MFRC630 MFRC630 and MFRC630 plus: High-performance frontend for MIFARE and NTAG products Rev. 4.7 -- 12 September 2018 227547 1 Product data sheet COMPANY PUBLIC General description MFRC630 and MFRC630 plus, the high-performance frontend for MIFARE and NTAG products. The MFRC630 multi-protocol NFC frontend IC supports the following operating modes: * Read/write mode supporting ISO/IEC 14443A and MIFARE Classic * Read/write mode supporting NTAG The MFRC630's internal transmitter is able to drive a reader/writer antenna designed to communicate with ISO/IEC 14443A and MIFARE Cassic IC-based cards and transponders without additional active circuitry. The digital module manages the complete ISO/IEC 14443A framing and error detection functionality (parity and CRC). The MFRC630 supports MIFARE Classic with 1 kB memory, MIFARE Classic with 4 kB memory, MIFARE Ultralight, MIFARE Ultralight C, MIFARE Plus and MIFARE DESFire products. The MFRC630 supports higher transfer speeds of the MIFARE product family of up to 848 kbit/s in both directions. The following host interfaces are supported: * Serial Peripheral Interface (SPI) * Serial UART (similar to RS232 with voltage levels dependent on pin voltage supply) 2 * I C-bus interface (two versions are implemented: I2C and I2CL) The MFRC630 supports the connection of a secure access module (SAM). A dedicated 2 separate I C interface is implemented for a connection of the SAM. The SAM can be used for high secure key storage and acts as a very performant crypto coprocessor. A dedicated SAM is available for connection to the MFRC630. In this document the term MIFARE Classic card" refers to a MIFARE Classic IC-based contactless card.

All of the interrupts can be configured by firmware. Additionally, the firmware has possibilities to trigger interrupts or clear pending interrupt requests. Two 8-bit interrupt registers IRQ0 and IRQ1 are implemented, accompanied by two 8-bit interrupt enable registers IRQ0En and IRQ1En. A dedicated functionality of bit 7 to set and clear bits 0 to 6 in this interrupt controller registers is implemented. The MFRC630 indicates certain events by setting bit IRQ in the register Status1Reg and additionally, if activated, by pin IRQ. The signal on pin IRQ may be used to interrupt the host using its interrupt handling capabilities. This allows the implementation of efficient host software. Table 4. shows the available interrupt bits, the corresponding source and the condition for its activation. The interrupt bits Timer0IRQ, Timer1IRQ, Timer2IRQ, Timer3OIRQ, in register IRQ1 indicate an interrupt set by the timer unit. The setting is done if the timer underflows.

All rights reserved. 8 / 144 MFRC630 NXP Semiconductors MFRC630 and MFRC630 plus: High-performance frontend for MIFARE and NTAG products The TxIRQ bit in register IRQ0 indicates that the transmission is finished. If the state changes from sending data to transmitting the end of the frame pattern, the transmitter unit sets the interrupt bit automatically. The bit RxIRQ in register IRQ0 indicates an interrupt when the end of the received data is detected. The bit IdleIRQ in register IRQ0 is set if a command finishes and the content of the command register changes to idle. The register WaterLevel defines both - minimum and maximum warning levels - counting from top and from bottom of the FIFO by a single value. The bit HiAlertIRQ in register IRQ0 is set to logic 1 if the HiAlert bit is set to logic 1, that means the FIFO data number has reached the top level as configured by the register WaterLevel and bit WaterLevelExtBit. The bit LoAlertIRQ in register IRQ0 is set to logic 1 if the LoAlert bit is set to logic 1, that means the FIFO data number has reached the bottom level as configured by the register WaterLevel. The bit ErrIRQ in register IRQ0 indicates an error detected by the contactless UART during receive. This is indicated by any bit set to logic 1 in register Error. The bit LPCDIRQ in register IRQ0 indicates a card detected. The bit RxSOFIRQ in register IRQ0 indicates a detection of a SOF or a subcarrier by the contactless UART during receiving. The bit GlobalIRQ in register IRQ1 indicates an interrupt occurring at any other interrupt source when enabled.

Four timers -Timer0 to Timer3 - have an input clock that can be configured by register T(x)Control to be 13.56 MHz, 212 kHz, (derived from the 27.12 MHz quartz) or to be the underflow event of the fifth Timer (Timer4). Each timer implements a counter register which is 16 bit wide. A reload value for the counter is defined in a range of 0000h to FFFFh in the registers TxReloadHi and TxReloadLo. The fifth timer Timer4 is intended to be used as a wakeup timer and is connected to the internal LFO (Low Frequency Oscillator) as input clock source. The TControl register allows the global start and stop of each of the four timers Timer0 to Timer3. Additionally, this register indicates if one of the timers is running or stopped. Each of the five timers implements an individual configuration register set defining timer reload value (e.g. T0ReloadHi,T0ReloadLo), the timer value (e.g. T0CounterValHi, T0CounterValLo) and the conditions which define start, stop and clockfrequency (e.g. T0Control). The external host may use these timers to manage timing relevant tasks. The timer unit may be used in one of the following configurations: * * * * * Time-out counter Watch-dog counter Stop watch Programmable one-shot timer Periodical trigger The timer unit can be used to measure the time interval between two events or to indicate that a specific event has occurred after an elapsed time. The timer register content is modified by the timer unit, which can be used to generate an interrupt to allow an host to react on this event. The counter value of the timer is available in the registers T(x)CounterValHi, T(x)CounterValLo. The content of these registers is decremented at each timer clock. If the counter value has reached a value of 0000h and the interrupts are enabled for this specific timer, an interrupt will be generated as soon as the next clock is received. If enabled, the timer event can be indicated on the pin IRQ (interrupt request). The bit Timer(x)IRQ can be set and reset by the host controller. Depending on the configuration, the timer will stop counting at 0000h or restart with the value loaded from registers T(x)ReloadHi, T(x)ReloadLo. The counting of the timer is indicated by bit TControl.T(x)Running. The timer can be started by setting bits TControl.T(x)Running and TControl.T(x)StartStopNow or stopped by setting the bits TControl.T(x)StartStopNow and clearing TControl.T(x)Running. Another possibility to start the timer is to set the bit T(x)Mode.T(x)Start, this can be useful if dedicated protocol requirements need to be fulfilled.

If the configured stop event occurs before the Timer(x) underflows (e.g. a bit is received from the card), the timer unit stops (no interrupt is generated). If no stop event occurs, the timer unit continues to decrement the counter registers until the content is zero and generates a timer interrupt request at the next clock cycle. This allows to indicate to a host that the event did not occur during the configured time interval. 7.2.1.2 Wake-up timer The wake-up Timer4 allows to wakeup the system from standby after a predefined time. The system can be configured in such a way that it is entering the standby mode again in case no card had been detected. This functionality can be used to implement a low-power card detection (LPCD). For the low-power card detection it is recommended to set T4Control.T4AutoWakeUp and T4Control.T4AutoRestart, to activate the Timer4 and automatically set the system in standby. The internal low frequency oscillator (LFO) is then used as input clock for this Timer4. If a card is detected the host-communication can be started. If bit T4Control.T4AutoWakeUp is not set, the MFRC630 will not enter the standby mode again in case no card is detected but stays fully powered. 7.2.1.3 Stop watch The elapsed time between a configured start- and stop event may be measured by the MFRC630 timer unit. By setting the registers T(x)ReloadValueHi, T(x)reloadValueLo the timer starts to decrement as soon as activated. If the configured stop event occurs, the timers stops decrementing. The elapsed time between start and stop event can then be calculated by the host dependent on the timer interval TTimer: (1) If an underflow occurred which can be identified by evaluating the corresponding IRQ bit, the performed time measurement according to the formula above is not correct. 7.2.1.4 Programmable one-shot timer The host configures the interrupt and the timer, starts the timer and waits for the interrupt event on pin IRQ. After the configured time the interrupt request will be raised. 7.2.1.5 Periodical trigger If the bit T(x)Control.T(x)AutoRestart is set and the interrupt is activated, an interrupt request will be indicated periodically after every elapsed timer period.

The MFRC630 resets its interface and checks the current host interface type automatically having performed a power-up or resuming from power down. The MFRC630 identifies the host interface by the means of the logic levels on the control pins after the Cold Reset Phase. This is done by a combination of fixed pin connections.The following table shows the possible configurations defined by IFSEL1,IFSEL0: Table 7.Connection scheme for detecting the different interface types MFRC630 Product data sheet COMPANY PUBLIC 2 2 Pin Pin Symbol UART SPI I C I C-L 28 IF0 RX MOSI ADR1 ADR1 29 IF1 n.c.

The SPI clock SCK has to be generated by the master. Data communication from the master to the slave uses the Line MOSI. Line MISO is used to send data back from the MFRC630 to the master. A serial peripheral interface (SPI compatible) is supported to enable high speed communication to a host. The implemented SPI compatible interface is according to a standard SPI interface. The SPI compatible interface can handle data speed of up to 10 Mbit/s. In the communication with a host MFRC630 acts as a slave receiving data from the external host for register settings and to send and receive data relevant for the communication on the RF interface. NSS (Not Slave Select) enables or disables the SPI interface. When NSS is logical high, the interface is disabled and reset. Between every SPI command the NSS must go to logical high to be able to start the next command read or write. On both data lines (MOSI, MISO) each data byte is sent by MSB first. Data on MOSI line shall be stable on rising edge of the clock line (SCK) and is allowed to change on falling edge. The same is valid for the MISO line. Data is provided by the MFRC630 on the falling edge and is stable on the rising edge.The polarity of the clock is low at SPI idle. 7.4.2.2 Read data To read out data from the MFRC630 by using the SPI compatible interface the following byte order has to be used. The first byte that is sent defines the mode (LSB bit) and the address. Table 8.Byte Order for MOSI and MISO byte 0 byte 1 byte 2 byte 3 to n-1 byte n byte n+1 MOSI address 0 address 1 address 2 ........ address n 00h MISO X data 0 data 1 ........ data n - 1 data n Remark: The Most Significant Bit (MSB) has to be sent first.

The levels supplied to the pins are between VSS and PVDD. To achieve full compatibility of the voltage levels to the RS232 specification, a RS232 level shifter is required. Table 12 "Selectable transfer speeds" describes examples for different transfer speeds and relevant register settings. The resulting transfer speed error is less than 1.5 % for all described transfer speeds. The default transfer speed is 115.2 kbit/s. To change the transfer speed, the host controller has to write a value for the new transfer speed to the register SerialSpeedReg. The bits BR_T0 and BR_T1 define factors to set the transfer speed in the SerialSpeedReg. Table 11 "Settings of BR_T0 and BR_T1" describes the settings of BR_T0 and BR_T1.

A START condition is defined with a HIGH-to-LOW transition on the SDA line while SCL is HIGH. A STOP condition is defined with a LOW-to-HIGH transition on the SDA line while SCL is HIGH. The master always generates the START and STOP conditions. The bus is considered to be busy after the START condition. The bus is considered to be free again a certain time after the STOP condition. The bus stays busy if a repeated START (Sr) is generated instead of a STOP condition. In this respect, the START (S) and repeated START (Sr) conditions are functionally identical. Therefore, the S symbol will be used as a generic term to represent both the START and repeated START (Sr) conditions.

The number of transmitted bytes during one data transfer is unrestricted but shall fulfil the read/write cycle format. 2 7.4.4.5 I C Acknowledge An acknowledge at the end of one data byte is mandatory. The acknowledge-related clock pulse is generated by the master. The transmitter of data, either master or slave, releases the SDA line (HIGH) during the acknowledge clock pulse. The receiver shall pull down the SDA line during the acknowledge clock pulse so that it remains stable LOW during the HIGH period of this clock pulse. The master can then generate either a STOP (P) condition to stop the transfer, or a repeated START (Sr) condition to start a new transfer. A master-receiver shall indicate the end of data to the slave- transmitter by not generating an acknowledge on the last byte that was clocked out by the slave. The slavetransmitter shall release the data line to allow the master to generate a STOP (P) or repeated START (Sr) condition.

The second byte indicates the register address followed by up to n-data bytes. In case the address indicates the FIFO, in one frame all n-data bytes are written to the FIFO register address. This enables for example a fast FIFO access. 2 7.4.4.8 I C-register read access To read out data from a specific register address of the MFRC630 the host controller shall use the procedure: First a write access to the specific register address has to be performed as indicated in the following frame: 2 The first byte of a frame indicates the device address according to the I C rules. The second byte indicates the register address. No data bytes are added. The read/write bit shall be logic 0. Having performed this write access, the read access starts. The host sends the device address of the MFRC630. As an answer to this device address the MFRC630 responds with the content of the addressed register. In one frame n-data bytes could be read using the same register address. The address pointing to the register is incremented automatically (exception: FIFO register address is not incremented automatically). This enables a fast transfer of register content. The address pointer is incremented automatically and data is read from the locations [address], [address+1], [address+2]... [address+(n-1)] In order to support a fast FIFO data transfer, the address pointer is not incremented automatically in case the address is pointing to the FIFO.

This 2 logical interface fulfills the I C specification, but the rise/fall timings will not be compliant 2 2 to the I C standard. The I CL interface uses standard I/O pads, and the communication speed is limited to 5 MBaud. The protocol itself is equivalent to the fast mode protocol of 2 I C. The SCL levels are generated by the host in push/pull mode. The MFRC630 does not stretch the clock. During the high period of SCL the status of the line is maintained by a bus keeper. The address is 01010xxb, where the last two bits of the address can be defined by the application. The definition of this bits can be done by two options. With a pin, where the higher bit is fixed to 0 or the configuration can be defined via EEPROM.

Instead, a on chip buskeeper 2 is implemented in the MFRC630 for SDA of the I CL interface. This protocol is intended to be used for a point to point connection of devices over a short distance and does not support a bus capability.The driver of the pin must force the line to the desired logic voltage. To avoid that two drivers are pushing the line at the same time following regulations must be fulfilled: SCL: As there is no clock stretching, the SCL is always under control of the Master. SDA: The SDA line is shared between master and slave. Therefore the master and the slave must have the control over the own driver enable line of the SDA pin. The following rules must be followed: * In the idle phase the SDA line is driven high by the master * In the time between start and stop condition the SDA line is driven by master or slave when SCL is low. If SCL is high the SDA line is not driven by any device * To keep the value on the SDA line a on chip buskeeper structure is implemented for the line 7.4.5 SAM interface 7.4.5.1 SAM functionality The MFRC630 implements a dedicated I2C or SPI interface to integrate a MIFARE SAM (Secure Access Module) in a very convenient way into applications (e.g. a proximity reader). The SAM can be connected to the microcontroller to operate like a cryptographic coprocessor. For any cryptographic task, the microcontroller requests a operation from the SAM, receives the answer and sends it over a host interface (e.g. I2C, SPI) interface to the connected reader IC. The MIFARE SAM supports a optimized method to integrate the SAM in a very efficient way to reduce the protocol overhead. In this system configuration, the SAM is integrated between the microprocessor and the reader IC, connected by one interface to the reader IC and by another interface to the microcontroller. In this application the microcontroller accesses the SAM using the T=1 protocol and the SAM accesses the reader IC using an I2C interface. The I2C SAM address is always defined by EEPROM register. Default value is 0101100. As the SAM is directly communicating with reader IC, the communication overhead is reduced. In this configuration, a performance boost of up to 40% can be achieved for a transaction time. The MIFARE SAM supports applications using MIFARE product-based cards. For multi application purposes an architecture connecting the microcontroller additionally directly to the reader IC is recommended. This is possible by connecting the MFRC630 on one interface (SAM Interface SDA, SCL) with the MIFARE SAM AV2.6 (P5DF081XX/ T1AR1070) and by connecting the microcontroller to the S2C or SPI interface.

Both 2 2 interface options of the MFRC630, I C, I CL or SPI can be used for this purpose. The interface option of the SAM itself is configured by a host command sent from the host to the SAM. 2 The I CL interface is intended to be used as connection between two IC's over a short 2 distance. The protocol fulfills the I C specification, but does support a single device connected to the bus only. The SPI block for SAM connection is identical with the SPI host interface block. The pins used for the SAM SPI are described in Table 17. Table 18.SPI SAM connection SPI functionality PIN MISO SDA2 SCL SCL2 MOSI IFSEL1 NSS IFSEL0 7.4.6 Boundary scan interface The MFRC630 provides a boundary scan interface according to the IEEE 1149.1. This interface allows to test interconnections without using physical test probes. This is done by test cells, assigned to each pin, which override the functionality of this pin. To be able to program the test cells, the following commands are supported: Table 19.Boundary scan command MFRC630 Product data sheet COMPANY PUBLIC Value (decimal) Command Parameter in Parameter out 0 bypass - - 1 preload data (24) - 1 sample - data (24) 2 ID code (default) - data (32) 3 USER code - data (32) 4 Clamp - - All information provided in this document is subject to legal disclaimers.

There are three Inputs: Test Clock (TCK); Test Mode Select (TMS); Test Data Input (TDI) and one output Test Data Output (TDO). TCK and TMS are broadcast signals, TDI to TDO generate a serial line called Scan path. Advantage of this technique is that independent of the numbers of boundary scan devices the complete path can be handled with four signal lines. The signals TCK, TMS are directly connected with the boundary scan controller. Because these signals are responsible for the mode of the chip, all boundary scan devices in one scan path will be in the same boundary scan mode. 7.4.6.2 Test Clock (TCK) The TCK pin is the input clock for the module. If this clock is provided, the test logic is able to operate independent of any other system clocks. In addition, it ensures that multiple boundary scan controllers that are daisy-chained together can synchronously communicate serial test data between components. During normal operation, TCK is driven by a free-running clock. When necessary, TCK can be stopped at 0 or 1 for extended periods of time. While TCK is stopped at 0 or 1, the state of the boundary scan controller does not change and data in the Instruction and Data Registers is not lost. The internal pull-up resistor on the TCK pin is enabled. This assures that no clocking occurs if the pin is not driven from an external source. 7.4.6.3 Test Mode Select (TMS) The TMS pin selects the next state of the boundary scan controller. TMS is sampled on the rising edge of TCK. Depending on the current boundary scan state and the sampled value of TMS, the next state is entered. Because the TMS pin is sampled on the rising edge of TCK, the IEEE Standard 1149.1 expects the value on TMS to change on the falling edge of TCK. Holding TMS high for five consecutive TCK cycles drives the boundary scan controller state machine to the Test-Logic-Reset state. When the boundary scan controller enters the Test-Logic-Reset state, the Instruction Register (IR) resets to the default instruction, IDCODE. Therefore, this sequence can be used as a reset mechanism. The internal pull-up resistor on the TMS pin is enabled.

TDI is sampled on the rising edge of TCK and, depending on the current TAP state and the current instruction, presents this data to the proper shift register chain. Because the TDI pin is sampled on the rising edge of TCK, the IEEE Standard 1149.1 expects the value on TDI to change on the falling edge of TCK. The internal pull-up resistor on the TDI pin is enabled. 7.4.6.5 Test Data Output (TDO) The TDO pin provides an output stream of serial information from the IR chain or the DR chains. The value of TDO depends on the current TAP state, the current instruction, and the data in the chain being accessed. In order to save power when the port is not being used, the TDO pin is placed in an inactive drive state when not actively shifting out data. Because TDO can be connected to the TDI of another controller in a daisy-chain configuration, the IEEE Standard 1149.1 expects the value on TDO to change on the falling edge of TCK. 7.4.6.6 Data register According to the IEEE1149.1 standard there are two types of data register defined: bypass and boundary scan The bypass register enable the possibility to bypass a device when part of the scan path.Serial data is allowed to be transferred through a device from the TDI pin to the TDO pin without affecting the operation of the device. The boundary scan register is the scan-chain of the boundary cells. The size of this register is dependent on the command. 7.4.6.7 Boundary scan cell The boundary scan cell opens the possibility to control a hardware pin independent of its normal use case. Basically the cell can only do one of the following: control, output and input.

With Update-DR this address is taken over into the actual address. Register Access Write At the Capture-DR the address and the data is taken over from the DR. The data is copied into the internal register at the given address. 7.5 Buffer 7.5.1 Overview An 512 x 8-bit FIFO buffer is implemented in the MFRC630. It buffers the input and output data stream between the host and the internal state machine of the MFRC630. Thus, it is possible to handle data streams with lengths of up to 512 bytes without taking timing constraints into account. The FIFO can also be limited to a size of 255 byte. In this case all the parameters (FIFO length, Watermark...) require a single byte only for definition. In case of a 512 byte FIFO length the definition of this values requires 2 bytes. 7.5.2 Accessing the FIFO buffer When the -Controller starts a command, the MFRC630 may, while the command is in progress, access the FIFO-buffer according to that command. Physically only one FIFObuffer is implemented, which can be used in input and output direction. Therefore the Controller has to take care, not to access the FIFO buffer in a way that corrupts the FIFO data.

Consequently, the FIFOLevel bits are set to logic 0, the actually stored bytes are not accessible any more and the FIFO buffer can be filled with another 512 bytes (or 255 bytes if the bit FIFOSize is set to 1) again. 7.5.4 Status Information about the FIFO buffer The host may obtain the following data about the FIFO-buffers status: * Number of bytes already stored in the FIFO-buffer. Writing increments, reading decrements the FIFO level: FIFOLength in register FIFOLength (and FIFOControl Register in 512 byte mode) * Warning, that the FIFO-buffer is almost full: HiAlert in register FIFOControl according to the value of the water level in register WaterLevel (Register 02h bit [2], Register 03h bit[7:0]) * Warning, that the FIFO-buffer is almost empty: LoAlert in register FIFOControl according to the value of the water level in register WaterLevel (Register 02h bit [2], Register 03h bit[7:0]) * FIFOOvl bit indicates, that bytes were written to the FIFO buffer although it was already full: ErrIRQ in register IRQ0. WaterLevel is one single value defining both HiAlert (counting from the FIFO top) and LoAlert (counting from the FIFO bottom). The MFRC630 can generate an interrupt signal if: * LoAlertIRQEn in register IRQ0En is set to logic 1 it will activate pin IRQ when LoAlert in the register FIFOControl changes to 1. * HiAlertIRQEN in register IRQ0En is set to logic 1 it will activate pin IRQ when HiAlert in the register FIFOControl changes to 1. The bit HiAlert is set to logic 1 if maximum water level bytes (as set in register WaterLevel) or less can be stored in the FIFO-buffer. It is generated according to the following equation: (2) The bit LoAlert is set to logic 1 if water level bytes (as set in register WaterLevel) or less are actually stored in the FIFO-buffer. It is generated according to the following equation: (3) MFRC630 Product data sheet COMPANY PUBLIC All information provided in this document is subject to legal disclaimers.

An external circuit can be connected to the communication interface pins SIGIN and SIGOUT to modulate and demodulate the data. The contactless UART handles the protocol requirements for the communication schemes in co-operation with the host. The protocol handling itself generates bit- and byte-oriented framing and handles error detection like Parity and CRC according to the different contactless communication schemes. The size, the tuning of the antenna, and the supply voltage of the output drivers have an impact on the achievable field strength. The operating distance between reader and card depends additionally on the type of card used. 7.6.2 TX transmitter The signal delivered on pin TX1 and pin TX2 is the 13.56 MHz carrier modulated by an envelope signal for energy and data transmission. It can be used to drive an antenna directly, using a few passive components for matching and filtering, see Section 13 "Application information". The signal on TX1 and TX2 can be configured by the register DrvMode, see Section 8.8.1 "TxMode". The modulation index can be set by the TxAmp. Following figure shows the general relations during modulation influenced by set_clk_mode envelope TX ASK100 TX ASK10 (1) (2) 1: Defined by set_cw_amplitude. 2: Defined by set_residual_carrier. time 001aan355 Figure 20.General dependences of modulation Note: When changing the continuous carrier amplitude, the residual carrier amplitude also changes, while the modulation index remains the same.

It is activated when the value of TxFrameCon.DCodeType is set to 0000 (bin). The Bit-Generator encodes the data stream byte-wise and can apply the following encoding steps to each data byte. 1. Add a start-bit of specified type at beginning of every byte 2. Add a stop-bit and EGT bits of a specified type. The maximum number of EGT bit is 6, only full bits are supported 3. Add a parity-bit of a specified type 4. TxLastBits (skips a given number of bits at the end of the last byte in a frame) 5. Encrypt data-bit (MIFARE Classic encryption) It is not possible to skip more than 8 bit of a single byte! By default, data bytes are always treated LSB first. 7.6.3 Receiver circuitry 7.6.3.1 General The MFRC630 features a versatile quadrature receiver architecture with fully differential signal input at RXP and RXN. It can be configured to achieve optimum performance for reception of various 13.56 MHz based protocols. For all processing units various adjustments can be made to obtain optimum performance. 7.6.3.2 Block diagram Figure 23 shows the block diagram of the receiver circuitry. The receiving process includes several steps. First the quadrature demodulation of the carrier signal of 13.56 MHz is done. Several tuning steps in this circuit are possible.

In this case the Rcv_RX_single bit has to be set. In the single ended mode, the two receiver pins RXP and RXN need to be connected together and will provide a single ended signal to the receiver circuitry. When using the receiver in a single ended mode the receiver sensitivity is decreased and the achievable reading distance might be reduced, compared to the fully differential mode. Table 23.Configuration for single or differential receiver Mode rcv_rx_single pins RXP and RXN Fully differential 0 provide differential signal from differential antenna by separate rxcoupling branches Quasi differential 1 connect RXP and RXN together and provide single ended signal from antenna by a single rxcoupling branch The quadrature-demodulator uses two different clocks, Q-clock and I-clock, with a phase shift of 90 between them. Both resulting baseband signals are amplified, filtered, digitized and forwarded to a correlation circuitry. The typical application is intended to implement the Fully differential mode and will deliver maximum reader/writer distance. The Quasi differential mode can be used together with dedicated antenna topologies that allow a reduction of matching components at the cost of overall reading performance. During low power card detection the DC levels at the I- and Q-channel mixer outputs are evaluated. This requires that mixers are directly connected to the ADC. This can be configured by setting the bit Rx_ADCmode in register Rcv (38h). MFRC630 Product data sheet COMPANY PUBLIC All information provided in this document is subject to legal disclaimers.

A digital circuitry, comprising state machines, coder and decoder logic and an analog circuitry with the modulator and antenna drivers, receiver and amplification circuitry. For example, the interface between these two blocks can be configured in the way, that the interfacing signals may be routed to the pins SIGIN and SIGOUT. The most important use of this topology is the active antenna concept where the digital and the analog blocks are separated. This opens the possibility to connect e.g. an additional digital block of another MFRC630 device with a single analog antenna front-end.

This topology supports, that some parts of the analog part of the MFRC630 may be connected to the digital part of another device. The switch SigOutSel in registerSigOut can be used to measure signals. This is especially important during the design In phase or for test purposes to check the transmitted and received data. However, the most important use of SIGIN/SIGOUT pins is the active antenna concept. An external active antenna circuit can be connected to the digital circuit of the MFRC630.

These can be e.g. SOF or EOF symbols as they are used by the ISO14443 protocols or proprietary protocol symbols. Symbols are defined by means of the symbol definition registers and the mode registers. Four different symbols can be used. Two of them, Symbol0 and Symbol1 have a maximum pattern length of 16 bit and feature a burst length of up to 256 bits of either logic "0" or logic "1". The Symbol2 and Symbol3 are limited to 8 bit pattern length and do not support a burst. The definition of symbol patterns is done by writing the bit sequence of the pattern to the appropriate register. The last bit of the pattern to be sent is located at the LSB of the register. By setting the symbol length in the symbol-length register (TxSym10Len and TxSym32Len) the definition of the symbol pattern is completed. All other bits at bitposition higher than the symbol length in the definition register are ignored. (Example: length of Symbol2 = 5, bit7 and bit6 are ignored, bit5 to bit0 define the symbol pattern, bit5 is sent first) Which symbol-pattern is sent can be configured in the TxFrameCon register. Symbol0, Symbol1 and Symbol2 can be sent before data packets, Symbol1, Symbol2 and Symbol3 can be sent after data packets. Each symbol is defined by a set of registers. Symbols are configured by a pair of registers. Symbol0 and Symbol1 share the same configuration and Symbol2 and Symbol3 share the same configuration. The configuration includes setting of bit-clock- and subcarrier-frequency, as well as selection of the pulse type/length and the envelope type. 7.7 Memory 7.7.1 Memory overview The MFRC630 implements three different memories: EEPROM, FIFO and Registers. At startup, the initialization of the registers which define the behavior of the IC is performed by an automatic copy of an EEPROM area (read/write EEPROM section1 and section2, register reset) into the registers. The behavior of the MFRC630 can be changed by executing the command LoadProtocol, which copies a selected default protocol from the EEPROM (read only EEPROM section4, register Set Protocol area) into the registers. The read/write EEPROM section2 can be used to store any user data or predefined register settings. These predefined settings can be copied with the command "LoadRegister" into the internal registers. The FIFO is used as Input/Out buffer and is able to improve the performance of a system with limited interface speed. 7.7.2 EEPROM memory organization The MFRC630 has implemented a EEPROM non-volatile memory with a size of 8 kB.The EEPROM is organized in pages of 64 bytes.

Therefore stability of the clock frequency is an important factor for proper performance. To obtain highest performance, clock jitter has to be as small as possible. This is best achieved by using the internal oscillator buffer with the recommended circuitry.

All rights reserved. 44 / 144 MFRC630 NXP Semiconductors MFRC630 and MFRC630 plus: High-performance frontend for MIFARE and NTAG products 7.8.2 IntegerN PLL clock line The MFRC630 is able to provide a clock with configurable frequency at CLKOUT from 1 MHz to 24 MHz (PLL_Ctrl and PLL_DIV). There it can serve as a clock source to a microcontroller which avoids the need of a second crystal oscillator in the reader system. Clock source for the IntegerN-PLL is the 27.12 MHz crystal oscillator. Two dividers are determining the output frequency. First a feedback integer-N divider configures the VCO frequency to be N x fin/2 (control signal pll_set_divfb). As supported Feedback Divider Ratios are 23, 27 and 28, VCO frequencies can be 23 x fin / 2 (312 MHz), 27 x fin / 2 (366 MHz) and 28 x fin / 2 (380 MHz). The VCO frequency is divided by a factor which is defined by the output divider (pll_set_divout). Table 35 "Divider values for selected frequencies using the integerN PLL" shows the accuracy achieved for various frequencies (integer multiples of 1 MHz and some typical RS232 frequencies) and the divider ratios to be used. The register bit ClkOutEn enables the clock at CLKOUT pin. The following formula can be used to calculate the output frequency: fout = 13.56 MHz x PLLDiv_FB /PLLDiv_Out Table 36.Divider values for selected frequencies using the integerN PLL Frequency [MHz] 4 6 8 10 12 20 24 1.8432 3.6864 PLLDiv_FB 23 27 23 28 23 28 23 28 28 PLLDiv_Out 78 61 39 38 26 19 16 206 103 accuracy [%] 0.04 0.03 0.04 0.08 0.04 0.08 0.04 0.01 0.01 7.8.3 Low Frequency Oscillator (LFO) The MFRC630 implements an Low-Frequency Oscillator (LFO). Timer T4 can be configured to use a clock generated by this LFO as input clock, and can be configured as wakeup counter. As wakeup counter, the timer T4 allows to wake up the system in regular time intervals which allows to design a reader that is regularly polling for card presence or implements a low-power card detection (LPCD). The LFO is trimmed during chip production to run at 16 kHz. Unless a high accuracy of the LFO is required by the application, and the device is operated in an environment with changing ambient temperatures, trimming of the LFO is not required. For a typical application making use of the LFO for wake-up from power saving mode, the trim value set during production can be used. Optional trimming to achieve a higher accuracy of the 16 kHz LFO clock is supported by a digital state machine which compares LFO-clock to a reference clock generated by the connected 27.12Mhz crystal. As reference clock frequency for trimming of the LFO, a 13.56 MHz clock (27.12Mhz divided by 2 ) input clock to one of the timers T0,T1,T2 or T3 is used. One of the timers T0,T1,T2,T3 with an input clock of 13,56 MHz crystal clock is used to count one clock period of the LFO. For an LFO Clock running at 16KHz this would result in 848 wakeup timer clocks of timer Tx (T0, T1, T2, T3). Therefrore, the timer count value Tx at the end of a trimming cycle is expected to be 176 (wakeup timer is counting down: 1023-848=175, +/- 1 tolerance is accepted). The trim cycle is executed once in the T4 MFRC630 Product data sheet COMPANY PUBLIC All information provided in this document is subject to legal disclaimers.

Therefore the T4 autoload value shall be bigger than 0x05 to ensure that one trimming cycle takes place before T4 expires. The Tx timer value is reloaded to 1023 during the start of an Auto trim cycle. This happens every time, once after the T4 timer underflows. At the end of each trim cycle, the timer value is checked: * Timer Tx value < 174: LFO Frequency is too low and the trim value is incremented by 1 on T4 Timer event * Timer Tx value > 176: LFO Frequency is too high and the trim value is decremented by 1 on T4 Timer event * Timer Tx value is within 174 and 176: LFO Frequency = 16 KHz and trimming procedure is stopped The cycle proceeds until the autotrimm function is stopped (Timer Tx value is within 174 and 176). In addition, the trimming cycle can be aborted by sending an IDLE Command from the host to cancel the current command execution. T3 is not allowed to be used in case T4AutoLPCD is set in parallel. It is not required to configure a TXStart condition with underflow. The T0/1/2/3 timer will typically not underflow. It may happen if the LPO clock is very slow, but it is not required to take an action to generate this event. 7.9 Power management 7.9.1 Supply concept The MFRC630 is supplied by VDD (Supply Voltage), PVDD (Pad Supply) and TVDD (Transmitter Power Supply). These three voltages are independent from each other. To connect the MFRC630 to a Microcontroller supplied by 3.3 V, PVDD and VDD shall be at a level of 3.3 V, TVDD can be in a range from 3.3 V to 5.0 V. A higher supply voltage at TVDD will result in a higher field strength. Independent of the voltage it is recommended to buffer these supplies with blocking capacitances close to the terminals of the package. VDD and PVDD are recommended to be blocked with a capacitor of 100 nF min, TVDD is recommended to be blocked with 2 capacitors, 100 nF parallel to 1.0 F AVDD and DVDD are not supply input pins. They are output pins and shall be connected to blocking capacitors 470 nF each. 7.9.2 Power reduction mode 7.9.2.1 Power-down A hard power-down is enabled with HIGH level on pin PDOWN. This turns off the internal 1.8 V voltage regulators for the analog and digital core supply as well as the oscillator. All digital input buffers are separated from the input pads and clamped internally (except pin PDOWN itself). The output pins are switched to high impedance. HardPowerDown is performing a reset of the IC. All registers will be reset, the Fifo will be cleared. To leave the power-down mode the level at the pin PDOWN as to be set to LOW. This will start the internal start-up sequence. MFRC630 Product data sheet COMPANY PUBLIC All information provided in this document is subject to legal disclaimers.

All rights reserved. 46 / 144 MFRC630 NXP Semiconductors MFRC630 and MFRC630 plus: High-performance frontend for MIFARE and NTAG products 7.9.2.2 Standby mode The standby mode is entered immediately after setting the bit PowerDown in the register Command. All internal current sinks are switched off. Voltage references and voltage regulators will be set into stand-by mode. In opposition to the power-down mode, the digital input buffers are not separated by the input pads and keep their functionality. The digital output pins do not change their state. During standby mode, all registers values, the FIFO's content and the configuration itself will keep its current content. To leave the standby mode the bit PowerDown in the register Command is cleared. This will trigger the internal start-up sequence. The reader IC is in full operation mode again when the internal start-up sequence is finalized (the typical duration is 15 us). A value of 55h must be sent to the MFRC630 using the RS232 interface to leave the 2 standby mode. This is must at RS232, but cannot be used for the I C/SPI interface. Then read accesses shall be performed at address 00h until the device returns the content of this address. The return of the content of address 00h indicates that the device is ready to receive further commands and the internal start-up sequence is finalized. 7.9.2.3 Modem off mode When the ModemOff bit in the register Control is set the antenna transmitter and the receiver are switched off. To leave the modem off mode clears the ModemOff bit in the register Control. 7.9.3 Low-Power Card Detection (LPCD) The low-power card detection is an energy saving mode in which the MFRC630 is not fully powered permanently. The LPCD works in two phases. First the standby phase is controlled by the wake-up counter (WUC), which defines the duration of the standby of the MFRC630. Second phase is the detection-phase. In this phase the values of the I and Q channel are detected and stored in the register map. (LPCD_I_Result, LPCD_Q_Result).This time period can be handled with Timer3. The value is compared with the min/max values in the registers (LPCD_IMin, LPCD_IMax; LPCD_QMin, LPCD_QMax). If it exceeds the limits, a LPCDIRQ is raised. After the command LPCD the standby of the MFRC630 is activated, if selected. The wake-up Timer4 can activate the system after a given time. For the LPCD it is recommended to set T4AutoWakeUp and T4AutoRestart, to start the timer and then go to standby. If a card is detected the communication can be started. If T4AutoWakeUp is not set, the IC will not enter Standby mode in case no card is detected. 7.9.4 Reset and start-up time A 10 s constant high level at the PDOWN pin starts the internal reset procedure.

By writing a command-code to the command register the command is executed. Arguments and/or data necessary to process a command, are exchanged via the FIFO buffer. * Each command that needs a certain number of arguments will start processing only when it has received the correct number of arguments via the FIFO buffer. * The FIFO buffer is not cleared automatically at command start. It is recommended to write the command arguments and/or the data bytes into the FIFO buffer and start the command afterwards. * Each command may be stopped by the host by writing a new command code into the command register e.g.: the Idle-Command. 7.10.2 Command set overview Table 37.Command set Command No. Parameter (bytes) Short description Idle 00h - no action, cancels current command execution LPCD 01h - low-power card detection LoadKey 02h (keybyte1),(keybyte2), (keybyte3), (keybyte4), (keybyte5),(keybyte6); reads a MIFARE Classic key (size of 6 bytes) from FIFO buffer ant puts it into Key buffer MFAuthent 03h 60h or 61h, (block address), (card serial number byte0),(card serial number byte1), (card serial number byte2),(card serial number byte3); performs the MIFARE Classic authentication Receive 05h - activates the receive circuit Transmit 06h bytes to send: byte1, byte2,.... transmits data from the FIFO buffer Transceive 07h bytes to send: byte1, byte2,.... transmits data from the FIFO buffer and automatically activates the receiver after transmission finished MFRC630 Product data sheet COMPANY PUBLIC All information provided in this document is subject to legal disclaimers.

When the MFAuthent command is active, any FIFO access is blocked. Anyhow if there is an access to the FIFO, the bit WrErr in the Error register is set. This command terminates automatically when the MIFARE Classic card is authenticated and the bit MFCrypto1On is set to logic 1. This command does not terminate automatically, when the card does not answer, therefore the timer should be initialized to automatic mode. In this case, beside the bit IdleIRQ the bit TimerIRQ can be used as termination criteria. During authentication processing the bits RxIRQ and TxIRQ are blocked. The Crypto1On shows if the authentication was successful. The Crypto1On is always valid. In case there is an error during authentication, the bit ProtocolErr in the Error register is set to logic 1 and the bit Crypto1On in register Status2Reg is set to logic 0. 7.10.3.5 Receive command Command (05h); The MFRC630 activates the receiver path and waits for any data stream to be received, according to its register settings. The registers must be set before starting this command according to the used protocol and antenna configuration. The correct settings have to be chosen before starting the command. This command terminates automatically when the received data stream ends. This is indicated either by the end of frame pattern or by the length byte depending on the selected framing and speed. 7.10.3.6 Transmit command Command (06h); data to transmit The content of the FIFO is transmitted immediately after starting the command. Before transmitting the FIFO all relevant registers have to be set to transmit data. This command terminates automatically when the FIFO gets empty. It can be terminated by any other command written to the command register. 7.10.3.7 Transceive command Command (07h); data to transmit This command transmits data from FIFO buffer and automatically activates the receiver after a transmission is finished. Each transmission process starts by writing the command into CommandReg. Remark: If the bit RxMultiple in register RxModeReg is set to logic 1, this command will never leave the receiving state, because the receiving will not be cancelled automatically. 7.10.3.8 WriteE2 command Command (08h), Parameter1 (addressH), Parameter2 (addressL), Parameter3 (data); MFRC630 Product data sheet COMPANY PUBLIC All information provided in this document is subject to legal disclaimers.

In 512-byte FIFO mode, the register is extended by bit WaterLevelExtBit in the FIFOControl. This functionality can be used to avoid a FIFO buffer overflow or underflow: The bit HiAlert bit in FIFO Control is read logic 1, if the number of bytes in the FIFO-buffer is equal or less than the number defined by the waterlevel configuration. The bit LoAlert bit in FIFO control is read logic 1, if the number of bytes in the FIFO buffer is equal or less than the number defined by the waterlevel configuration.

Refer to Section 7.5 "Buffer". 8.6 Interrupt configuration registers The Registers IRQ0 register and IRQ1 register implement a special functionality to avoid the unintended modification of bits. The mechanism of changing register contents requires the following consideration: IRQ(x).Set indicates, if a set bit on position 0 to 6 shall be cleared or set. Depending on the content of IRQ(x).Set, a write of a 1 to positions 0 to 6 either clears or sets the corresponding bit. With this register the application can modify the interrupt status which is maintained by the MFRC630. Bit 7 indicates, if the intended modification is a setting or clearance of a bit. Any 1 written to a bit position 6...0 will trigger the setting or clearance of this bit as defined by bit 7. Example: writing FFh sets all bits 6..0, writing 7Fh clears all bits 6..0 of the interrupt request register 8.6.1 IRQ0 register Interrupt request register 0.

Note: If a collision is part of the defined EOF symbol, CollDet is not set to 1. 1 ProtErr A protocol error has occurred. A protocol error can be a wrong stop bit or SOF or a wrong number of received data bytes. When a protocol error is detected, data reception is stopped. Note: ProtErr is automatically cleared at start of a receive or transceive command. In case of a transceive command, it is cleared at the start of the receiving phase ("Wait for data" state). Note: When a protocol error occurs the last received data byte is not written into the FIFO. 0 IntegErr A data integrity error has been detected. Possible cause can be a wrong parity or a wrong CRC. In case of a data integrity error the reception is continued. Note: IntegErr is automatically cleared at start of a Receive or Transceive command.

For the T4AutoTrimm function, at least one timer (T0 to T3) has to be configured properly for trimming (T3 is not allowed if T4AutoLPCD is set in parallel). 4 T4AutoLPCD If set to one, the timer activates a low-power card detection sequence. If a card is detected an interrupt request is raised and the system remains active if enabled. If no card is detected the MFRC630 enters the Power down mode if enabled. The timer is automatically restarted (no gap). Timer 3 is used to specify the time where the RF field is enabled to check if a card is present.

The receiving circuit component values needs to be designed for operation with the MFRC630. A reuse of dedicated antenna designs done for other products without adaptation of component values will result in degraded performance. 13.1.1 EMC low pass filter The MIFARE product-based system operates at a frequency of 13.56 MHz. This frequency is derived from a quartz oscillator to clock the MFRC630 and is also the basis for driving the antenna with the 13.56 MHz energy carrier. This will not only cause emitted power at 13.56 MHz but will also emit power at higher harmonics. The international EMC regulations define the amplitude of the emitted power in a broad frequency range. Thus, an appropriate filtering of the output signal is necessary to fulfil these regulations. Remark: The PCB layout has a major influence on the overall performance of the filter.

All rights reserved. 106 / 144 MFRC630 NXP Semiconductors MFRC630 and MFRC630 plus: High-performance frontend for MIFARE and NTAG products 13.1.2 Antenna matching Due to the impedance transformation of the given low pass filter, the antenna coil has to be matched to a certain impedance. The matching elements C1 and C2 can be estimated and have to be fine tuned depending on the design of the antenna coil. The correct impedance matching is important to provide the optimum performance. The overall quality factor has to be considered to guarantee a proper ISO/IEC 14443 communication scheme. Environmental influences have to be considered as well as common EMC design rules. For details refer to the NXP application notes. 13.1.3 Receiving circuit The internal receiving concept of the MFRC630 makes use both side-bands of the subcarrier load modulation of the card response via a differential receiving concept (RXP, RXN). No external filtering is required. It is recommended to use the internally generated VMID potential as the input potential of pin RX. This DC voltage level of VMID has to be coupled to the Rx-pins via R2 and R4. To provide a stable DC reference voltage capacitances C4, C6 has to be connected between VMID and ground. Refer to Figure 31 Considering the (AC) voltage limits at the Rx-pins the AC voltage divider of R1 + C3 and R2 as well as R3 + C5 and R4 has to be designed. Depending on the antenna coil design and the impedance matching the voltage at the antenna coil varies from antenna design to antenna design. Therefore the recommended way to design the receiving circuit is to use the given values for R1(= R3), R2 (= R4), and C3 (= C5) from the above mentioned application note, and adjust the voltage at the RX-pins by varying R1(= R3) within the given limits. Remark: R2 and R4 are AC-wise connected to ground (via C4 and C6). 13.1.4 Antenna coil The precise calculation of the antenna coils' inductance is not practicable but the inductance can be estimated using the following formula. We recommend designing an antenna either with a circular or rectangular shape. (4) * I1 - Length in cm of one turn of the conductor loop * D1 - Diameter of the wire or width of the PCB conductor respectively * K - Antenna shape factor (K = 1,07 for circular antennas and K = 1,47 for square antennas) * L1 - Inductance in nH * N1 - Number of turns * Ln: Natural logarithm function The actual values of the antenna inductance, resistance, and capacitance at 13.56 MHz depend on various parameters such as: MFRC630 Product data sheet COMPANY PUBLIC All information provided in this document is subject to legal disclaimers.

This values stored in EEPROM can be used to configure the MFRC63003 with the command LoadReg.Typically, some of this entries will be required to be modified compared to the preset values to achieve the best RF performance for a specific antenna. The registers 0x28...0x39 are relevant for configuration of the Antenna. For each supported protocol, a dedicated preset configuration is available. To ensure compatibility between products of the CLRC66303 family, all products use the same default settings which are initialized in EEPROM, even if some of this protocols are not supported by the MFRC63003 product (e.g.ISO/IEC14443-B) and cannot be used. Alternatively, the registers can be initialized by individual register write commands.
