Engineering Brief
The TRF7964A is a fully integrated 13.56 MHz NFC/RFID reader/writer transceiver supporting ISO/IEC 14443 A/B (up to 848 kbps), ISO/IEC 15693, and FeliCa protocols with complete on-chip protocol handling. It features a dual-receiver architecture with RSSI for robust communication, programmable output power (+20 dBm / +23 dBm at 5V), a 127-byte FIFO, and supports both SPI and parallel MCU interfaces. The device operates from 2.7V to 5.5V supply with programmable I/O levels (1.8V to 5.5V), includes an integrated voltage regulator for external components (20 mA max), and offers multiple power-down modes (<1 µA) for battery-powered applications.
