Micros for IoT connectivity modules and space-constrained edge devices

Renesas Electronics has announced four new RX651 32-bit microcontrollers (MCUs) supplied in ultra-small 64-pin BGA and LQFP packages. The new lineup expands Renesas’ popular RX651 MCU Group with a 64-pin (4.5x4.5mm) BGA package that reduces footprint size by 59% compared to the 100-pin LGA, and a 64-pin (10x10mm) LQFP that offers a 49% reduction versus the 100-pin LQFP.

The MCUs address advanced security needs for endpoint devices employing compact sensor and communication modules in industrial, network control, building automation, and smart metering systems operating at the IoT edge.

“The explosive growth of the IoT and Industry 4.0 has sparked the need for higher performance, smaller form factor connectivity modules that support the various security aspects required with IoT connectivity - such as confidentiality, data integrity and availability. The RX651 delivers on this need with smaller MCU package sizes that are ideal for compact IoT applications, without compromising performance,” said Daryl Khoo, Vice President of Marketing, IoT Platform Business Division, Renesas Electronics.

“The 64-pin RX651 MCUs give customers the small footprint, high performance, and security features they need to safeguard their connected industrial and manufacturing systems against cyber attacks.”

The RX651 MCUs integrate connectivity, Trusted Secure IP (TSIP), and trusted flash area protection that enable flash firmware updates in the field through secure network communications. The increase in endpoint devices operating at the edge has increased the need for secure over-the-air (OTA) firmware updates.

The new RX651 devices support this reprogramming requirement with integrated TSIP, enhanced flash protection, and other technology advancements that offer a more secure and stable solution than other available solutions on the market.

Key features of the RX651 64-pin MCUs

  • Enables advanced IoT edge devices: The small 64-pin MCUs with enhanced security features are based on the high performance RXv2 core and 40nm process that provide superior performance with a 520 CoreMark score at 120MHz, and strong power efficiency with a 35 CoreMark/mA score as measured by EEMBC Benchmarks.
  • Easy in-the-field firmware updates: The integrated dual bank flash memory enables engineers to realise high root-of-trust levels through a combination of TSIP that protects the encryption key; encryption hardware accelerators including AES, 3DES, RSA, SHA, and TRNG; and code flash area protection to protect boot code from reprogramming. The dual bank flash function supports both BGO (Back Ground Operation) and SWAP, making it easier for manufacturers to execute in-the-field firmware updates securely and reliably.
  • Network connectivity features: Optimised for connected industrial environments, the RX651 MCUs monitor the operating state of machinery from both inside and outside the factory, enabling data exchanges to change production instructions, and reprogram MCU memory to update equipment settings.
