STMicroelectronics and YouTransactor have partnered to launch a new single-chip controller for card payment terminals.

The partnership combined YouTransactor’s market knowledge and security and POS IP, with ST’s chip-design and cyber-protection and display-graphics control IP. The resulting chip is the first PCI secure SoC for mobile payment terminals to be based on a general-purpose MCU to provide performance while reducing cost.

The YTSECPCI SoC will be commercialised by YouTransactor with ST support. Since its launch last month, YTSECPCI has been deployed in 50,000 payment terminals, and over 1 million units have been ordered for 2019-2020.

The SoC with integrated PCI (Payment Card Industry) kernel embeds all the physical security mechanisms required by PCI PTS (Pin Transaction Security) for the securing of transactions and user data. These include mesh monitoring, switch monitoring, support for secure application loading and secure boot, advanced cryptographic libraries, active software and hardware tamper detection with data-erase, card-data and pin-code protection, key management, and real-time clock (RTC) integrity protection.

Contact and contactless payment modes are supported, and the chip comes pre-certified to PCI specifications. The SoC can also be for applications including vending machines, IoT, cash registers, smartphones or retail hardware.

The chip features ST’s STM32L4 MCU with 100DMIPS/273CoreMark processing performance, large on-chip data and program memory, and ST’s Chrom-ART Accelerator. The STM32 development ecosystem can be used to develop applications, including initialization tools, free essential middleware and software, and graphical development tools available through the ST Partner program.

ST and YouTransactor have also created an evaluation board and reference design for the YTSECPCI.
