OM-SE050ARD hardware overview
2 Overview
The OM-SE050ARD is the development kit for the SE050 Plug & Trust product family.
This kit allows you to evaluate the SE050 product family features and simplifies
the development of your custom applications. Figure 1 shows a picture of the OM-
SE050ARD.
Figure 1. OM-SE050ARD development kit
2
The SE050 uses I C as communication interface and its commands are wrapped using
the Smartcard T=1 over I²C (T=1oI2C) protocol. In addition, the SE050 supports the
following interfaces:
2
• I C interface in slave mode with date rates up to 3.4 Mbps .
2
• I C interface in master mode with date rates up to 400 Khz.
• ISO/IEC 14443 T=CL protocol.
The OM-SE050ARD flexible design makes it possible to access the SE050 interfaces by
just changing a few jumper settings.
2 2
Note: Only the I C slave interface is mandatory. The I C master and ISO/IEC 14443
interfaces are optional.

3 Headers and connectors
The OM-SE050ARD is designed with several headers and connectors that allow you to
interface with SE050. The OM-SE050ARD is equipped with:
• Arduino-R3 header: It allows you to easily attach it to any NXP MCU/MPU
development board with Arduino compatible headers such as many Kinetis, LPC and
i.MX MCU boards. The Arduino-R3 female connectors come soldered in the OM-
SE050ARD.
2
• External I C connector: It allows you to connect any non-Arduino compatible MCU
2
boards via I C slave interface. The OM-SE050ARD includes the mounting holes for the
2
External I C connector.
2
• 10-pin header: It allows you to access several pins of the SE050, including the I C
master interface to attach sensors or peripherals to the board. The 10-pin header male
connectors come soldered in the OM-SE050ARD.
• DB15 header: It allows you to access several pins of the SE050, including the ISO/IEC
2
14443 or the I C master interface to attach sensors or peripherals to the board. The
OM-SE050ARD includes the mounting holes for the DB15 connector.
Figure 2 shows an overview to OM-SE050ARD headers and connectors together with its
corresponding pin description.

OM-SE050ARD hardware overview
4 Jumpers overview
The OM-SE050ARD board uses individual jumpers to configure settings related with the
SE050 interfaces, power supply and power modes. This section provides an overview to
the OM-SE050ARD jumpers and its configuration options.
2
4.1 I C configuration
2
The OM-SE050ARD has jumpers that allow you to control the configuration of the I C
slave and master interfaces available in SE050. These jumpers are:
2
• J9, J10: Configures the I C master pull up connection.
2
• J15, J17: Configures the I C slave connection.
2
• J37, J38: Configures the I C slave interface pull up resistor.

4.3 Deep power-down mode
The deep power-down mode reduces the SE050 power consumption to the minimum. In
2
this mode, only I C pads stay supplied via Vin. The deep power-down mode is enabled by
setting the ENA pin to a logic zero. In addition, it is required to supply Vin pin and connect
Vout and Vcc pins at the PCB level.
The ENA pin controls an internal switch between Vout and Vin as shown in Figure 6.
Therefore, if Vout is connected to Vcc, the ENA pin can effectively switch the power on
and off to Vcc.
Figure 6. Deep power-down mode diagram
The jumpers J13 and J14 of the OM-SE050ARD allow you to control the SE050 deep
power-down mode. To enable the deep power-down mode using the OM-SE050ARD:
• J13: Must be set to position 2-3.
• J14: Must be set to position 3-4.
