RFID or RF access monitoring ICs are semiconductor devices configured as RFID (Radio Frequency Identification) readers, transponders, passive entry or passive start processors and TPMS (Tire Pressure Monitorying System). They are designed to comply with specific RFID standards such as EPC, ISO, NFC, MiFARE and FeliCa, and communicate over I2C, SPI, UART, USB, PWM, RS232, RS422, RS485 and other interfaces.
