32-bit MCUs for IoT edge devices

25 September 2019 DSP, Micros & Memory

Renesas Electronics announced four new RX651 32-bit microcontrollers (MCUs) supplied in ultra-small 64-pin BGA and LQFP packages.

The new lineup expands the RX651 MCU group with a 64-pin (4,5 x 4,5 mm) BGA package that reduces footprint size by 59% compared to the 100-pin LGA, and a 64-pin (10 x 10 mm) 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 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 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.

The small 64-pin MCUs are based on the high-performance RXv2 core and 40 nm process that provide superior performance with a 520 CoreMark score at 120 MHz, and strong power efficiency with a 35 CoreMark/mA score as measured by EEMBC benchmarks.

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.

Optimised for connected industrial environments, the MCUs’ network connectivity features 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.
