Description

The ST21NFCA 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 and peer-to-peer communication.

The ST21NFCA is designed for an optimized integration on a mobile phone with the

communication links shown in Figure 1.

This product is based on an advanced Smartcard ST21 microcontroller with 36 Kbytes of

EEPROM, 112 Kbytes of User ROM and 4 Kbytes of RAM and includes an integrated RF

Analog Front End (AFE) supporting all the contactless proximity (ISO/IEC 14443, Calypso

V1 Radio Protocol (B'), ECMA340 (NFCIP-1), and vicinity (ISO/IEC15693, ISO/IEC18000-

3Mod1) standards.

The ST21NFCA system-on-chip combines a complete hardware capability for 13.56 MHz

contactless communication with an useful embedded firmware which handles:

●

ISO/IEC 14443 A&B, Calypso V1 Radio Protocol (B'), ECMA340 (NFCIP-1), ISO/IEC

15693, ISO/IEC18000-3Mod1 in card emulation modes as well as reader modes

●

Switch modes between operating modes and RF modes

●

Host Controller Interface functions (HCI based on the ETSI specification)
