Rc522 Proteus Library Updated -
Wiring (SPI Connections):
| RC522 Pin | Arduino Uno Pin | Proteus Net Label |
| :--- | :--- | :--- |
| SDA (SS) | Digital 10 | SS |
| SCK | Digital 13 | SCK |
| MOSI | Digital 11 | MOSI |
| MISO | Digital 12 | MISO |
| IRQ | Not connected | |
| GND | GND | GND |
| RST | Digital 9 | RST |
| 3.3V | +3.3V (Uno's 3.3V out) | +3.3V |
Critical Update Tip: The new library correctly simulates the 3.3V logic level. Do not connect to +5V.

For electronics hobbyists, embedded system developers, and engineering students, Proteus Virtual System Modeling (VSM) is a game-changer. It allows you to simulate microcontroller circuits without physical hardware. Among the most sought-after components for simulation is the RC522 RFID Module—a popular, low-cost device used for contactless communication (13.56 MHz) with tags and cards.
However, for years, simulating the RC522 in Proteus was a nightmare. Older libraries were buggy, lacked proper SPI protocol handling, or simply crashed the software. This led to a common frustration: “My code works on hardware, but not in simulation.” LCD Wiring: (Standard 4-bit mode – D4 to
The good news? The RC522 Proteus Library has been updated. This comprehensive guide covers everything you need to know about the latest version, how to install it, its new features, and how to simulate a complete RFID project step-by-step.
