ST combines an NFC controller, secure element and eSIM in a single mobile security chip

STMicroelectronics has launched the ST54J, a single system-on-chip that lets mobile phone makers cut bill-of-materials costs, reduce PCB space and deliver faster performance by combining an NFC controller, secure element and eSIM into one unit that supports mobile payments, e-ticketing, remote provisioning and more. “Spearheading the fourth generation of ST’s proven embedded secure element family, the single-chip ST54J ensures faster contactless interaction than a discrete chipset by eliminating performance-limiting off-chip data exchanges between the secure element and NFC controller,” ST explains.
