Macronix builds smart lock with secure memory and ARM Cortex-M85 microcontroller
Macronix has teamed its ArmorFlash secure NOR flash memory with the Renesas RA8M1 ARM Cortex-M85 microcontrollers (MCUs) to build a smart lock.
The Macronix ArmorFlash features secure ID, authentication and encryption which can be used by the embedded security in the Renesas RA8M1 which includes the RSIP-E51A integrated security engine targeting PSA Certified Level 3 RoT Component certification. Macronix also developed an ArmorFlash driver working with the Renesas Flexible Software Package (FSP) to enhance its operational reliability.
The ArmorFlash devices use standard SPI, QSPI or OctaBus interfaces to simplify designs, and Macronix has constructed a smart lock device to demonstrate the integration of the Renesas RA8M1 MCU, ArmorFlash, FSP framework, and External Trusted Secure Storage Partition of Arm TF-M. By integrating these technologies, IoT developers can enhance data security, achieve reliable operations and simplify the development process.

“ArmorFlash is an ideal flash memory for securing data in applications, which aligns with Renesas RA8M1,” said F.L. Ni, vice president of marketing at Macronix.
“The combination of the RA8M1 and ArmorFlash’s security features will enable a broad range of data-security solutions. Furthermore, the driver that Macronix developed to interact with RA8M1 and FSP highlight ArmorFlash’s feature and its meeting RA8M1’s external-memory needs. The broad availability of RA8M1 MCUs, its dedicated FSP and ArmorFlash memory may help in increasing the number of IoT and industrial products in the market. This is particularly crucial in that market’s security-sensitive segments.”

ArmorFlash is Macronix’s family of highly secure and configurable NOR Flash devices for code and data storage. The memories also provide security solution for applications such as identification, authentication and encryption requirements for the Internet of Things (IoT), automotive, computing, industrial, healthcare systems, wearables, and smart homes and cities.
