Samsung NFC Chip S3FWRN5 Offers Increased RF Performance in a Small Package
The new Samsung near field communication (NFC) chip S3FWRN5 features high radio frequency (RF) performance and small package size. The S3FWRN5’s RF performance doubles the range in both reader and card emulation modes, when compared to that of its predecessor, the S3FNRN3. As the industry’s only NFC IC built using a 45nm e-Flash process, the S3FWRN5 allows easy and secure firmware updates without having to redesign the architecture. The e-Flash portion can be safely modified through firmware updates, when new features need to be added to the chip. This enables mobile device makers to reduce the development time in comparison to solutions based on read-only memory (ROM).
The Samsung NFC chip S3FWRN5 is equipped with Samsung’s low power sensing (LPS) technology, a newly optimized algorithm to sense the signals at the lowest possible level of power consumption. The technology minimizes the NFC IC’s energy consumption, when it sends out continuous signals to recognize other NFC-enabled devices or NFC tags. By adopting LPS technology, the chip’s power requirements are reduced by approximately 25 percent when compared to Samsung’s most recent NFC product. The NFC IC is featured in the latest Samsung flagship smartphone, the Galaxy Note 4. Samsung will continue to expand the application of this NFC solution in the global market.
