TRF7960RHBT

Updated: 2026-09-16

Overview

The TRF7960RHBT is a versatile NFC/RFID transceiver integrated circuit (IC) developed by Texas Instruments. As a key component in contactless communication systems, it enables seamless data exchange between devices using radio frequency identification (RFID) and near-field communication (NFC) technologies. The device operates in the 13.56 MHz frequency band and supports multiple international standards, making it suitable for global deployment. The IC is packaged in a compact 32-pin QFN (Quad Flat No-leads) housing, optimized for space-constrained applications. Its design focuses on both performance and power efficiency, making it equally suitable for battery-powered portable devices and fixed-installation systems. The TRF7960RHBT represents a mature solution in the contactless communication market, having been widely adopted across various industries since its introduction.

Structure and Working Principle

The TRF7960RHBT integrates both analog and digital circuitry to handle the complete RF communication chain. The analog front-end includes a transmitter with adjustable output power (up to 200 mW) and a sensitive receiver capable of demodulating weak signals. Digital processing is handled by an integrated state machine and protocol handlers that manage the complex timing requirements of RFID/NFC standards. The device operates by generating a 13.56 MHz carrier signal that powers passive RFID tags through inductive coupling. Communication follows a half-duplex scheme where the transceiver alternates between transmitting commands and listening for responses. Advanced features include automatic collision detection (for handling multiple tags) and configurable data rates from 1.65 kbit/s up to 848 kbit/s, depending on the protocol being used.

Key Features

The TRF7960RHBT stands out for its comprehensive protocol support, covering ISO/IEC 14443 A&B (used in payment cards), ISO/IEC 15693 (for item management), and NFC Forum Type 1-4 tags. This multi-protocol capability allows a single device to interact with diverse contactless cards and tags, significantly simplifying system design. Power efficiency is another notable feature, with multiple low-power modes available when the device isn't actively communicating. The integrated voltage regulator supports direct battery operation (2.7V to 5.5V range), while the configurable transmitter output power helps optimize performance versus power consumption. Diagnostic features including RSSI measurement and automatic gain control assist in system tuning and troubleshooting.

Application Areas

Payment systems represent a major application area for the TRF7960RHBT, particularly in mobile POS terminals and kiosks that accept contactless credit cards. The device's support for EMVCo (Europay, Mastercard, Visa) standards makes it suitable for secure financial transactions. In industrial settings, the IC is used for asset tracking and inventory management using ISO 15693-compatible tags. Access control systems benefit from its ability to read both proximity cards (ISO 14443) and newer NFC-enabled smartphones. Emerging IoT applications include smart packaging, where NFC tags provide product information and authentication features to consumers with compatible mobile devices.

Maintenance and Precautions

Proper antenna design and matching are critical for optimal TRF7960RHBT performance. The antenna should be tuned to 13.56 MHz with appropriate matching networks to maximize power transfer and reading range. PCB layout should minimize parasitic capacitance and keep RF traces as short as possible. ESD protection measures must be implemented, as the device's RF pins are sensitive to electrostatic discharge. During soldering, follow the recommended reflow profile to prevent thermal damage. Firmware should include checks for proper device initialization and implement timeouts to prevent lockups in noisy RF environments.

B2B Procurement Guide

When sourcing the TRF7960RHBT, verify the supply chain authenticity as counterfeit components can cause system failures. Texas Instruments authorized distributors are the most reliable sources. Consider minimum order quantities (MOQs) which typically start at 1,000 units for volume pricing. Lead times can vary from 8-12 weeks for standard orders, so plan procurement accordingly. Evaluate whether the standard industrial temperature range (-40°C to +85°C) meets your requirements or if extended options are needed. For prototype quantities, development kits that include evaluation boards and sample ICs are available to accelerate design verification.
