Product details
Overview
TRF7964ARHBR from Texas Instruments is a fully integrated 13.56-MHz multiprotocol RFID reader and writer IC supporting ISO/IEC 14443 A/B, ISO/IEC 15693, ISO/IEC 18000-3 Mode 1, and FeliCa™. It delivers +20 dBm (100 mW) or +23 dBm (200 mW) RF output power into 50 Ω, operates from 2.7 V to 5.5 V supply, features dual-receiver architecture with RSSI, and integrates a 127-byte FIFO for SPI or parallel MCU interface - deployed in secure access control and transit fare systems.
For engineers reviewing the TRF7964ARHBR datasheet, TRF7964ARHBR pinout, TRF7964ARHBR application, or TRF7964ARHBR equivalent, key selection considerations include its protocol flexibility across NFC/RFID standards, programmable I/O voltage levels (1.8–5.5 V), ultra-low-power modes (<1 µA in power-down), integrated 20-mA auxiliary regulator (VDD_X), and support for 848 kbps data rate in ISO/IEC 14443 A.
Technical Context
The TRF7964ARHBR implements a dual-input analog front end with independent gain control and RSSI monitoring on both RX_IN1 and RX_IN2, enabling robust ambient noise rejection and elimination of "read holes". Its digital baseband includes on-chip framing, CRC/parity generation, SOF/EOF insertion, and protocol state machines for ISO/IEC 14443 A anticollision (including broken-bytes handling).
It supports two direct modes: Direct Mode 0 provides raw subcarrier output via MOD pin; Direct Mode 1 delivers unframed but ISO-formatted data and extracted clock - allowing custom protocol implementation while bypassing internal encoders/decoders. Clocking is configurable from 13.56-MHz or 27.12-MHz crystal, with SYS_CLK outputs at RF, RF/2, or RF/4.

Equivalent & Alternatives
The following parts are listed as comparable options for similar RFID reader applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TRF7970ARHBT | Pin-to-pin and firmware compatible superset; adds NFC Forum LLCP, ISO/IEC 18092, and enhanced MIFARE compatibility | Required for NFC peer-to-peer or advanced MIFARE DESFire EV2 support; higher BOM cost | Select TRF7970ARHBT only if NFC Forum certification or extended MIFARE feature set is mandatory |
| RC663-SD001 | Infineon's 13.56-MHz reader IC; supports same protocols but uses different register map, no VDD_X regulator, and requires external 3.3-V LDO | Better suited for automotive-grade designs with AEC-Q100 qualification; lacks integrated auxiliary power | Choose RC663-SD001 when AEC-Q100 compliance or Infineon ecosystem integration outweighs need for single-supply simplicity |
Compared with TRF7964ARHBR, TRF7970ARHBT extends protocol coverage and certification readiness at higher cost and complexity, while RC663-SD001 trades integrated power regulation for automotive qualification - making TRF7964ARHBR optimal for cost-sensitive industrial and consumer readers requiring self-contained power and proven multiprotocol interoperability.

FAQ
What communication interfaces does the TRF7964ARHBR support?
The TRF7964ARHBR supports both SPI and 8-bit parallel interfaces. In SPI mode, it uses MOSI, MISO, SS, DATA_CLK, and SYS_CLK signals; in parallel mode, I/O_0 through I/O_7 serve as bidirectional data lines with IRQ for interrupt signaling. Both interfaces access the same 127-byte FIFO and share identical register mapping, enabling flexible MCU integration without firmware redesign.
Does the TRF7964ARHBR include an integrated voltage regulator for external components?
Yes, the TRF7964ARHBR includes an integrated auxiliary voltage regulator on VDD_X (pin 32), programmable from 2.7 V to 3.4 V and capable of delivering up to 20 mA. This regulator powers external MCUs or peripherals, eliminating the need for a discrete LDO in many reader designs and reducing bill-of-materials count and PCB area.
What is the maximum data rate supported by the TRF7964ARHBR across its supported protocols?
The TRF7964ARHBR supports up to 848 kbps in ISO/IEC 14443 A high-speed mode, with full hardware framing, CRC, and synchronization handled internally. For ISO/IEC 15693 and FeliCa, maximum rates are 26.48 kbps and 424 kbps respectively - all implemented without MCU intervention when using default protocol modes.
How does the dual-receiver architecture of the TRF7964ARHBR improve read reliability?
The TRF7964ARHBR's dual-receiver architecture uses RX_IN1 and RX_IN2 simultaneously to sample incoming RF signals. It computes real-time RSSI on both paths and applies adaptive gain control to suppress ambient noise or adjacent-reader interference - directly addressing "read holes" caused by destructive signal cancellation or narrowband jamming in dense RFID deployments.
Is the TRF7964ARHBR pin-compatible with any other Texas Instruments RFID ICs?
Yes, the TRF7964ARHBR is pin-to-pin and firmware compatible with the TRF7970A series (e.g., TRF7970ARHBT). This allows seamless migration to the superset device when additional features such as NFC Forum LLCP, ISO/IEC 18092, or enhanced MIFARE compatibility are required - without PCB layout changes or driver rework.
