The RX260 and RX261 groups of 32-bit MCUs from Renesas feature a capacitive touch sensing unit with high noise immunity and water resistance. These 64-MHz microcontrollers consume 69 µA/MHz when active, dropping to 1 µA in standby mode. With their low-power operation and touch capabilities, the RX260/RX261 MCUs are well-suited for home appliances, building and factory automation, e-bikes, and smart locks.
Based on an RXv3 CPU core, the devices achieve a CoreMark score of 355 at 64 MHz, up to 2.5 times higher than comparable 64-MHz MCUs. Renesas also reports 25% lower active current and 87% lower standby current than similar MCUs, enabling customers to meet strict energy regulations for home appliances and extend the operating time of battery-powered equipment.
The capacitive touch IP (CTSU2SL), included as an HMI function, offers multi-frequency scanning to reduce false detection due to external noise and an automatic judgement function to detect touch events without CPU activation. QE for Capacitive Touch V4.0.0, a development assistance tool, simplifies the initial settings of the touch user interface and sensitivity tuning.
In addition, RX261 microcontrollers feature RSIP-E11A security IP with built-in AES, ECC, and SHA encryption engines and security management features. They also add full-speed USB and CAN FD interfaces.
Both the RX260 and RX261 groups of MCUs are available now from Renesas and authorized distributors.
