1. General information
1.1 Scope
This document describes the basic functionality and electrical specifications of the
Reader RD710.
The Reader RD710 is designed for use in development purposes as a hardware
reference design contactless reader. These reader is intended for use in connection with
PC to develop application software or other hardware, based on MFRC523 reader chip in
connection with a Cortex M3 LPC1768 µController.
1.2 General Description
The reader RD710 is a contactless Reader/Writer compliant to the ISO/IEC14443
standard and is able to handle data rates of 106kBit, 212kBit, 424kBit and 848kBit.
The RD710 is based on NXP MFRC523 and can be operated in connection with a
MIFARE SAM EV1. The SAM module can be used for key storage and enhanced crypto
operation to increase the security level.
It uses the NXP Cortex M3 LPC1768 µController. MFRC523 reader ICs is a highly
integrated reader IC solutions for contactless communication purposes at 13.56 MHz.
The reader RD710 is designed to work with an external AN700 antenna to achieve an
optimum reading performance for contactless applications.
It provides several communication interfaces on board such as: USB, RS232, RS485
(RS422), Ethernet (via LPC_ extension board), JTAG (a JTAG IEEE 1149.1 compliant
interface for debugging).
For information on availability of samples as well as documentation, please refer

3. RD710 Hardware description
Both hardware versions are described in the following chapters.
3.1 Overall Hardware RD710
An architectural overview of the RD710 is shown in Fig 2.
Fig 2.
Block schematic of contactless reader RD710 – inner frame includes the
standard configuration without extensions.
The microcontroller directly interfaces with its integrated peripherals to the host PC via
serial port, USB or Ethernet. The serial port with RS232 compatible levels is used for
downloading firmware; the JTAG port can also be used for downloading firmware and
debugging. The reader IC MFRC523 is either connected via SPI, I2C and UART
interface to the M3 Cortex microcontroller; this configuration is software selectable. The
SAM is directly connected to the microcontroller via an ISO/IEC 7816 interface with
setting T=1 protocol implemented in SW on the µC.
An additional amplifier enhances the RF output power to achieve high field strengths.
The amplifier is supplied by 5 Volts via USB bus power; the MFRC523 itself is only
capable of handling a 3.3 Volts supply which is directly generated onboard from
5 Volts USB bus power.
The RD710 reader is designed to use existing Pegoda RD701 housing with the AN710
Pegoda antenna. The AN710 antenna is connected via a 10-pin header to the RM710
board.

3.1.1
Plugging SAM RD710
The RD710 is able to work with a SAM in a PCM module (SIM card shape) for data
encryption/decryption and key storage. Therefore a SIM socket is assembled on the
PCB. This socket is accessible by opening the reader housing. The SAM can be used in
S- and X- configuration as shown in fig.1. The change from S- to X-configuration is done
via DIP switches.
3.1.2
Reader IC RD710
The RD710 contact less reader is equipped with a NXP IC MFRC523.

3.2.1.1
USB 2.0 Serial Port
The USB port is the default interface and always present on the RD710 board. The
supported standard is USB 2.0 (full speed; 12 Mbit).
The PC delivers a power supply voltage of 5V DC (max. 500mA) via USB interface. A
secondary boot loader in the firmware enables the readers USB port for an easy
firmware update.
USB connection and power supply filtering are given in Fig 4. The power supply of 5V
DC is filtered via inductance L1. A protection is implemented via diode D9. If an external
power of 5V DC on the 10-pin header is present, diode D9 prevents the USB bus to be
supplied out of the reader device.
The IP4220CZ6 is incorporated to protect the USB 2.0 port (communication lines D- and
D+) from ESD.

Two Serial Ports
One RS232 serial communication ports is wired out onto the 10-pin header COM; the
second serial port is brought out to the MEC6 connector. The supported communication
baud rates are: up to 115 200 bps.
The COM connector (10-pin header) is intended for serial communication with external
devices via RS232 interface. One RS232 serial ports (with all handshake and control
signals) is available on the 10-pin header. The +5V Power supply is also present on the
10-pin header to be able to supply reader RD710 without an USB connection (use as
power supply input) or to supply an external device with 5 Volts (use as power supply
output - max. current 200mA* due to USB power specification).
The second serial port is connected to the MEC6 port (only the signals RxD, TxD and
GND).
The primary boot loader uses the RS232 COM port for ISP programming in conjunction
with an external downloading program on the PC (NXP recommends Flash Magic).

DIP Switches
Both readers are sharing the same DIP switch configuration for setting some reader
parameter like LEDs connection, RESET key and beeper driving.
Eight DIP switches are used to set different configurations for reader RD710 (like reader
operation mode, SAM mode, different communication modes). The function of the
dedicated DIP switch is determined within the firmware which is programmed into the
microcontroller’s flash memory. All DIP switch functions for the default software, which is
originally delivered with the reader device, are described in detail in the SW design
report. The ON/OFF position of DIP switches is shown in Table 7.

There are eight DIP switches on the reader and their functionality is described in Table 7.

RF Amplifier with 5 Volts Supply
The RF booster amplifier circuit is similar for both reader ICs – for MFRC523. Due to 3.3
V TVDD supply limitation on the reader ICs two high speed MOSFET drivers are used for
increasing the output power on the AN710 antenna. The RF amplifier is supplied from the
5 V USB bus power.
The antenna is matched in regard to output power and compliancy to ISO/IEC 14443A
limits for baud rates from 106 kbps to 848 kpbs.

5 Volts Power Supply
The RM710 board is using a 5 V DC external power supply. The default configuration is
powering the device over the USB port. The additional possibility is applying a 5 V supply
to the dedicated power pin at the 10-pin header (COM).
The 5 V DC supply voltage from the personal computers USB port is filtered via
inductance L1.

Internal 3.3 V Power Supply
The internal 3.3 V power supply for the microcontroller, the reader ICs and some other
components is derived from IC5, a LP3961-3.3 linear voltage regulator. All additional
components for filtering and stabilizing the voltage regulator follow the recommendations
described in the datasheet of the LP3961-3.3. The input voltage of 5 V DC is regulated
down to a stabilized 3.3 V DC for supplying the reader IC and the microcontroller.

Reset Circuit
A reset switch (RESET) and External Reset line (/MRST) are attached to the same reset

Antenna AN710
The AN710 antenna has the same form factor as the antenna used in the existing AN700
Pegoda reader and it is directly connected to the 10-pin antenna header. The antenna in
combination with the main board (RM710) builds up the complete matching circuit and is
tuned for optimum performance.
Note that part of the matching components is placed on the antenna. Exchanging
antennas AN710 with AN700 (antenna of previous Pegoda) will result in antenna
mismatch and reduced reading performance.
An additional connector for attaching an active antenna to the RD710 reader is provided
(5-pin header active antenna) on the PCB to be able to easily implement different reader
architectures. In this case the modulation input and output of the reader IC MFRC523 is
accessible at this pin header.

Mechanical Requirements
The PCB boards RM710 fits into the current RD701 Pegoda housing. Therefore the
maximum outer dimension of the PCB board is limited to 72 x 72 mm.
The RM710 board includes an extension connector MEC6 for the HITEX LPC-COM
board at the same mechanical position. Additionally all other mechanical requirements
for a reuse of the RD 701 housing are considered. These requirements are:
•
The positions of the USB connector
•
The position of the mounting screws
•
The position of the antenna connection
•
Height of components on the PCB

3.2.7
Electrical Requirements
The board is USB bus powered. This requires a limitation of the maximum power
consumption below of 2.5 Watts at rated 5 volts supply, which corresponds to a
maximum of 500 mA supply current over the USB connection. The reader is designed to
work in a range of 4.75 to 5.25 Volts and to stay fully functional within this range. The
typical power consumption (without an additional LPC_COM board) is 170 mA.
