NFC Cortex®-M0 All-in-One Microcontroller with Optional Contact Interface for Access Control
Please check the new online NFC Antenna Tool for tag and reader devices.
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.

Features
Integrated contact interface frontend
- Class A, B, and C cards can work on 1.8 V, 3 V, and 5 V supply
- Specific ISO UART, variable baud rate through frequency or division ratio programming, error management at character level for T = 0, and extra guard time register
- DC-to-DC converter for class A support starting at 3 V, and class B support starting at 2.7 V
- Thermal and short-circuit protection on contact cards
- Automatic activation and deactivation sequence, initiated by software or by hardware in case of short-circuiting, card removal, overheating, and VDD or VDD drop-out
- Enhanced ESD protection (< 12 kV)
- ISO/IEC 7816 compliant
- Compliance with EMV contact protocol specification
