RX651 32-Bit MCUs with up to 2MB Flash/640KB SRAM with Various Security Features. Renesas Electronics has added four new RX651 32-bit microcontrollers to its portfolio, in ultra-small 64-pin (4.5×4.5mm) BGA and 64-pin (10x10mm) LQFP packages. by Julien Happich @ eenewseurope.com

This represents a 59% footprint reduction compared to the 100-pin LGA, and a 49% size reduction versus the 100-pin LQFP, claims the company. The 32-bit 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 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.
