PN7462 Family | NFC Cortex-M0 low-power microcontroller for access control

Overview

The PN7462 family consists 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.
