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 all in one solutions, with features such as NFC, microcontroller, optional contact smart card reader, and software in a single chip. It operates at CPU frequencies of up to 20 MHz. The family includes the following derivatives to fit every specific need: • PN7462: NFC microcontroller, 160 kB Flash memory, and an ISO 7816/EMVCo contact interface The peripheral complement of the PN7462 family microcontrollers includes 160/80 kB of flash memory, 12 kB of SRAM data memory and 4 kB EEPROM. It also includes 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 are also available. The PN7462 family NFC microcontrollers offer a one chip solution to build 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 PN7462 family supports the following operating modes: • ISO/IEC 14443-A and B, MIFARE • JIS X 6319-4 (comparable with FeliCa scheme) • ISO/IEC 15693, ICODE, ISO/IEC 18000-3 mode 3 • NFC protocols - tag reader/writer, P2P • ISO/IEC 14443- type A card emulation • EMVCo compliance By integrating an ISO/IEC 7816 interface on a single chip in the PN7462, it provides a solution for dual interface smart card readers. PN7462 contact interface offers a high level of security for the card by performing current limiting, short-circuit detection, ESD protection as well as supply supervision. 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.
