Using advanced design practices to increase reader efficiency while reducing the IC footprint, Texas Instruments recently announced the availability of a high-frequency (13,56 MHz), multistandard radio frequency identification (RFID) reader IC product family.
The package design of the TRF7960(1) family measures 5 x 5 mm, and supports ISO/IEC 14443A/B, ISO/IEC 15693, ISO/IEC 18000-3 and TI's contactless commerce and Tag-It portfolio.
To maximise read range and reliability, the integrated on-board linear voltage regulators that turn up the analog, digital and power amplifiers provide power supply noise isolation. The reader has an integrated analog front end and data framing system for all the supported standards. The dual receiver input configuration of the device detects amplitude modulation (AM) and phase modulation (PM), helping to eliminate read 'holes' created when antenna orientation in the operating environment changes the tag return signal from AM to PM, resulting in more consistent tag reads.
Other integrated functions include error checking, data formatting, framing and anti-collision support for multireader environments. The IC is designed for both fixed and handheld reader devices. Power consumption for the overall reader is reduced by providing seven flexible manual or automated configuration settings which shut down unused sections of the reader to save power. The TRF7960(1) operates between 2,7 and 5,5 V and when in power-down mode, consumption is less than 1 μA while standby current is less than 120 μA.

As soon as electronics and electrical systems started interfering with each other, the world had to come to some consensus. Considering physics is universal and does not care about what country electrical/electronic products are used in, it should be the same everywhere, right? It is nearly there, but not quite.
