ST53G (ST31G + STS3922) Secure SIP product for optimized wearable (Card emulation)

The ST53G device is an all-in-one secure solution that includes the STS3922 near-field communication (NFC) booster and a secure element (SE) certified by EMVCo and available in different memory sizes ranging from 256 to 480 Kbytes (ST31G480, ST31G384, ST31G320 or ST31G256).

Fully manufactured in a secure environment, the ST53G provides the highest performance levels thanks to the ARM® SC300® core of their secure element.

The ST53G is ideal for applications that require card emulation functionality, but have limited space for the antenna. This solution allows a simpler design than the conventional NFC controller-based architecture, and occupies a board footprint approximately one-third smaller.

The ST53G operates in the −25 to + 85 °C temperature range at voltages from 2.7 to 3.6 V.

It is delivered in WFBGA64 packages dimensioned for use in small-footprint devices.

In order to meet environmental requirements, ST offers the ST53G 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.
