Product details
Overview
TRF7962ARHBR from Texas Instruments is a fully integrated 13.56-MHz RFID reader/writer IC supporting ISO/IEC 15693 and ISO/IEC 18000-3 Mode 1 protocols, with programmable output power up to +23 dBm (200 mW), dual-receiver architecture with RSSI, and parallel/SPI interface - deployed in digital door locks and medical identification systems.
For engineers reviewing the TRF7962ARHBR datasheet, TRF7962ARHBR pinout, TRF7962ARHBR application, or TRF7962ARHBR equivalent, key selection considerations include its 32-pin QFN (5 mm × 5 mm) package, 2.7–5.5 V input voltage range, 1.8–5.5 V I/O level shifter support, ultra-low-power modes (<0.5 µA in Power Down 1), and built-in voltage regulators for MCU supply (VDD_X, up to 20 mA).
Technical Context
The TRF7962ARHBR integrates analog front-end (AFE) and protocol framing logic for proximity and vicinity RFID systems. Its dual-input receiver architecture enables simultaneous signal capture from RX_IN1 and RX_IN2, with automatic and manual gain control plus RSSI reporting to mitigate read holes and ambient noise interference.
It supports data rates of 6 kbps and 26 kbps with on-chip framing/synchronization, and operates in Direct Mode 0/1 for custom protocol implementation or NFC Forum Tag Type 5 (via Direct Mode 2). The transmitter delivers selectable OOK/ASK modulation with programmable depth and output power levels of 100 mW or 200 mW into 50 Ω.
Key Specifications

Pinout & Package
TRF7962ARHBR is housed in a 32-pin VQFN package (RHB), 5 mm × 5 mm, with exposed thermal pad connected to ground. Pin functions are validated per TI SLOS757G datasheet Section 4.2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 2) | Main supply input | Accepts 2.7–5.5 V; sources internal regulators (VDD_RF, VDD_A, VDD_X) - must be highest voltage rail on board. |
| VDD_I/O (Pin 16) | I/O level shifter supply | Defines logic thresholds (1.8–5.5 V) for I/O_0–I/O_7, IRQ, SYS_CLK, DATA_CLK - decouples MCU interface voltage from core supply. |
| TX_OUT (Pin 5) | RF power amplifier output | Delivers 100/200 mW to antenna matching network; requires external 50-Ω impedance path and filtering. |
| RX_IN1 / RX_IN2 (Pins 8, 9) | Dual receive inputs | Enable spatial diversity reception; each supports 1.4–3.0 mVpp sensitivity depending on subcarrier frequency (424/848 kHz). |
| EN (Pin 28) | Chip enable | Active-high master control: EN = 0 places device in sleep/power-down; EN = 1 enables full operation or standby mode. |
| IRQ (Pin 13) | Interrupt request output | Open-drain signal indicating packet completion, error, or RSSI threshold crossing - reduces polling overhead in MCU firmware. |
| OSC_IN / OSC_OUT (Pins 31, 30) | Crystal oscillator interface | Supports 13.56 MHz fundamental-mode crystal; internal oscillator circuit eliminates need for external clock source. |
| VDD_X (Pin 32) | Digital supply regulator output | Provides regulated 2.7–3.4 V (up to 20 mA) for MCU or peripherals - simplifies system power architecture. |
Key Features
| Feature | Design Value |
|---|---|
| Fully integrated ISO/IEC 15693 & 18000-3 Mode 1 handling | Eliminates external protocol controller; all framing, CRC, parity, and synchronization executed on-die. |
| Programmable modulation depth and ASK/OOK selection | Enables optimization for tag compatibility across vendor-specific variants without hardware changes. |
| Dual-receiver with RSSI and AGC | Improves link robustness in multi-reader zones and mitigates ambient RF noise via real-time signal strength monitoring. |
| Ultra-low-power modes (PD1 & PD2) | PD1 draws <0.5 µA for true shutdown; PD2 maintains VDD_X and SYS_CLK at 60 kHz for MCU wake-up - extends battery life. |
| Built-in auxiliary voltage regulator (VDD_X) | Delivers up to 20 mA at 2.7–3.4 V - powers external MCU or sensors, reducing BOM count and PCB area. |
| Direct Mode 0/1 for custom protocols | Grants raw subcarrier/data access and AFE control - supports proprietary tag formats or NFC Forum Tag Type 1 implementation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RFID reader applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TRF7964ARHBT | Supports ISO/IEC 14443 A/B, 15693, and NFC Forum Tag Types 1–5; adds integrated NFC initiator functionality and higher RF output stability. | Better suited for dual-mode (NFC + RFID) handheld readers or point-of-sale terminals requiring card emulation. | Select TRF7964ARHBT when ISO/IEC 14443 or NFC Forum compliance is required alongside 15693 - not a drop-in replacement due to register map and timing differences. |
| SLRC610ATPH/N1 | STMicroelectronics' 13.56 MHz reader IC with integrated EEPROM, lower max output power (+18 dBm), and different SPI timing requirements. | Targeted at cost-sensitive consumer electronics and embedded modules where EEPROM-based configuration storage is preferred. | Choose SLRC610ATPH/N1 for compact, self-contained designs needing on-chip nonvolatile configuration - verify antenna matching and IRQ handling against TRF7962ARHBR layout. |
Compared with TRF7962ARHBR, TRF7964ARHBT expands protocol coverage to include ISO/IEC 14443 and NFC Forum standards but increases complexity and cost; SLRC610ATPH/N1 offers integrated EEPROM and smaller footprint but sacrifices output power and dual-receiver noise immunity.

FAQ
What communication interfaces does the TRF7962ARHBR support?
The TRF7962ARHBR supports both SPI and 8-bit parallel interfaces for host MCU communication. SPI mode uses I/O_4 (SS), I/O_5 (SCLK), I/O_6 (MISO), and I/O_7 (MOSI), while parallel mode utilizes I/O_0–I/O_7 as bidirectional data lines. TRF7962ARHBR also provides dedicated IRQ and DATA_CLK signals to simplify firmware synchronization and reduce polling overhead in real-time applications.
Does the TRF7962ARHBR include an internal voltage regulator for external MCU supply?
Yes, the TRF7962ARHBR integrates a programmable auxiliary voltage regulator on VDD_X (Pin 32), delivering up to 20 mA at 2.7–3.4 V. This output can directly power an external MCU or peripheral circuits, eliminating the need for a separate LDO in compact reader designs. TRF7962ARHBR's VDD_X regulation is controlled via register 0x0B and supports both automatic and manual configuration modes.
How does the dual-receiver architecture of the TRF7962ARHBR improve read reliability?
The TRF7962ARHBR features two independent RF inputs (RX_IN1 and RX_IN2) feeding separate analog paths with individual gain control and RSSI measurement. This architecture enables spatial diversity reception, allowing the device to select the stronger signal or combine inputs to suppress multipath fading and adjacent-reader interference. TRF7962ARHBR uses this capability to eliminate "read holes" in metal-rich or crowded RF environments - a critical advantage in access control and medical equipment ID.
What are the power consumption characteristics of the TRF7962ARHBR in low-power modes?
The TRF7962ARHBR offers two ultra-low-power states: Power Down Mode 1 draws less than 0.5 µA (all blocks disabled), and Power Down Mode 2 consumes 120–200 µA while maintaining VDD_X and SYS_CLK for MCU wake-up. TRF7962ARHBR enters these modes via EN = 0 with EN2 = 0 or 1 respectively. These modes are essential for battery-operated readers, enabling multi-year operation without compromising fast resume latency.
Can the TRF7962ARHBR be used for NFC Forum Tag Type 5 applications?
Yes, the TRF7962ARHBR natively supports NFC Forum Tag Type 5 through its built-in ISO/IEC 15693 protocol decoder in Direct Mode 2. It handles all framing, CRC, and anti-collision tasks required for Type 5 communication without external firmware intervention. TRF7962ARHBR also supports Tag Type 1 via Direct Mode 0, but requires MCU-level processing of raw subcarrier data - confirming TRF7962ARHBR's role as a flexible, standards-ready RFID front-end.
