description

The PN736X 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.

PN736Xoffers an all in one solution, with features such as NFC, microcontroller, and

software in a single chip. It operates at CPU frequencies of up to 20 MHz. It is part of the

PN7462AU product family which offers a common set of features, library and tools.

The peripheral complement of the PN736X microcontroller 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 PN736X NFC microcontroller 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.

PN736X 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
