Renesas: 32-bit RX65N MCUs achieve Amazon FreeRTOS qualification
Renesas Electronics announced the qualification of their RX65N group of microcontrollers with Amazon FreeRTOS, running on Amazon Web Services, which makes it easy for embedded designers to create a more secure end-to-end Internet of Things cloud solution for sensor-based endpoint devices. An RX65N-based design enables sensor data transmission over Wi-Fi or Ethernet and allows users to monitor and control smart meters as well as building and industrial automation systems using a PC dashboard.
Developers can jumpstart their designs with the RX65N Renesas Starter Kit that includes a RX65N MCU with 2MB code flash memory, an LCD display module, on-chip debugging emulator, and e2 studio integrated development environment. The kit lets designers edit and debug the sample software qualified to run Amazon FreeRTOS on the RX65N MCU. Using Amazon FreeRTOS, developers can more securely deploy an RX65N MCU-based endpoint device without having to worry about the complexity of scaling across millions of devices. Once connected to the cloud, IoT endpoint device applications can take advantage of all of the cloud’s capabilities or continue processing data locally with AWS IoT Greengrass.
The RX65N MCUs feature dual bank flash, designed to improve security and facilitate easy program updating via the network. Compared to other IoT devices, industrial applications are designed for long-term operation, which involves unique and sometimes challenging requirements, such as firmware updates in the field. Having dual bank flash integrated on the RX65N MCUs enables both BGO (Back Ground Operation) and the SWAP function, making it easier for system and network control manufacturers to execute in-the-field firmware updates more securely and reliably.
The RX65N MCUs also include Trusted Secure IP as part of their built-in hardware security engine. The Trusted Secure IP driver uses strong encryption key management with hardware accelerators--AES, 3DES, SHA, RSA, and True Random Number Generator--as well as a protected boot code flash area to more securely boot customers’ IoT devices.
