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 leader 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 * NFC protocols - tag reader/writer, P2P * ISO/IEC 14443- type A card emulation * EMVCo compliance
