1. Introduction
This document describes the functionality and electrical specifications of the contactless
reader/writer IC OM9663.
2. General description
The OM9663 is a highly integrated transceiver IC for contactless communication at
13.56 MHz.
The OM9663 transceiver IC supports the following operating modes
• Read/write mode supporting ISO/IEC 14443A/MIFARE
• Read/write mode supporting ISO/IEC 14443B
• Read/write mode supporting JIS X 6319-4 (comparable with FeliCa1 (see
Section 21.5) scheme)

Read/write mode supporting ISO/IEC 15693
Read/write mode supporting ICODE EPC UID/ EPC OTP
Read/write mode supporting ISO/IEC 18000-3 mode 3/ EPC Class-1 HF
The OM9663’s internal transmitter is able to drive a reader/writer antenna designed to
communicate with ISO/IEC 14443A/MIFARE 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 OM9663 supports MIFARE Classic 1K, MIFARE Classic 4K, MIFARE Ultralight,
MIFARE Ultralight C, MIFARE PLUS and MIFARE DESFire products. The OM9663
supports MIFARE higher transfer speeds of up to 848 kbit/s in both directions.
The OM9663 supports layer 2 and 3 of the ISO/IEC 14443B reader/writer communication
scheme except anticollision. The anticollision needs to be implemented in the firmware of
the host controller as well as in the upper layers.
The OM9663 is able to demodulate and decode FeliCa coded signals.The FeliCa receiver
part provides the demodulation and decoding circuitry for FeliCa coded signals. The
OM9663 handles the FeliCa framing and error detection such as CRC. The OM9663
supports FeliCa higher transfer speeds of up to 424 kbit/s in both directions.

8.1 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 OM9663 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.
The following table shows the available interrupt bits, the corresponding source and the
condition for its activation. The interrupt bit TimernIrq in register IRQ1 indicates 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 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 bit
WaterLevel.
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 bit
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.

8.2 Timer module
Timer module overview
The OM9663 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.

8.2.1 Timer modes
8.2.1.1
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.
8.2.1.2
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 OM9663 will not enter the standby mode again
in case no card is detected but stays fully powered.
8.2.1.3
Stop watch
The elapsed time between a configured start- and stop event may be measured by the
OM9663 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.
8.2.1.4
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.
8.2.1.5
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.

To enable the FeliCa communication a 6 byte preamble (00h, 00h, 00h, 00h, 00h, 00h)
and 2 bytes sync bytes (B2h, 4Dh) are sent to synchronize the receiver.
The following Len byte indicates the length of the sent data bytes plus the LEN byte itself.
The CRC calculation is done according to the FeliCa definitions with the MSB first.
To transmit data on the RF interface, the host controller has to send the Len- and databytes to the OM9663's FIFO-buffer. The preamble and the sync bytes are generated by
the OM9663 automatically and must not be written to the FIFO by the host controller. The
OM9663 performs internally the CRC calculation and adds the result to the data frame.

8.4 Host interfaces
8.4.1 Host interface configuration
The OM9663 supports direct interfacing of various hosts as the SPI, I2C, I2CL and serial
UART interface type. The OM9663 resets its interface and checks the current host
interface type automatically having performed a power-up or resuming from power down.
The OM9663 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:

Fig 12. Connection to host with SPI
The OM9663 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 OM9663 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 OM9663 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.
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 OM9663 on the falling
edge and is stable on the rising edge.The polarity of the clock is low at SPI idle.
8.4.2.2
Read data
To read out data from the OM9663 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.

Address byte
The address byte has to fulfil the following format:
The LSB bit of the first byte defines the used mode. To read data from the OM9663 the
LSB bit is set to logic 1. To write data to the OM9663 the LSB bit has to be cleared. The
bits 6 to 0 define the address byte.
NOTE: When writing the sequence [address byte][data1][data2][data3]..., [data1] is written
to address [address byte], [data2] is written to address [address byte + 1] and [data3] is
written to [address byte + 2].
Exception: This auto increment of the address byte is not performed if data is written to
the FIFO address

8.4.3 RS232 interface
8.4.3.1
Selection of the transfer speeds
The internal UART interface is compatible to a RS232 serial interface.
Table 20 “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 19 “Settings of BR_T0 and BR_T1” describes the settings of BR_T0 and BR_T1.

8.4.4 I2C-bus interface
8.4.4.1
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 OM9663 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 OM9663 I2C interface does not stretch the clock
• The OM9663 I2C interface does not support the general call. This means that the
OM9663 does not support a software reset
• The OM9663 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 OM9663.
• High speed mode is not supported by the OM9663

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 249 “I2C-bus timing in fast mode and fast mode
plus”
8.4.4.2
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.

8.4.4.3
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 OM9663 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 14) or the value of the I2C address EEPROM

I2C-register write access
To write data from the host controller via I2C to a specific register of the OM9663 the
following frame format shall be used.
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. For any other address, the
address pointer is incremented automatically and data is written to the locations [address],
[address+1], [address+2]... [address+(n-1)]
The read/write bit shall be set to logic 0.
8.4.4.8
I2C-register read access
To read out data from a specific register address of the OM9663 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 OM9663. As an answer to this device address the OM9663 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 OM9663 provides an interface option according to of a logical handling of an I2C
interface. This logical interface fulfills the I2C specification, but the rise/fall timings will not
be according the I2C standard. Standard I/O pads are used for communication and the
communication speed is limited to 5 MBaud. The protocol itself is equivalent to the fast
mode protocol of I2C. 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.

High performance NFC reader solution
The pull-up resistor is not required for the I2CL interface. Instead, a on chip buskeeper is
implemented in the OM9663 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
8.4.5 SAM interface I2C
8.4.5.1
SAM functionality
The OM9663 implements a dedicated I2C 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
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.
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. 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 cards. For multi application
purposes an architecture connecting the microcontroller additionally directly to the reader
IC is recommended. This is possible by connecting the OM9663 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.

SAM connection
The OM9663 provides an interface to connect a SAM dedicated to the OM9663. Both
interface options of the OM9663, I2C or I2CL 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.
8.4.6 Boundary scan interface
The OM9663 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:

8.4.6.1
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.
8.4.6.2
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.
8.4.6.3
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.
8.4.6.4
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.
8.4.6.5
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.
8.4.6.6
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.

8.5
Buffer
8.5.1 Overview
An 512 8-bit FIFO buffer is implemented in the OM9663. It buffers the input and output
data stream between the host and the internal state machine of the OM9663. 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.
8.5.2 Accessing the FIFO buffer
When the -Controller starts a command, the OM9663 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.
8.5.3 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.
8.5.4 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 OM9663 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:

8.6 Analog interface and contactless UART
8.6.1 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.
8.6.2 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 14
“Application information”. The signal on TX1 and TX2 can be configured by the register
DrvMode, see Section 9.8.1 “TxMode”.
The modulation index can be set by the TxAmp.

9.13.3 PLL_Ctrl Register
The PLL_Ctrl register implements the control register for the IntegerN PLL. Two stages
exist to create the ClkOut signal from the 27,12MHz input. In the first stage the 27,12Mhz
input signal is multiplied by the value defined in PLLDiv_FB and divided by two, and the
second stage divides this frequency by the value defined by PLLDIV_Out.

Framestep
If set to 1, at every start of transmission, each byte of data is sent in a
separate frame. SOF and EOF is appended to the data byte according
to the framing settings. After one byte is transmitted, the TxEncoder
waits for a new start trigger to continue with the next byte (trigger is
generated automatically). If set to 0, transmission is done in the used
way, where after a start trigger all data bytes are sent and the framing
is done for the complete data stream only once.

RxStopOnInvPar
If set to 1, inverse parity bit is a stop condition.

RxStopOnLength
If set to 1, data reception stops when the number of received
bytes reach the defined frame length. The value for the frame
length is taken from the first data-byte received.
3
RxMSBFirst
If set to 1, data bytes are interpreted MSB first for data
reception, which means data is converted at the CLCoPro
interface. If this bit is set to 0, data is interpreted LSB first.
2
RxStopBitEn
If set, a stop-bit is expected and will be checked and
extracted from data stream. Additionally on detection of a
stop-bit a reset signal for the demodulator is generator to
enable a re-synchronization of the demodulator. If the
expected stop-bit is incorrect, a frame error flag is set and the
reception is aborted.
Note: A stop bit is always considered to be a logic 1

RxEOF
Symbol
This value defines the pattern of the EOF symbol with a maximum
length of 4 bit. Every tuple of 2 bits of the RxEOFSymbol encodes one
bit of the EOF symbol. A 00 tuple closes the symbol. In this way
symbols with less than 4 bits can be defined, starting with the bit0 and
bit1. The leftmost active symbol pattern is processed first, which
means the pattern is expected first. If the bit0 and bit1 are both zero,
the EOF symbol is disabled. The following mapping is defined:
0h - no symbol bit
1h - zero value
2h - one value
3h - collision
Example:
1Dh: Zero-Collision-Zero
E8h: No symbol because two LSBits are zero

Fig 36. Typical application antenna circuit diagram
14.1 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 OM9663. 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.
14.1.1 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 OM9663 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

High performance NFC reader solution
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.
14.1.2 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.
14.1.3 Receiving circuit
The internal receiving concept of the OM9663 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 36
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).

14.1.4 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.
I1
1 8
L 1 = 2 I 1 ln ------ – K N 1
D1
(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:
•
•
•
•
•
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.
