PN7462 family NFC Cortex-M0 microcontroller Rev. 4.7 17 December 2021 Product data sheet 406347 COMPANY PUBLIC 1 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.

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 interfaces offer a high level of security for the card by performing current limiting, short- circuit detection, ESD protection as well as supply supervision. On PN7462AUHN, PN7412AUHN and PN7462AUEV, an additional UART output is also implemented toNXP Semiconductors PN7462 family NFC Cortex-M0 microcontroller 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. PN7462 FAM All information provided in this document is subject to legal disclaimers.
