
