What are the key features of TRF7961RHBTG4?
- Multi-standard support covers ISO 15693, ISO 14443A/B, and other 13.56 MHz RFID protocols in one chip
- Integrated analog front-end with programmable gain simplifies board design by eliminating discrete RF components
- 32-pin QFN package enables compact reader module designs with minimal PCB real estate
What is TRF7961RHBTG4 used for?
The TRF7961RHBTG4 is used in industrial asset-tracking readers that need to interrogate multiple RFID tag standards over a single 13.56 MHz antenna. It suits access control panels and employee badge readers where ISO 14443A smart-card compatibility is required alongside ISO 15693 inventory tags. Medical device manufacturers embed this IC in patient-ID wristband readers that demand reliable contactless data exchange within a short 10 cm read range.

Frequently Asked Questions
Which RFID protocols does the TRF7961RHBTG4 support and what frequency does it operate at?
The TRF7961RHBTG4 supports multiple high-frequency RFID standards including ISO 15693, ISO 14443A, and ISO 14443B, all operating at 13.56 MHz. This multi-standard capability allows a single reader design to communicate with a wide variety of contactless cards, tags, and wristbands without requiring separate front-end hardware for each protocol.
How does the integrated analog front-end of the TRF7961RHBTG4 reduce BOM complexity in reader designs?
The TRF7961RHBTG4 integrates programmable-gain amplifiers, demodulators, and ASK/FSK modulators on chip, eliminating the discrete RF filters and matching components typically needed around a bare RF transceiver. Designers connect an external antenna coil directly and configure gain settings over SPI, reducing the component count and shortening the RF layout verification process.
For a compact industrial RFID reader, what board space advantage does the TRF7961RHBTG4 QFN package offer?
The TRF7961RHBTG4 is housed in a 32-pin QFN (Quad Flat No-Lead) package with an exposed thermal pad, offering a small footprint suitable for hand-held and embedded reader modules where PCB space is constrained to a few square centimeters. The lead-free e4-coded package also meets RoHS requirements for use in modern industrial and consumer products.
