SIP (ST21NFCC controller & ST33G1M2 Secure element)

The ST54E is an all-in-one solution including NFC controller and Secure Element with the highest security level (EAL5+ and EMVCo certified hardware).

Connected to a NFC active RF Front-End, the NFC controller offers a complete solution for 13.56 MHz contactless communication.

Fully manufactured in a secure environment, it provides the highest performance levels thanks to its ARM® SC300® core and advanced 90-nm e-Flash technology.

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 from 128 to more than 600 Kbytes (depending on profile) 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.
