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.

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. Fig 4. Reader RD710 USB Port (extraction of schematic) Table 2.

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). Fig 5. RS232 port with pinout Table 3.

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. Fig 16.
