General description
The PN7462 family is a family of 32-bit ARM Cortex-M0-based NFC microcontrollers
offering high performance and low power consumption. It has a simple instruction set and
memory addressing along with a reduced code size compared to existing architectures.
PN7462 family offers an all in one solution, with features such as NFC, supporting all
NFC Forum modes, microcontroller, optional contact smart card reader, and software in a
single chip. It operates at CPU frequencies of up to 20 MHz.

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
the family also include one host interface with either high-speed mode I2C-bus, SPI, USB
or high-speed UART, and two master interfaces, SPI and Fast-mode Plus I2C-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. The PN7462AUHN contact
interface offers a high level of security for the card by performing current limiting, shortcircuit
detection, ESD protection as well as supply supervision. On PN7462AUHN 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 provides thermal and short-circuit protection on all card contacts. It
also provides automatic activation and deactivation sequences initiated by software or
hardware.
