STMicroelectronics ST21NFCDXBGARA7 NFC Controller IC WFBGA 64 Pin Wearable Chip IC

The ST21NFCD is a single 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:
using an external Quartz.
using an external reference clock (in order to reduce the number of external
components).
Thanks to an enhanced power switch system, the ST21NFCD manages the power supply of
the device and its associated Secure Elements.
The ST21NFCD supports NCI 2.0.
In order to meet environmental requirements, ST offers these devices in dfferent grades of
ECOPACKpackages, depending on their level of environmental compliance. ECOPACK
