NXP | MFRC53101T/0FE,112

The MFRC531 is a member of a new family of highly integrated reader ICs for contactless communication at 13.56 MHz. This family of reader ICs provide: outstanding modulation and demodulation for passive contactless communication
a wide range of methods and protocols
a small, fully integrated package
pin compatibility with the MFRC500, MFRC530 and SLRC400

Features:

• Highly integrated analog circuitry for demodulating and decoding card/label response
• Buffered output drivers enable antenna connection using the minimum of external components
• Proximity operating distance up to 100 mm
• Contactless communication at MIFARE higher baud rates (up to 424 kBd)
• Crypto1 and secure non-volatile internal key memory
• Pin-compatible with the MFRC500, MFRC530 and the SLRC400
• Parallel microprocessor interface with internal address latch and IRQ line
• SPI compatibility
• Flexible interrupt handling
• Automatic detection of parallel microprocessor interface type
• 64-byte send and receive FIFO buffer
• Bit-oriented and byte oriented framing
• Independent power supply pins for analog, digital and transmitter modules
• Internal oscillator buffer optimized for low phase jitter enables 13.56 MHz quartz connection
• Clock frequency filtering
• 3.3 V to 5 V operation for transmitter in short range and proximity applications
• 3.3 V or 5 V operation for the digital module
