Infineon Technologies AG helps IoT device makers reduce firmware development risks and accelerate time-to-market with a highly integrated IoT lifecycle management solution. This industry’s first solution combines the well-known PSoC ® 64 Secure Microcontrollers with Trusted Firmware-M embedded security, the Arm ® Mbed™ IoT OS, and the Arm Pelion™ IoT platform to securely design, manage, and update IoT products without the need for custom security firmware. The Pelion-Ready and Mbed OS-Enabled solution demonstrates industry best practices for security, by reaching PSA Certified* Level 1.

“Dozens of studies have shown that a major barrier to consumer adoption of IoT products stems from concerns over privacy and security,” said Vikram Gupta, Senior Vice President of the IoT, Compute, and Wireless business unit at Infineon. “Working with our valued partner, Arm, our IoT lifecycle management solution makes it easier for device manufacturers to connect, manage, and update their products by integrating state-of-the-art security with open-source firmware.”

Implementing Trusted Firmware-M with PSoC 64 significantly simplifies device security implementation. The open-source software delivers configurable components that enable PSA Functional APIs and create a ‘Secure Processing Environment’ (SPE) for Arm Cortex ®-M-based microcontrollers. The PSoC 64 root of trust makes it easier for IoT device makers to achieve PSA Certified for their end products.

“OEMs and enterprises require flexible solutions that enable them to quickly and securely develop, deploy, and manage IoT with devices built on a secure root of trust,” said Charlene Marini, Vice President and General Manager of devices, IoT Platform, Arm. “The integration of the Arm-based PSoC 64 Secure MCU, Pelion Device Management, Mbed OS, and Trusted Firmware-M validated with PSA Certified Level 1 accreditation, provides OEMs with IoT security across the value chain from the chip to the cloud.”

The Pelion Device Management offers secured device management at every product lifecycle stage, from provisioning to decommissioning. It incorporates a dual-core architecture, with an Arm Cortex-M4 core to run applications and an Arm Cortex-M0+ core used as a security coprocessor with a pre-configured root-of-trust.

PSoC 64 is part of the IoT-AdvantEdge  solution: a comprehensive set of building blocks that enables IoT products to get to market faster and more cost effectively. IoT-AdvantEdge simplifies the design experience by delivering unfailing connectivity combined with security and local processing in an integrated solution.

Through the acquisition of Cypress Semiconductor Corporation, the PSoC 64 secure microcontroller line is now part of Infineon’s comprehensive semiconductor portfolio for automotive, industrial and IoT markets.


The PSoC 64 Secure Boot Wi-Fi/BT Pioneer Kit (CY8CKIT-064B0S2-4343W) is ready for order here. The low-cost hardware platform enables design and debug of the PSoC 64 Secure Boot MCU and the Murata Type 1DX Module (CYW4343W Wi-Fi + Bluetooth Combo Chip). Further information is available at PSoC 64 page or at .

PSA Certified provides a comprehensive framework to help fulfill its goal to improve the security of IoT devices. Independent testing of defined security standards builds trust into IoT devices and the services that rely on them.
