SIP (ST21NFCD controller & ST33G1M2 Secure Element)

The ST54F is an all-in-one solution including ST21NFCD NFC controller and ST33G1M2 or ST33I1M2 Secure Element with the highest security level (EAL6+ and EMVCo certified hardware).

Fully manufactured in a secure environment, the ST33 provides the highest performance levels thanks to its ARM® SC300® core.

The 64-ball WFBGA (4 x 4 x 0.8 mm) ECOPACK® package provides a reduced footprint and pin-to-pin compatibility with the STMicroelectronics NFC standalone solution. There is no internal direct connection between the two devices inside the package.

A complete range of memory sizes up to 2048 Kbyte (depending on profile) of non-volatile Flash memory is available on the Secure Element.

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: ECOPACK® is an ST trademark.
