Having the differences listed in the table above, all products within the PN7462 family
are equipped with 12 kB of SRAM data memory and 4 kB EEPROM. All products within
2
the family also include one host interface with either high-speed mode I C-bus, SPI, USB
2
or high-speed UART, and two master interfaces, SPI and Fast-mode Plus I C-bus. Four
general-purpose counter/timers, a random number generator, one CRC coprocessor and
up to 21 general-purpose I/O pins.
The PN7462 family NFC microcontroller offers a one chip solution to build contactless, or
contact and contactless applications. It is equipped with a highly integrated high-power
output NFC-IC for contactless communication at 13.56 MHz enabling EMV-compliance
on RF level, without additional external active components.
By integrating a contact ISO/IEC 7816 interface on a single chip, the PN7462AUHN
provides a solution for dual interface smart card readers. Whereas the PN7412AUHN
offers a solution for a contact reader only. The PN7462AUHN and PN7412AUHN contact
PN7462 family

interfaces offer a high level of security for the card by performing current limiting, shortcircuit detection, ESD protection as well as supply supervision. On PN7462AUHN,
PN7412AUHN and PN7462AUEV, an additional UART output is also implemented to
address applications where more than one contact card slot is needed. It enables an
easy connection to multiple smart card slot interfaces like TDA8026.
PN7462AUHN and PN7412AUHN provide thermal and short-circuit protection on all card
contacts. It also provides automatic activation and deactivation sequences initiated by
software or hardware.

Functional description
8.1 Arm Cortex-M0 microcontroller
The PN7462 family is an Arm Cortex-M0-based 32-bit microcontroller, optimized for lowcost designs, high energy efficiency, and simple instruction set.
The CPU operates on an internal clock, which can be configured to provide frequencies
such as 20 MHz, 10 MHz, and 5 MHz.
The peripheral complement of the PN7462 family includes a 160 kB flash memory, a 12
kB SRAM, and a 4 kB EEPROM. It also includes one configurable host interface (Fast2
mode Plus and high-speed I C, SPI, HSUART, and USB), two master interfaces (Fast2
mode Plus I C, SPI), 4 timers, 12 general-purpose I/O pins, one ISO/IEC 7816 contact
card interface (PN7462AUHN only), one ISO/IEC 7816-3&4 UART (PN7462AUHN and
PN7462AUEV only) and one 13.56 MHz NFC interface.
8.2 Memories
8.2.1 On-chip flash programming memory
The PN7462 family contains160 / 80 kB on-chip flash program memory depending on
the version. The flash can be programmed using In-System Programming (ISP) or InApplication Programming (IAP) via the on-chip boot loader software.
The flash memory is divided into two instances of 80 kB each, with each sector
consisting of individual pages of 64 bytes.
8.2.1.1 Memory mapping
The flash memory mapping is described in Figure 9.

8.2.4 ROM
The PN7462 family contains 40 kB of on-chip ROM memory. The on-chip ROM contains
boot loader, USB mass storage primary download, and the following Application
Programming Interfaces (APIs):
• In-Application Programming (IAP) support for flash
• Lifecycle management of debug interface, code write protection of flash memory and
USB mass storage primary download
• USB descriptor configuration
• Configuration of timeout and source of pad supply
8.2.5 Memory map
The PN7462 family incorporates several distinct memory regions. Figure 12 shows the
memory map, from the user program perspective, following reset.
The APB peripheral area is 512 kB in size, and is divided to allow up to 32 peripherals.
Only peripherals from 0 to 15 are accessible. Each peripheral allocates 16 kB, which
simplifies the address decoding for the peripherals. APB memory map is described in
Figure 13 and Figure 14.

• Remark: To support class A cards, DC-to-DC converter is used in doubler mode. To
support class B cards with VDDP(VBUSP) < 3.9 V, DC-to-DC converter is used in doubler
mode. To support class B cards with VDDP(VBUSP) > 3.9 V, DC-to-DC converter is used
in follower mode.
Figure 16 shows the classes that are supported, depending on VDDP(VBUSP).

Figure 16. VDDP(VBUS), supported contact cards classes, and card deactivation
When the VDDP(VBUSP) is going below the threshold value, in the one of the conditions
indicated below, a card deactivation is performed:
• Class A card activated, and VDDP(VBUSP) going below 3 V
• Class B card activated, and VDDP(VBUSP) going below 3.9 V (DC-to-DC converter in
follower mode)
• Class B card activated, and VDDP(VBUSP) going below 2.7 V (DC-to-DC converter in
doubler mode)
• Class C card activated, and VDDP(VBUSP) going below 2.7 V
The VBUSP voltage monitor can be configured so that an automatic "card deactivation"
sequence is performed automatically when VDDP(VBUSP) is going below the threshold
value.
8.9.3 Clock circuitry
The card clock is generated from the crystal oscillator, connected on the pin XTAL1 and
XTAL2.
The card frequency is configured through the contact interface registers. The following
value can be chosen: fXTAL / 2, fXTAL / 3, fXTAL / 4, fXTAL / 5, fXTAL / 6, fXTAL / 8, and fXTAL /
16.
It is possible to put the card clock to a logical level 0 or 1 (clock stop feature).
The duty cycle on the pin CLK is between 45 % and 55 %, for all the available clock
dividers.
8.9.4 I/O circuitry
The three data lines I/O, AUX1, and AUX2 are identical.
I/O is referenced to VCC. To enter in the idle state, the I/O line is pulled HIGH via a 10 kΩ
resistor (I/O to VCC).

The active pull-up feature ensures fast LOW to HIGH transitions. At the end of the active
pull-up pulse, the output voltage depends on the internal pull-up resistor and the load
current.
The maximum frequency on these lines is 1.5 MHz.
8.9.5 VCC regulator
VCC regulator delivers up to 60 mA for class A cards (0 V to 5 V). It also delivers up to
55 mA for class B cards (0 V to 3 V) and up to 35 mA for class C cards (from 0 V to 1.8
V).
The VCC has an internal overload detection at approximately 110 mA for class A and B,
and 90 mA for class C.
This detection is internally filtered, allowing the card to draw spurious current pulses as
defined in EMVCo specification, without causing a deactivation. The average current
value must remain below the maximum.
8.9.6 Activation sequence
The presence of a contact card is indicated to PN7462 through PRESN signal. If all
supply conditions are met, the PN7462 may start an activation sequence. Figure 17
shows the activation sequence.
The sequencer clock is based on the crystal oscillator: fseq = fXTAL /10. When the contact
interface is active, the period for activation phases is: T = 64/fseq = 23.6 μs.

PN7462 family supports the following features:
• TARI = 9.44 μs or 18.88 μs
• Downlink: Four subcarrier pulse Manchester and two subcarrier pulse Manchester
• Subcarrier: 423 kHz (fc / 32) with DR = 0 kHz and 847 kHz (fc / 16) with DR = 1
8.10.1.6 NFCIP-1 modes
The NFCIP-1 communication differentiates between an active and a passive
communication mode.
• In active communication mode, both initiator and target use their own RF field to
transmit data
• In passive communication mode, the target answers to an initiator command in a load
modulation scheme. The initiator is active in terms of generating the RF field
• The initiator generates RF field at 13.56 MHz and starts the NFCIP-1 communication
• In passive communication mode, the target responds to initiator command in load
modulation scheme. In active communication mode, it uses a self-generated and selfmodulated RF field.

NFCIP-1 protocol support
The NFCIP-1 protocol is not elaborated in this document. The PN7462 family component
does not implement any of the high-level protocol functions. These high-level protocol
functions are implemented in the microcontroller. For detailed explanation of the protocol,
refer to the NFCIP-1 standard. However, the datalink layer is according to the following
policy:
• Speed shall not be changed while there is continuous data exchange in a transaction.
• Transaction includes initialization, anticollision methods, and data exchange (in a
continuous way means no interruption by another transaction).
In order not to disturb current infrastructure based on 13.56 MHz, the following general
rules to start NFCIP-1 communication are defined:
1.
2.
3.
4.
By default, NFCIP-1 device is in target mode. It means that its RF field is switched off.
The RF level detector is active.
Only if the application requires, the NFCIP-1 device switches to initiator mode.
An initiator shall only switch on its RF field if the RF level detector does not detect
external RF field during a time of TIDT.
5. The initiator performs initialization according to the selected mode.
8.10.2 NFC interface
8.10.2.1 Transmitter (TX)
The transmitter is able to drive an antenna circuit connected to outputs TX1 and TX2
with a 13.56 MHz carrier signal. The signal delivered on pins TX1 and pin TX2 is a 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. For a differential antenna configuration, either TX1 or TX2 can be configured to
put out an inverted clock.
100 % modulation and several levels of amplitude modulation on the carrier can be
performed to support 13.56 MHz carrier-based RF-reader/writer protocols. The standards
ISO/IEC14443 A and B, FeliCa, and ISO/IEC18092 define the protocols.
The PN7462 family embeds an overshoot and undershoot protection. It is used to
configure additional signals on the transmitter output, for controlling the signal shape at
the antenna output.

8.10.2.2 Receiver (RX)
In reader mode, the response of the PICC device is coupled from the PCB antenna to
the differential input RXP/RXN. The reader mode receiver extracts this signal by first
removing the carrier in passive mixers (direct conversion for I and Q). It then filters
and amplifies the baseband signal before converting to digital values. The conversion
to digital values is done with two separate ADCs, for I and Q channels. Both I and Q
channels have a differential structure, which improves the signal quality.
The I/Q mixer mixes the differential input RF-signal down to the baseband. The mixer has
a bandwidth of 2 MHz.
The down-mixed differential RX input signals are passed to the BBA and a band-pass
filter. For considering all the protocols (type A/B, FeliCa), the high-pass cut-off frequency
of BBA is configured between 45 kHz and 250 kHz. The configuration is done in four
different steps. The low-pass cut-off frequency is greater than 2 MHz.
The output of band-pass filter is further amplified with a gain factor which is configurable
between 30 dB and 60 dB. The baseband amplifier (BBA)/ADC I-channel and Q-channel
can be enabled separately. It is required for ADC-based card mode functionality as only
the I-channel is used in this case.

VMID
A resistive divider between AVDD and GND generates VMID. The resistive divider is
connected to the VMID pin. An external blocking capacitor of typical value 100 nF is
connected.
Automatic Gain Control (AGC)
The NFC interface AGC is used to control the amplitude of 13.56 MHz sine-wave input
signal received. The signal is received at the antenna connected between the pins RXP
and RXN. A comparator is used to compare the peak value of the input signal with a
reference voltage.
A voltage divider circuit is used to generate the reference voltage. An external resistor
(typically 3.3 kΩ) is connected to the RX input, which forms a voltage divider with an onchip variable resistor. The voltage divider circuit so formed has a 10-bit resolution.
Note: The comparator monitors the RXP signal only.
By varying the on-chip resistor, the amplitude of the input signal can be modified. The
value of on-chip resistor is increased or decreased, depending on the output of the
sampled comparator. The on-chip resistor value is adjusted until the peak of the input

signal matches the reference voltage. Thus, the AGC circuit automatically controls the
amplitude of the RX input.
The internal amplitude controlling resistor in the AGC has a default value of 10 KΩ. It
means that, when the resistor control bits in AGC_VALUE_REG are all 0, the
resistance is 10 KΩ. As the control bits are increased, resistors are switched in parallel to
the 10 KΩ resistor. It lowers the resultant resistance value to 5 kΩ (AGC_VALUE_REG
, all bits set to 1).
Mode detector
The mode detector is a functional block of the PN7462 family which senses for an RF
field generated by another device. The mode detector facilitates to distinguish between
type A and FeliCa target mode. The host responds depending on the recognized
protocol generated by an initiator peer device.
Note: The PN7462 family emulates type A cards and peer-to-peer active target modes
according to ISO / IEC18092.
8.10.3 Low-Power Card Detection (LPCD)
The low-power card detection is an energy saving feature of the PN7462 family. It
detects the presence of a card without starting a communication. Communication
requires more energy to power the card and takes time, increasing the energy
consumption.
It is based on antenna detuning detection. When a card comes close to the reader, it
affects the antenna tuning, which is detected by PN7462 family.
The sensitivity can be varied for adjusting to various environment and applications
constraints.
Remark: Reader antenna detuning may have multiple sources such as cards and metal
near the antenna. Hence it is important to adjust the sensitivity with care to optimize the
detection and power consumption. As the generated field is limited, distance for card
detection might be reduced compared to normal reader operation. Performances depend
on the antenna and the sensitivity used.
8.10.4 Active Load Modulation (ALM)
When PN7462 family is used in card emulation mode or P2P passive target mode, it
modulates the field emitted by the external reader or NFC passive initiator.

characteristics, which are detected by the reader through antenna coupling.

• Active Load Modulation (ALM): The PN7462 family generates a small field, in phase
opposition with the field emitted by the reader. This modulation is detected by the
reader reception stage.
The modulation type to use depends on the external reader and the antenna of PN7462
family and the application.
8.10.5 Dynamic Power Control (DPC)
The PN7462 family supports the Dynamic Power Control (DPC) feature.
A lookup table is used to configure the output voltage and to control the transmitter
current. In addition to the control of the transmitter current, wave shaping settings can be
controlled as well, depending on the selected protocol and the measured antenna load.
8.10.5.1 RF output control
The DPC controls the RF output current and output voltage depending on the loading
condition of the antenna.
8.10.5.2 Adaptive Waveform Control (AWC)
The DPC includes the Adaptive Waveform Control (AWC) feature.
Depending on the level of detected detuning on the antenna, RF wave shaping related
register settings can be automatically updated, according to the selected protocol. A
lookup table is used to configure the modulation index, the rise time and the fall time.
8.11 Timers
The PN7462 family includes two 12-bit general-purpose timers (on LFO clock domain)
with match capabilities. It also includes two 32-bit general-purpose timers (on HFO clock
domain) and a Watchdog Timer (WDT).
The timers and WDT can be configured through software via a 32-bit APB slave
interface.

Figure 33. PN7462 LDOs and power pins overview
PN7462 embeds five Low Drop-Out regulators (LDO) for ensuring the stability of power
supply, while the application is running.
• MLDO (main LDO): It provides 1.8 V supply for internal analog, digital and memory
modules
• TXLDO: This LDO can be used to supply the RF transmitter
• PVDD_LDO: PVDD_LDO provides 3.3 V that can be used for all pads supply
• SCLDO: This LDO provides a 2.4 V output to be used for contact card supply. The
main aim is to be able to address class B operation when the voltage available is
below 3.9 V. It is achieved by providing a stable input voltage to the internal DC-to-DC
converter.
• VCC_LDO: the VCC_LDO provides the supply for the contact smart card
Some are used while some are optional, like the TX_LDO which is proposed for the RF
interface. It is up to the application designer to decide whether LDOs should be used.
8.15.2.1 Main LDO

8.15.2.2 PVDD_LDO
The PVDD_LDO provides 3.3 V supply, that can be used for all digital pads. It may also
be used to provide 3.3 V power to external components, avoiding an external LDO. It is
supplied by VBUS, and requires a minimum voltage of 4 V to be functional. It delivers a
maximum of 30 mA.
The output pin for PVDD_LDO is PVDD_OUT.
PVDD_LDO is used to provide the necessary supply to PVDD_IN and PVDD_M_IN (pad
supply for master interfaces).
When an external supply is used, PVDD_OUT must be connected to the ground. When
the LDO output is connected to the ground, the chip switches off the PVDD_LDO.
The PVDD_LDO has a low-power mode, which is used automatically when the chip is in
standby mode or suspend mode. It facilitates supply to HOST pads and GPIOS, and to
detect wake-up signals coming from these interfaces.
Following are the PVDD_LDO features:
• Low-Drop-Out voltage regulator powered by VDDP(VBUS) (external supply)
• Supports soft-start mode to limit inrush current during the initial charge of the external
capacitance when the LDO is powered up
• Current limiter to avoid damaging the output transistors
Note: When PVDD_LDO is used, there must not be any load current drawn from
PVDD_LDO during the soft start of the PVDD_LDO.
8.15.2.3 Contact interface - SCLDO LDO
The SCLDO provides a regulated voltage to the DC-to-DC converter, to enable class B
operation when VDDP(VBUS) is in between 2.7 V to 3.9 V.
Following are the contact interface features:
• Current limiter for short circuit protection
• Supports soft-start mode to limit the inrush current during the initial charge of the
external capacitance when the LDO is powered up
8.15.2.4 Contact interface DC-to-DC converter
The PN7462 includes a DC-to-DC converter that supports class A and class B cards,
when the input voltage VDDP(VBUSP) is not sufficient.
The DC-to-DC converter is a capacitance voltage doubler. It takes power from the
SCLDO. The DC-to-DC converter can be bypassed. Its output (VUP) is regulated
between 3.3 V to 5.5 V.
The DC-to-DC converter can work in the following modes:
• Follower mode: This mode is used when VDDP(VBUSP) is high enough to provide the
desired power to the VCC LDO
• Doubler mode: This mode is used when VDDP(VBUSP) is not high enough to supply the
requested VCC output
The doubler mode is used in the following conditions:
• Class A cards support
• Class B cards support, when VDDP(VBUSP) is less than 3.9 V

8.15.2.6 TXLDO
The PN7462 family consists of an internal transmitter supply LDO. The TXLDO can be
used to maintain a constant output voltage for the NFC interface.
The TXLDO is designed to protect the chip from voltage ripple introduced by the power
supply on the pin VUP_TX. It is powered through the pin VUP_TX.
The programmable output voltages are: 3.0 V, 3.3 V, 3.6 V, 4.5 V, and 4.75 V.
For a given output voltage, VUP_TX shall always be higher than 0.3 V. In other words,
to supply a 3 V output, the minimum voltage to be applied on VUP_TX is 3.3 V. If the
voltage is not sufficient, then the voltage at the pin TVDD_OUT follows the voltage at the
pin VUP_TX, lowered of 0.3 V.
When it is not used, TVDD_OUT shall be connected to TVDD_IN and VUP_TX, and
TX_LDO shall be turned off. It must be ensured, that TVDD_IN and TVDD_OUT are
never higher than VUP_TX.
Following are the TXLDO features:
• Low-Drop-Out (TXLDO) voltage regulator
• Supports soft-start mode to limit inrush current during the initial charge of the external
capacitance
• Current limiter to avoid damaging the output transistors

PN7462 family
NXP Semiconductors
NFC Cortex-M0 microcontroller
The output pin for PVDD_LDO is PVDD_OUT.
PVDD_LDO is used to provide the necessary supply to PVDD_IN and PVDD_M_IN (pad
supply for master interfaces).
When an external supply is used, PVDD_OUT must be connected to the ground. When
the LDO output is connected to the ground, the chip switches off the PVDD_LDO.
The PVDD_LDO has a low-power mode, which is used automatically when the chip is in
standby mode or suspend mode. It facilitates supply to HOST pads and GPIOS, and to
detect wake-up signals coming from these interfaces.
Following are the PVDD_LDO features:
• Low-Drop-Out voltage regulator powered by VDDP(VBUS) (external supply)
• Supports soft-start mode to limit inrush current during the initial charge of the external
capacitance when the LDO is powered up
• Current limiter to avoid damaging the output transistors
Note: When PVDD_LDO is used, there must not be any load current drawn from
PVDD_LDO during the soft start of the PVDD_LDO.
8.15.3.3 TXLDO
The PN7462 family consists of an internal transmitter supply LDO. The TXLDO can be
used to maintain a constant output voltage for the NFC interface.
The TXLDO is designed to protect the chip from voltage ripple introduced by the power
supply on the pin VUP_TX. It is powered through the pin VUP_TX.
The programmable output voltages are: 3.0 V, 3.3 V, 3.6 V, 4.5 V, and 4.75 V.
For a given output voltage, VUP_TX shall always be higher than 0.3 V. In other words,
to supply a 3 V output, the minimum voltage to be applied on VUP_TX is 3.3 V. If the
voltage is not sufficient, then the voltage at the pin TVDD_OUT follows the voltage at the
pin VUP_TX, lowered of 0.3 V.
When it is not used, TVDD_OUT shall be connected to TVDD_IN and VUP_TX, and
TX_LDO shall be turned off. It must be ensured, that TVDD_IN and TVDD_OUT are
never higher than VUP_TX.
Following are the TXLDO features:
• Low-Drop-Out (TXLDO) voltage regulator
• Supports soft-start mode to limit inrush current during the initial charge of the external
capacitance
• Current limiter to avoid damaging the output transistors

USB suspend mode
Active mode
8.15.5.1 Active mode
In active mode, all functionalities are available and all IPs can be accessed. It is possible
to configure the various clocks (IP clock, system clock) using register settings so that
chip consumption is reduced. If IPs are not used, they can be disabled.
8.15.5.2 Standby mode
In standby mode, only a reduced part of the digital and the analog is active. It reduces
the chip power consumption. The possible wake-up sources are still powered.
The LFO clock is used to lower the energy needs.
Active part in standby mode: Main LDO is active, in a low-power mode, plus all
configured wake-up sources.
Depending on the application requirements, it is possible to configure PVDD_LDO in
active mode, low-power mode or shut down mode when PN7462 family is going to
standby mode. PVDD_LDO is active in a low-power mode by default.
Entering in standby mode: The application code triggers standby mode. Before
entering in standby mode, the PN7462 manages the deactivation of the contact card.
The PN7462 family has two internal temperature sensors. If these sensors detect an
overheat, the chip is put into standby mode by the application firmware. It leaves the
standby mode when both temperature sensors indicate that the temperature has come
below the configured limit.
Limitations: Standby mode is not possible in the following cases:
• A host communication is in progress.
• A wake-up condition is fulfilled. For example, external NFC field presence is a wake-up
source, and a field is detected.
• The NFC field detector is a possible wake-up source, and the NFC field detector is
disabled.
• PVDD is not present.
8.15.5.3 Suspend mode
In suspend mode, clock sources are stopped except LFO. It reduces the chip power
consumption.
Entering in suspend mode: An interrupt indicates to the application firmware when no
activity has been detected on the USB port for more that 3 ms. The application code
triggers the suspend mode.
Before entering in suspend mode, the PN7462 manages automatically, the deactivation
of the contact card.
Limitations: Suspend mode is prevented in the following cases:
• A host communication is in progress.
• A wake-up condition is fulfilled. For example, external RF field presence is a wake-up
source, and a field is detected.

• The RF field detector is a possible wake-up source, and the RF field detector is
disabled.
• No voltage at pin PVDD.
8.15.5.4 Wake-up from standby mode and suspend mode
PN7462 family can be woken-up from standby mode, and suspend mode, using the
following means:
2
• Host Interface: SPI, HSUART, I C, and USB if already selected before standby mode
2
(SPI, HSUART, and I C) or suspend mode (USB).
• RF field detection (presence of a reader or an NFC device in reader mode or P2P
initiator)
• GPIO
• Contact card insertion, contact card removal (PN7462AUHN only)
• Interrupt generated on the auxiliary UART interface, through the interrupt pin
(PN7462AUHN and PN7462AUEV only)
• Wake-up counter, for example to timely check for the presence of any contact or
contactless card
• Current overconsumption on the PVDD_OUT, voltage above 5 V on TVDD_IN
• Temperature sensor: When the chip goes in to standby mode because of over-heating,
and when the temperature goes below the sensor configured value, it wakes-up
automatically. Each temperature sensor can be configured separately.
It is possible to configure the sources as enabled or disabled.
8.15.5.5 Hard Power-Down (HPD) mode
The Hard Power-Down (HPD) reduces the chip power consumption, by powering down
most of its blocks. All clocks and LDOs are turned off, except the main LDO which is set
in low-power mode.
Entering in HPD mode: If the RST_N pin is set to low, the NFC controller enters in to
Hard Power Down (HPD) mode. It also enters in to HPD mode if the VDDP(VBUS) goes
below the critical voltage necessary for the chip to work (2.3 V) and the auto HPD feature
is enabled.
Exiting the HPD mode: The NFC controller leaves the HPD mode, when both RST_N
pin is set to high level and the VDDP(VBUS) voltage is above 2.3 V.
8.15.6 Voltage monitoring
The voltage monitoring mode detects whether the voltage is within the operational
conditions to enable a proper operation of the RF interface or the contact interface. The
following power supplies are monitored: VBUS (two voltage monitors), VBUS_P (one
voltage monitor).
Section 9.1.2 discusses about the minimum voltages necessary for NFC interface
operation and Section 9.1.3 for the contact interface operation.

8.15.6.1 VBUS monitor
The PN7462 family includes up to two levels (2.3 V or 2.7 V) for monitoring the voltage
on the VBUS pin. If this voltage falls below one of the selected levels, the BOD asserts
an interrupt signal to the PCR. This signal may be enabled for interrupt in the interrupt
enable register in the PCR, to cause a CPU interrupt. Alternatively, software can monitor
the signal by reading a dedicated status register. Two threshold levels (2.3 V or 2.7 V)
can be selected to cause a forced Hard Power-Down (HPD) of chip.
8.15.6.2 VBUSP monitor
The PN7462 family includes three levels (2.7 V, 3.0 V, and 3.9 V) for monitoring the
voltage on the VBUSP pin.
In addition to the above, the following applies to products with contact interface: When
the voltage falls below the selected threshold value, and CT automatic deactivation
is enabled in the PCR system register, hardware automatically de-activates the CT
interface. An interrupt signal is also asserted to the PCR. This signal can be enabled for
interrupt in the interrupt enable register in the PCR, to cause a CPU interrupt. Software
must check VBUSP monitor levels by reading dedicated status registers before starting
card activation sequence.
8.15.6.3 PVDD LDO supply monitor
The PN7462 family includes up to two levels (VBUSMON2: 2.7 V or 4.0 V) for monitoring
the voltage on the PVDD LDO input supply. If supply voltage is 4.0 V or above, PVDD
LDO can be enabled. The software has to check whether the voltage is sufficient before
enabling the LDO.
8.15.7 Temperature sensor
The PN7462 family power management unit provides temperature sensors, associated
to the TX_LDO. It detects problems that would result in high power consumption and
heating, which could damage the chip and the user device.
Triggering levels are configurable. Following temperatures can be chosen: 135 °C,
130 °C, 125 °C, and 120 °C. By default, the temperature sensor is set to 120 °C.
Once the configured threshold is reached, an interrupt is generated. The application
decides whether to enter standby or suspend mode. The triggering temperature sensor is
indicated in the interrupt register.
Once the temperature goes below the configured threshold temperature, the NFC
controller wakes up automatically.

The watchdog reset, I C reset and soft resets from PCR and Arm processor resets the
chip except the PCR and the Arm debug interface. The Power-On Reset (POR) resets
the complete chip including the PCR and Arm debug interface.
Upon reset, the processor executes the first instruction at address 0, which is initially the
reset vector mapped from the boot block. At that point, all the processor and peripheral
registers are initialized to predetermined values.
8.16.2 Brown-Out Detection (BOD)
The PN7462 family includes up to two levels for monitoring the voltage on the VBUS pin.
If this voltage falls below one of the selected voltages (2.3 V or 2.7 V), the BOD asserts
an interrupt signal to the PCR. This signal can be enabled for interrupt in the interrupt
enable register in the PCR, to cause a CPU interrupt. Alternatively, software can monitor
the signal by reading a dedicated status register. Two threshold levels (2.3 V and 2.7 V)
can be selected to cause a forced Hard Power-Down (HPD) of the chip.
8.16.3 APB interface and AHB-Lite
All APB peripherals are connected to one APB bus.
The AHB-Lite connects the AHB masters. The AHB masters include the CPU bus of the
Arm Cortex-M0, host interface, NFC interface, SPI interface to the flash memory. It also
includes EEPROM memory, SRAM, ROM, and AHB to APB bridge.
8.16.4 External interrupts
PN7462 family enables the use of 12 GPIOs as edge or level sensitive inputs (GPIO1 to
GPIO12).
8.17 SWD debug interface
TM
The Cortex-M0 processor-based devices use serial wire Arm CoreSight Debug
technology. The PN7462 family is configured to support four break points and two watch
points.
The SWD interface can be disabled for having code (or data) read/write access
protection. A dedicated SWD disable bit is available in the protected area of the

Remark: The capacitance must be chosen so that the capacitance value is correct at 5 V
Figure 37. Powering up the microcontroller
The schematics in Figure 37 describe the power supply of the chip (VDDP(VBUS)),
including the digital blocks supply (DVDD). It indicates two possibilities to supply the
pads, using the internal LDO, or using an external supply. The internal LDO requires that
VDDP(VBUS) > 4 V. It avoids the requirement of a separate LDO when VDDP(VBUS) has a
sufficient voltage.
Power supply is available to pads through PVDD_IN (host interface). Similarly, power
supply is available to master interface pads through PVDD_M_IN. When PVVD _LDO is
used, maximum total current available from PVDD_OUT for the pads supply is 30 mA.
When an external source is used for PVDD_IN and PVDD_M_IN, PVDD_OUT must be
connected to the ground, with a ground resistance of less than 10 Ω.
9.1.2 Powering up the contactless interface
Powering of contactless interface is done though TVDD_IN. Internal LDO (TXLDO) or
