STMicroelectronics ST25TA NFC Technology

摘要

Near Field Communication (NFC) is a standard short-range wireless technology, typically with a range of 10 cm or less. It operates at 13.56 MHz using the ISO/IEC 14443 RF interface at a data rate of 106 Kbit/s. Here we look at an enhanced NFC tag, the ST25TA now being rolled out by STMicroelectronics. Compared to earlier products, the ST25TA has many extra features which should arouse every e-engineer's interest.
