Product short data sheet COMPANY PUBLIC Rev. 3.2 — 20 September 2012 120132 2 of 27 NXP Semiconductors PN532/C1 Near Field Communication (NFC) controller The PN532 supports the following host interfaces: • SPI • I2C • High Speed UART (HSU) An embedded low-dropout voltage regulator allows the device to be connected directly to a battery. In addition, a power switch is included to supply power to a secure IC. 2. Features and benefits 80C51 microcontroller core with 40 KB ROM and 1 KB RAM Highly integrated demodulator and decoder Buffered output drivers to connect an antenna with minimum number of external components Integrated RF level detector Integrated data mode detector Supports ISO/IEC 14443A/MIFARE Supports ISO/IEC 14443B (Reader/Writer mode only) Typical operating distance in Reader/Writer mode for communication to ISO/IEC 14443A/MIFARE, ISO/IEC 14443B or FeliCa cards up to 50 mm depending on antenna size and tuning Typical operating distance in NFCIP-1 mode up to 50 mm depending on antenna size, tuning and power supply Typical operating distance in ISO/IEC 14443A/MIFARE or FeliCa card emulation mode of approximately 100 mm depending on antenna size, tuning and external field strength Supports MIFARE Classic 1K or MIFARE Classic 4K encryption in Reader/Writer mode and MIFARE higher transfer speed communication at 212 kbit/s and 424 kbit/s Supports contactless communication according to the FeliCa protocol at 212 kbit/s and 424 kbit/s Integrated RF interface for NFCIP-1 up to 424 kbit/s Possibility to communicate on the RF interface above 424 kbit/s using external analog components Supported host interfaces SPI interface I2C interface High-speed UART Dedicated host interrupts Low power modes Hard-Power-Down mode (1 A typical) Soft-Power-Down mode (22 A typical) Automatic wake-up on I2C, HSU and SPI interfaces when device is in Power-down mode Programmable timers Crystal oscillator 2.7 to 5.5 V power supply operating range |
