The PN7362 is a 32-bit ARM Cortex-M0-based NFC microcontroller 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. PN7362 offers all in one solutions, with features such as NFC, microcontroller and software in a single chip. It operates at CPU frequencies of up to 20 MHz. The peripheral complement of the PN7362 microcontroller includes 160 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 PN7362 NFC microcontroller offer a one chip solution to build contactless applications. It is equipped with a highly integrated high-power output NFCIC for contactless communication at 13.56 MHz enabling EMV-compliance on RF level, without additional external active components.
