CR95HF - Multi protocol
CR95HF manages the frame coding and decoding in Reader mode for
standard applications such as NFC, proximity and vicinity standards.
The CR95HF embeds the Analog Front End for 13.56 MHz Air Interface.
The CR95HF supports ISO/IEC 14443 A and B, ISO/IEC 15693 (single or
double subcarrier) and ISO/IEC 18092 protocols.
Interface EEPROMs are
an innovative family of memories that provides new features and
The EEPROM memory bank
accessed either by a
standard I²C interface or by an
ISO 15693 RF interface operating at 13.56 MHz.
In this way,
you can remotely update electronic product parameters anytime during
their lifetime, anywhere in the supply chain or at the end user.
Based on two proven
industry-standard interfaces ( M24 & RFID ISO
15693 ), Dual Interface EEPROM
products also feature a unique and flexible data protection scheme that
protects some or all of the information contained in the memory.
In addition, the family features
password protection mechanism.
The ST21NFCA is a standalone chip designed for supporting 13.56 MHz contactless communication, including Near Field Communication (NFC) functions in three operating modes:
The ST21NFCA is designed for an optimized integration with the standard communication links for a cell phone.
