Shrinked versions of RX651 IoT uCs reduce PCB footprint
Renesas has introduced four new versions of its RX651 32-bit MCUs supplied in ultra-small 64-pin BGA and LQFP packages. The new lineup expands Renesas’ popular RX651 MCU Group with a 64-pin (4.5mm x 4.5mm) BGA package that reduces footprint size by 59 percent compared to the 100-pin LGA, and a 64-pin (10mm x 10mm) LQFP that offers a 49 percent 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. 

With their feature set, the MCUs enable 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 120 MHz, and strong power efficiency with a 35 CoreMark/mA score as measured by EEMBC Benchmarks.
