The reader is able to access up to 8 antennas using an Intersil DG411 SPST analog switch for each antenna. Antenna selection is enabled by a CPLD that, based on the state of the SPI Chip Select signal, either sets one of the eight switch control lines or passes the SPI communication through to the reader IC. Each antenna has its own passive impedance matching circuit and EMI filter leading into the analog switch. A block diagram is shown below.

I.CODE1 Label IC is a dedicated 512 bit memory chip for electronic label applications such as detecting the presence of ink bag. RFID system operates in a so called “reader talks first” principle. The reader sends a command first, and the labels execute the instruction and send back their response to the buffer of the reader. Based on current Calgary structure, a RFID PCB board is designed to communicate with the Data Relay Card using the fourth SPI generic port. It is eventually intended to replace the third party board Smart RFID Multiplex Reader Board. There is only one single reader with five antennas and one CPLD on the PCB board. Due to current specific SPI interface is designed for the RFID board, the fourth SPI port cannot be used as a generic SPI communication port any more. CPLD is used to select which antenna will be communicated with the Reader. Serial data clock is 4.16MHz. The bit decoding of Label IC is fast mode with a 13.56Mhz carrier: each command consists of a start pulse (18.88us modulation), followed by one 8-bit instruction byte, five 8-bit parameter bytes, and two CRC bytes (16-bit CRC). The basic rules for software accessing Label IC is that software is required to first select antenna, switch on the RF, enable CRC16, force the RFID reader state machine back to idle, clear the reader buffer, and finally to set block start address and block numbers which software needs read/write data from/to the Label IC. Once software gets data back from the Label IC, software may need to issue a switch off RF command so as to reduce the interference from RFID board, except when software needs to hold the Label IC in selected condition. While the protocol allows for communication with multiple tags, collision detection and selection is not implemented. The reader will expect to communicate with the first tag that responds on each channel. rfid-hardware_REV5 CONFIDENTIAL Page 8 of 17 ENGINEERING SPECIFICATION DOCUMENT Project: CALGARY 2.1.1 I. CODE1 Label IC Memory Definition The 512 bit EEprom memory is divided into 16 blocks. A block is the smallest access unit. Each block consists of 4 bytes. Bit 0 in each byte represents the LSB (least significant bit) and bit 7 the MSB (most significant bit). The following table shows the definition for each block. Byte0 Block 0 Block 1 Block 2 Block 3 Block 4 Block 5 Block 6 Block 7 Block 8 Block 9 Block 10 Block 11 Block 12 Block 13 Block 14 Block 15 Byte1 Byte2 Byte3 SNR0 SNR4 F0 SNR1 SNR5 FF SNR2 SNR6 FF SNR3 SNR7 FF Serial Number Write Access Conditions Special Functions (EAS/QUIET) User Data User Data Figure 2.1 I.CODE1 Label ICs EEPROM Memory 2.1.2 Register Definition 1. Antenna Select Register There is only one single reader with five antennas (five Label ICs) on the PCB RFID board; hence the defined antenna select register is used to select which antenna will be communicated with data relay card (only one bit for each command is allowed to be active). Allow 1ms for switch settling time. Antenna Select Register Bit 7~5 RFU Antenna Antenna Antenna 2.

When writing data to the reader internal register, the following three data packets should be sent: First data packet: write 694 to register address Second data packet: write 696 to register data Third data packet: write 690 to 08 (write command) (2). When reading data from Reader internal register, the following three data packets should be sent: First data packet: write 692 to register address Second data packet: write 690 to 04 (read command) Third data packet: read register data from address 698 2.1.5 I.CODE1 Commands A selection of the Label IC is necessary for valid execution of the following commands: Selected Read Write Halt (Reserved for future use) Once an I.CODE1 Label IC is selected, it does not respond to the following command: Anticollision/Select Unselected Read The following commands work for both the selected and unselected states: EAS Reset QUIET Bit rfid-hardware_REV5 CONFIDENTIAL Page 11 of 17 ENGINEERING SPECIFICATION DOCUMENT Project: CALGARY After the Label IC has been selected, if the unselected command should be issued, you need to re-enter Label IC or switch off the RF. 2.1.6 Access Label IC memory Communication normally begins with the software sending a command and the Label IC responding. Commands always initiate a response except Reset Quiet Bit command. Some commands have prerequisite parameters such as memory read/write. Current RFID firmware code supports the following commands: Reset QUIET Bit Unselected Read Anticollision/Select Write Block X Selected Read EAS Test Manufacturer delivers the Label IC with the following configuration: (1) Serial number (block 0 and block 1) is unique, read only. (2) Write Access Conditions determine if blocks 3 through 15 can be accessed for writing. For Byte 0 in block 2: If set bit5 and bit4 to 1|1: Write access enabled. If set bit5 and bit4 to 0|0: Write access disabled. Be aware that writing of bit pairs 1|0 or 0|1 to block 2 is not allowed! Also the label must not be moved out of the communication field of the antenna during writing operation! (3) EAS test mode default setting is not defined. If you want to do an EAS test, you have to enable EAS test first by writing 1|1 to bit1 and bit0 in byte 0 of block 3. (4) Quiet mode default setting is not defined at delivery. Reset Quiet Bit command should be executed on the Label IC first, otherwise the Label IC does not respond to any command (except EAS command if the EAS mode is enabled) if the two bits (bit2 and bit3 in byte0 of block 3) are set to one (quiet mode is enabled). (5) Family Code/Application Identifier and User data memory is not defined. In order to implement the above commands, an antenna select command should be issued first by software so that hardware knows which antenna should be communicated, and the data packages (See appendix) should be sent by sequence. Since the internal register setting of the reader is similar for each command, firmware FPGA will implement these setting packages (A, B, C, D, E, F, J/I) automatically when it receives a command as described below from software. Also be aware that before you send a memory write command or an anticollision/select command, set Unselected Read command first, as the second byte of the serial number is used to calculate a quit value as a result of critical timing issue with SPI interface, this quit value is required when issuing an anticollision/select or memory write command. (1) Reset QUIET Bit rfid-hardware_REV5 CONFIDENTIAL Page 12 of 17 ENGINEERING SPECIFICATION DOCUMENT Project: CALGARY Action: QUIET bits are cleared for all I.CODE1 Label ICs in the antenna field, which are in QUIT mode. Parameters: None Commands: N package Response: None (2) Unselected Read Before issuing an unselected read command, software needs to set read block start address and the number of blocks first. The Label IC will respond with its required data bytes, which are stored to the buffer of the reader. Action: Each of the unselected I.CODE1 Label ICs responds with the requested number of block Parameters: Commands: Required block start address of data to be read Required number of blocks to be read G, K package Response: Data bits of X blocks, 16 bit CRC There are 16*32bit dual port block memory locations for latching the data read from the reader memory. After sending these packages, software needs to read the busy flag status from the PCI shadow memory address 6A8. Once this bit has been set to one, software needs to send a read data command (6A4) and immediately clear the busy flag. The read data command definition is as follows: Reading IC buffer data command (6A4) Bit 3~0 Read Command Block number Once this command has been sent, the firmware will read 32 bits word data from internal block memory to PCI shadow memory responding to this command. When PCI shadow memory address 6AA (BMEM UPDATED) has been set to one, software can get the 32bits data from PCI shadow memory address 69C, and also software is required to clear this bit (BMEM UPDATED) as well. For whole memory data read requires at least 25ms. (3) Anticollision/Select When firmware receives the serial numbers after issuing an Anticollision/Select command, it will transmit a QUIT byte immediately. The Label IC will remain in the timeslot chosen at this command for all further commands, such as memory write and selected read, until it leaves (and re-enters) the RF field. Action: Each of the unselected the Label IC responds with its 64 bits serial number in different timeslots Parameters: None rfid-hardware_REV5 CONFIDENTIAL Page 13 of 17 ENGINEERING SPECIFICATION DOCUMENT Project: CALGARY Commands: M package Response: 64 bit SNR (Serial Number), 16 bit CRC (4) Write Block X Remember that this command is required to a selection of the Label IC (Anticollision/Select). Before issuing a write command, software needs to set the block address and 4 bytes of data. Once each of the selected Label IC responds with its 64 bit serial number, firmware will send a quit value immediately so that the given 4 bytes of data are written to the address block if Label IC receives a QUIT from the reader in its timeslot. Action: Given 4 bytes of data are written to the address block if Label IC receives a QUIT from the reader in its timeslot. Parameters: Commands: Required block address of data to be written Required 4 bytes data to be written H, O package Response: 64 bit SNR (Serial Number), 16 bit CRC In addition, a minimum delay time of 4852.16 s (included in ‘total time*’) is required before the starting of a new command or switching off the RF due to EEPROM programming in Label IC. After software issuing a memory write command, firmware will send memory write done flag (6AE) to inform software, this flag means that firmware already finished sending a QUIT value to Label IC, therefore, the waiting time should be considered by software. Total time: 18.88 + 2416.64 + n * (325.68 + 3020.8 + 269.04 + 311.52) + 4852.16 = 7287.68 + n * 3927.04 s Here, n = number of timeslots (5) Selected Read The operation is similar to the Unselected Read except this command is required to a selection of the Label IC (Anticollision/Select). Each Label IC has his own antenna, and also the space between any two antennas is big enough to prevent from the interference among them, therefore this command is no necessary for current application. Action: Each of the selected the Label IC responds with the given number of blocks in its timeslot at which the Label IC was fixed with the Anticollision/ Select command Parameters: Required block start address of data to be read Required number of blocks to be read Commands: G, P package rfid-hardware_REV5 CONFIDENTIAL Page 14 of 17 ENGINEERING SPECIFICATION DOCUMENT Project: CALGARY Response: Data bits of X blocks, 16 bit CRC (6) EAS Test Once again, EAS test mode default setting is not defined by manufacture. Enable EAS test is required by writing 1|1 to bit1 and bit0 in byte 0 of block 3 before issuing EAS test. Action: I.CODE1 Label IC responds with a special predefined EAS pattern (256bits) Parameters: None Commands: Q package Response: 256 bit special EAS response After Label IC receives this command, the corresponding 32 bytes in hexadecimal notation as follows: 2F E8 82 F1 B3 B1 DA 9C 62 80 9A D1 70 38 86 12 D5 D2 6F A5 A7 81 AF 72 90 49 8B 37 7F 76 B0 EF 2.2.
