The ST21NFCB is a single chip designed for supporting 13.56 MHz contactless communication, including Near Field Communication (NFC) functions in the three operating modes: Card emulation, Reader/Writer and Peer-to-peer communication. This product is based on an advanced Smartcard ST21 microcontroller with 36 Kbytes of EEPROM. It includes an integrated RF Analog Front End (AFE) supporting all the contactless proximity (ISO/IEC 14443, ECMA 340 (NFCIP-1), and vicinity (ISO/IEC 15693, ISO/IEC 18000-3 Mod1) standards. The ST21NFCB is a serial access circuit based on a 8/16-bit CPU core. Operations are synchronized with an internally generated clock issued by the Clock Generator module. Thanks to an enhanced power switch system, the ST21NFCB is able to support several power supply sources (Switched On, Switched Off and Battery Off modes) and manages the power management of the device and its associated Secure Elements.
