Renesas Electronics announced four new RX651 32-bit microcontrollers (MCUs) supplied in tiny 64-pin BGA (4,5 x 4,5 mm) and LQFP (10 x 10 mm) packages. 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 increase in endpoint devices operating at the edge has increased the need for secure over-the-air (OTA) firmware updates. 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 MCUs are based on the high-performance RXv2 core and 40 nm process that provide high performance with a 520 CoreMark score at 120 MHz, and strong power efficiency with a 35 CoreMark/mA score as measured by EEMBC benchmarks.
