7.1 Interrupt controller
The interrupt controller handles the enabling/disabling of interrupt requests. 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 SLRC610 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.
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.

7.2 Timer module
Timer module overview
The SLRC610 implements five timers. 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.

7.2.1 Timer modes
7.2.1.1
Time-Out- and Watch-Dog-Counter
Having configured the timer by setting register T(x)ReloadValue and starting the counting
of Timer(x) by setting bit TControl.T(x)StartStop and TControl.T(x)Running, the timer unit
decrements the T(x)CounterValue Register beginning with the configured start event. 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 SLRC610 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
SLRC610 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:
 T  Treload
value
 Timer
value
 * T Timer
(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.

7.4 Host interfaces
7.4.1 Host interface configuration
The SLRC610 supports direct interfacing of various hosts as the SPI, I2C, I2CL and serial
UART interface type. The SLRC610 resets its interface and checks the current host
interface type automatically having performed a power-up or resuming from power down.
The SLRC610 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:

Connection to host with SPI
The SLRC610 acts as a slave during the SPI communication. 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 SLRC610 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 SLRC610 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 SLRC610 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 SLRC610 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.

7.4.3 RS232 interface
7.4.3.1
Selection of the transfer speeds
The internal UART interface is compatible to a RS232 serial interface. 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 14 “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 13 “Settings of BR_T0 and BR_T1” describes the settings of BR_T0 and BR_T1.

7.4.4 I2C-bus interface
7.4.4.1
General
An Inter IC (I2C) bus interface is supported to enable a low cost, low pin count serial bus
interface to the host. The implemented I2C interface is mainly implemented according the
NXP Semiconductors I2C interface specification, rev. 3.0, June 2007. The SLRC610 can
act as a slave receiver or slave transmitter in standard mode, fast mode and fast mode
plus.
The following features defined by the NXP Semiconductors I2C interface specification,
rev. 3.0, June 2007 are not supported:
• The SLRC610 I2C interface does not stretch the clock
• The SLRC610 I2C interface does not support the general call. This means that the
SLRC610 does not support a software reset
• The SLRC610 does not support the I2C device ID
• The implemented interface can only act in slave mode. Therefore no clock generation
and access arbitration is implemented in the SLRC610.
• High speed mode is not supported by the SLRC610

Fig 10. I2C-bus interface
The voltage level on the I2C pins is not allowed to be higher than PVDD.
SDA is a bidirectional line, connected to a positive supply voltage via a pull-up resistor.
Both lines SDA and SCL are set to HIGH level if no data is transmitted. Data on the
I2C-bus can be transferred at data rates of up to 400 kbit/s in fast mode, up to 1 Mbit/s in
the fast mode+.
If the I2C interface is selected, a spike suppression according to the I2C interface
specification on SCL and SDA is automatically activated.
For timing requirements refer to Table 196 “I2C-bus timing in fast mode and fast mode
plus”
7.4.4.2
I2C Data validity
Data on the SDA line shall be stable during the HIGH period of the clock. The HIGH state
or LOW state of the data line shall only change when the clock signal on SCL is LOW.

7.4.4.3
I2C START and STOP conditions
To handle the data transfer on the I2C-bus, unique START (S) and STOP (P) conditions
are defined.
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.

I2C 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 slave-transmitter
shall release the data line to allow the master to generate a STOP (P) or repeated START
(Sr) condition.

Alternatively the I2C address can be configured in the EEPROM. Several address
numbers are reserved for this purpose. During device configuration, the designer has to
ensure, that no collision with these reserved addresses in the system is possible. Check
the corresponding I2C specification for a complete list of reserved addresses.
For all SLRC610 devices the upper 5 bits of the device bus address are reserved by NXP
and set to 01010(bin). The remaining 2 bits (ADR_2, ADR_1) of the slave address can be
freely configured by the customer in order to prevent collisions with other I2C devices by
using the interface pins (refer to Table 8) or the value of the I2C address EEPROM register
(refer to Table 30).

I2C-register write access
To write data from the host controller via I2C to a specific register of the SLRC610 the
following frame format shall be used.
The read/write bit shall be set to logic 0.
The first byte of a frame indicates the device address according to the I2C rules. 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.
7.4.4.8
I2C-register read access
To read out data from a specific register address of the SLRC610 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:
The first byte of a frame indicates the device address according to the I2C 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 SLRC610. As an answer to this device address the SLRC610 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.

I2CL-bus interface
The SLRC610 provides an additional interface option for connection of a SAM. This
logical interface fulfills the I2C specification, but the rise/fall timings will not be compliant to
the I2C standard. The I2CL 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
I2C. The SCL levels are generated by the host in push/pull mode. The RC610 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. Refer to the
EEPROM configuration in Section 7.7.

The pull-up resistor is not required for the I2CL interface. Instead, a on chip buskeeper is
implemented in the SLRC610 for SDA of the I2CL 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 SLRC610 implements a dedicated I2C or SPI interface to integrate a 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
co-processor. 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.
7.4.5.2
SAM connection
The SLRC610 provides an interface to connect a SAM dedicated to the SLRC610. Both
interface options of the SLRC610, I2C, I2CL 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.
The I2CL interface is intended to be used as connection between two IC’s over a short
distance. The protocol fulfills the I2C 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 19.

7.4.6 Boundary scan interface
The SLRC610 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:

The Standard IEEE 1149.1 describes the four basic blocks necessary to use this interface:
Test Access Port (TAP), TAP controller, TAP instruction register, TAP data register;
7.4.6.1
Interface signals
The boundary scan interface implements a four line interface between the chip and the
environment. 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.

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.
7.4.6.4
Test Data Input (TDI)
The TDI pin provides a stream of serial information to the IR chain and the DR chains. 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.

7.5
Buffer
7.5.1 Overview
An 512  8-bit FIFO buffer is implemented in the SLRC610. It buffers the input and output
data stream between the host and the internal state machine of the SLRC610. 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 SLRC610 may, while the command is in
progress, access the FIFO-buffer according to that command. Physically only one
FIFO-buffer 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.
7.5.3 Controlling the FIFO buffer
Besides writing to and reading from the FIFO buffer, the FIFO-buffer pointers might be
reset by setting the bit FIFOFlush in FIFOControl to 1. 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 SLRC610 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 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:

7.6 Analog interface and contactless UART
7.6.1 General
The integrated contactless UART supports the external host online with framing and error
checking of the protocol requirements up to 848 kbit/s. 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.

Overshoot protection
The SLRC610 provides an overshoot protection for 100% ASK to avoid overshoots during
a PCD communication. Therefore two timers overshoot_t1 and overshoot_t2 can be used.
During the timer overshoot_t1 runs an amplitude defined by set_cw_amplitude bits is
provided to the output driver. Followed by an amplitude denoted by set_residual_carrier
bits with the duration of overshoot_t2.

Bit generator
The default coding of a data stream is done by using the Bit-Generator. 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. TxFirstBits (skips a given number of bits at the beginning of the first byte in a frame)
5. TxLastBits (skips a given number of bits at the end of the last byte in a frame)
6. Encrypt data-bit (MIFARE encryption)
TxFirstBits and TxLastBits can be used at the same time. If only a single data byte is sent,
it must be ensured that the range of TxFirstBits and TxLastBits do not overlap. It is not
possible to skip more than 8 bit of a single byte! ( (8 - TxFirstBits) + (8 - TxLastBits) ) < 8
By default, data bytes are always treated LSB first. To make use of a MSB first coding, the
TxMSBFirst in the register CLCON1 needs to be set.
7.6.3 Receiver circuitry

General
The SLRC610 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.

The receiver can also be operated in a single ended mode. 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.

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).
7.6.4 Active antenna concept
Two main blocks are implemented in the SLRC610. 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 SLRC610 device with a
single analog antenna front-end.

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 (see Figure 23 “Overview
SIGIN/SIGOUT Signal Routing”).
This topology supports, that some parts of the analog part of the SLRC610 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 SLRC610.
SigOutSel has to be configured in that way that the signal of the internal Miller Coder is
sent to SIGOUT pin (SigOutSel = 4). SigInSel has to be configured to receive Manchester
signal with sub-carrier from SIGIN pin (SigInSel = 1).
It is possible, to connect a passive antenna to pins TX1, TX2 and RX (via the appropriate
filter and matching circuit) and at the same time an active antenna to the pins SIGOUT
and SIGIN. In this configuration, two RF-parts may be driven (one after another) by a
single host processor.

7.6.5 Symbol generator
The symbol generator is used to create various protocol symbols like the CS symbol as
used by the ICODE EPC protocol.
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
bit-position 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 SLRC610 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 SLRC610 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 SLRC610 has implemented a EEPROM non-volatile memory with a size of 8 kB.The
EEPROM is organized in pages of 64 bytes. One page of 64 bytes can be programmed at
a time. Defined purposes had been assigned to specific memory areas of the EEPROM,
which are called Sections. Five sections 0..4 with different purpose do exist.

7.7.3 EEPROM initialization content LoadProtocol
The SLRC610 EEPROM is initialized at production with values which are used to reset
certain registers of the SLRC610 to default settings by copying the EEprom content to the
registers. Only registers or bits with “read/write” or “dynamic” access rights are initialized
with this default values copied from the EEProm.
Note that the addresses used for copying reset values from EEprom to registers are
dependent on the configured protocol and can be changed by the user.

7.8 Clock generation
7.8.1 Crystal oscillator
The clock applied to the SLRC610 acts as time basis for generation of the carrier sent out
at TX and for the quadrature mixer I and Q clock generation as well as for the coder and
decoder of the synchronous system. 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.

7.8.2 IntegerN PLL clock line
The SLRC610 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  fin/2 (control signal pll_set_divfb). As supported
Feedback Divider Ratios are 23, 27 and 28, VCO frequencies can be
23  fin / 2 (312 MHz), 27  fin / 2 (366 MHz) and 28  fin / 2 (380 MHz).
The VCO frequency is divided by a factor which is defined by the output divider
(pll_set_divout). Table 37 “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:

7.8.3 Low Frequency Oscillator (LFO)
The Low-Frequency (LFO) is implemented to drive a wake-up counter (WUC). This wakes
up the system in regular time intervals and eases the design of a reader that is regularly
polling for card presence or implements a low-power card detection.
The LFO is trimmed during 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 down, 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. As reference clockfrequency the 13.56 MHz crystal clock is available.

7.9 Power management
7.9.1 Supply concept
The SLRC610 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 SLRC610 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.
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 SLRC610 using the RS232 interface to leave the
standby mode. This is must at RS232, but cannot be used for the I2C/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.

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 SLRC610 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 SLRC610. 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 SLRC610 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.
The following figure shows the internal voltage regulator:

When the SLRC610 has finished the reset phase and the oscillator has entered a stable
working condition the IC is ready to be used. A typical duration before the IC is ready to
receive commands after the reset had been released is 2.5ms.

7.10 Command set
7.10.1 General
The behavior is determined by a state machine capable to perform a certain set of
commands. 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.

7.10.3 Command functionality
7.10.3.1
Idle command
Command (00h);
This command indicates that the SLRC610 is in idle mode. This command is also used to
terminate the actual command.
7.10.3.2
LPCD command
Command (01h);
This command performs a low-power card detection and/or an automatic trimming of the
LFO. After wakeup from standby, the values of the sampled I and Q channels are
compared with the min/max threshold values in the registers. If it exceeds the limits, an
LPCD_IRQ will be raised. After the LPCD command the standby is activated, if selected.
7.10.3.3
AckReq command
Command (04h);
Performs a Query (Full command must be written into the FIFO); a Ack and a ReqRn
command. All answers to the command will be written into the FIFO. The error flag is
copied after the answer into the FIFO.
This command terminates automatically and the then active state is idle.
7.10.3.4
Receive command
Command (05h);
The SLRC610 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.
Remark: If the bit RxMultiple in the RxModeReg register is set to logic 1, the Receive
command does not terminate automatically. It has to be terminated by activating any other
command in the CommandReg register (see Section 0.2.6 “RxMod”).
7.10.3.5
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.

7.10.3.6
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.
7.10.3.7
WriteE2 command
Command (08h), Parameter1 (addressH), Parameter2 (addressL), Parameter3 (data);
This command writes one byte into the EEPROM. If the FIFO contains no data, the
command will wait until the data is available.
Abort condition: Address-parameter outside of allowed range 0x00 – 0x7F.
7.10.3.8
WriteE2PAGE command
Command (09h), Parameter1 (page address), Parameter2..63 (data0, data1...data63);
This command writes up to 64 bytes into the EEPROM. The addresses are not allowed to
wrap over a page border. If this is the case, this additional data be ignored and stays in the
fifo. The programming starts after 64 bytes are read from the FIFO or the FIFO is empty.
Abort condition: Insufficient parameters in FIFO; Page address parameter outside of
range 0x00 – 0x7F.
7.10.3.9
ReadE2 command
Command (0Ah), Parameter1 (addressH), Parameter2 (addressL), Parameter3 (length);
Reads up to 256 bytes from the EEPROM to the FIFO. If a read operation exceeds the
address 1FFFh, the read operation continues from address 0000h.
Abort condition: Insufficient parameter in FIFO; Address parameter outside of range.
7.10.3.10
LoadReg command
Command (0Ch), Parameter1 (EEPROM addressH),Parameter2 (EEPROM addressL),
Parameter3 (RegAdr), Parameter4 (number);
Read a defined number of bytes from the EEPROM and copies the value into the Register
set, beginning at the given address RegAdr.
Abort condition: Insufficient parameter in FIFO; Address parameter outside of range.
7.10.3.11
LoadProtocol command
Command (0Dh), Parameter1 (Protocol number RX), Parameter2 (Protocol number TX);
Reads out the EEPROM Register Set Protocol Area and overwrites the content of the Rxand Tx- related registers. These registers are important for a Protocol selection.
Abort condition: Insufficient parameter in FIFO

8. SLRC610 registers
8.1 Register bit behavior
Depending on the functionality of a register, the access conditions to the register can vary.
In principle, bits with same behavior are grouped in common registers. The access
conditions are described in Table 41.
Table 41.
Behavior of register bits and their designation
Abbreviation Behavior
Table 42.
Address
Description
r/w
read and write These bits can be written and read via the host interface. Since
they are used only for control purposes, the content is not
influenced by the state machines but can be read by internal state
machines.
dy
dynamic
These bits can be written and read via the host interface. They
can also be written automatically by internal state machines, for
example Command register changes its value automatically after
the execution of the command.
r
read only
These register bits indicates hold values which are determined by
internal states only.
w
write only
Reading these register bits always returns zero.
RFU
-
These bits are reserved for future use and must not be changed.
In case of a required write access, it is recommended to write a
logic 0.

WaterLevelBits
Sets a level to indicate a FIFO-buffer state which can be read from
bits HighAlert and LowAlert in the FifoControl. 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.

8.5 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 SLRC610.
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

RxAlign
Used for reception of bit oriented frames: RxAlign defines the bit position
length for the first bit received to be stored. Further received bits are
stored at the following bit positions.
Example:
RxAlign = 0h - the LSB of the received bit is stored at bit 0, the second
received bit is stored at bit position 1.
RxAlign = 1h - the LSB of the received bit is stored at bit 1, the second
received bit is stored at bit position 2.
RxAlign = 7h - the LSB of the received bit is stored at bit 7, the second
received bit is stored in the following byte at position 0.
Note: If RxAlign = 0, data is received byte-oriented, otherwise
bit-oriented.

NoColl
If this bit is set, a collision will result in an IntegErr

RxLastBits
Defines the number of valid bits of the last data byte received in
bit-oriented communications. If zero the whole byte is valid.
Note: These bits are set by the RxDecoder in a bit-oriented
communication at the end of the communication. They are reset at start
of reception.

CollPos
These bits show the bit position of the first detected collision in a received
frame (only data bits are interpreted). CollPos can only be displayed for the
first 8 bytes of a data stream.
Example:
00h indicates a bit collision in the 1st bit
01h indicates a bit collision in the 2nd bit
08h indicates a bit collision in the 9th bit (1st bit of 2nd byte)
3Fh indicates a bit collision in the 64th bit (8th bit of the 8th byte)
These bits shall only be interpreted in ISO/IEC 15693/ICODE SLI read/write
mode if bit CollPosValid is set.
Note: If RxBitCtrl.RxAlign is set to a value different to 0, this value is included
in the CollPos.
Example: RxAlign = 4h, a collision occurs in the 4th received bit (which is the
last bit of that UID byte). The CollPos = 7h in this case.

T4AutoTrimm
If set to one, the timer activates an LFO trimming procedure when it
underflows. 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 SLRC610
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. Therefor you may not
use Timer 3 for T4AutoTrimm in parallel.
3
T4AutoRestart
Set to logic 1, the timer automatically restarts its countdown from
T4ReloadValue, after the counter value has reached the value zero.
Set to logic 0 the timer decrements to zero and stops. The bit
Timer4IRQ is set to logic 1 at timer underflow.
2
T4AutoWakeUp If set, the SLRC610 wakes up automatically, when the timer T4 has
an underflow. This bit has to be set if the IC should enter the Power
down mode after T4AutoTrimm and/or T4AutoLPCD is finished and
no card has been detected. If the IC should stay active after one of
these procedures this bit has to be set to 0.

operated in open drain, push-pull, at high impedance or pulled to a fix
high or low level.
8.8.2 TxAmp
With the set_cw_amplitude register output power can be traded off against power supply
rejection. Spending more headroom leads to better power supply rejection ration and
better accuracy of the modulation degree.
With CwMax set, the voltage of TX1 will be pulled to the maximum possible. This register
overrides the settings made by set_cw_amplitude.

8.13.1 SerialSpeed
This register allows to set speed of the RS232 interface. The default speed is set to
9,6kbit/s. The transmission speed of the interface can be changed by modifying the
entries for BR_T0 and BR_T1. The transfer speed can be calculated by using the
following formulas:
BR_T0 = 0: transfer speed = 27.12 MHz / (BR_T1 + 1)
BR_T0 > 0: transfer speed = 27.12 MHz / (BR_T1 + 33) / 2^(BR_T0  1)
The framing is implemented with 1 startbit, 8 databits and 1 stop bit. A parity bit is not
used. Transfer speeds above 1228,8 kbit/s are not supported.

Fig 29. Typical application antenna circuit diagram
13.1 Antenna design description
The matching circuit for the antenna consists of an EMC low pass filter (L0 and C0), a
matching circuitry (C1 and C2), and a receiving circuits (R1 = R3, R2 = R4, C3 = C5 and
C4 = C6;), and the antenna itself. The receiving circuit component values needs to be
designed for operation with the SLRC610. A reuse of dedicated antenna designs done for
other products without adaptation of component values will result in degraded
performance.
For a more detailed information about designing and tuning the antenna, please refer to
the relevant application notes:
• MICORE reader IC family; Directly Matched Antenna Design, Ref. 1 and
• MIFARE (14443A) 13.56 MHz RFID Proximity Antennas, Ref. 2.
13.1.1 EMC low pass filter
The MIFARE system operates at a frequency of 13.56 MHz. This frequency is derived
from a quartz oscillator to clock the SLRC610 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.
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 SLRC610 makes use both side-bands of the
sub-carrier 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 29
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.

1 8
L 1 = 2  I 1   ln  ------ – K N 1



• 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:
•
•
•
•
•
antenna construction (Type of PCB)
thickness of conductor
distance between the windings
shielding layer
metal or ferrite in the near environment
Therefore a measurement of those parameters under real life conditions, or at least a
rough measurement and a tuning procedure is highly recommended to guarantee a
reasonable performance. For details refer to the above mentioned application notes.
