ST25R3910
Mid-range HF reader with 0.7 W supporting AAT
QFN32
Features
• Close loop adjustment of ASK modulation for accurate control of modulation depth in case of ISO-14443B protocol
• Low power (3.5 μA) NFC target mode • AM/PM demodulator • Accurate RF envelope measurement (8-bit A/D
converter) • High output power at 3.3 V power supply:
– Up to 700 mW in case regulator is externally shorted
– Up to 500 mW in case of differential output when antenna trimming is used
– Up to 125 mW in case of single ended output when antenna trimming is used
• Squelch for gain reduction, to compensate for noise generated by tag processing
• Automatic Antenna tuning (AAT) • Transparent mode • Amplitude and phase measurement • Supporting 13.56 MHz and 27.
