产品概述

描述

The ST21NFCJ is a single near-field communication (NFC) controller IC designed for integration in mobile devices and NFC-compliant products. It includes NFC functions in the three operating modes: Card Emulation, Reader/Writer and Peer-to-Peer communication. This product is based on an advanced Arm Cortex-M3 32-bit microcontroller running at 28 MHz.
All internal operations are synchronized by a clock generator module.
Two clock source options are available:
Thanks to an enhanced power switch system, the ST21NFCJ manages the power supply of the device and its associated secure elements.
The ST21NFCJ supports NCI 2.0.
The ST21NFCJ comes in a 75-ball WFBGA package. It is pin-compatible with the ST54J product in wafer-level chip-scale package (WLCSP81).
In order to meet environmental requirements, ST offers these devices in different grades of ECOPACK packages, depending on their level of environmental compliance. ECOPACK specifications, grade definitions and product status are available at: www.st.com. ECOPACK is an ST trademark.
The product can come with MIFARE Classic. The availability of the MIFARE Classic R/W mode feature depends on the license conditions.
