The new RX261/RX260 MCUs.
Renesas developed the RX260 and RX261 groups of MCUs to deliver a balance of power efficiency and computational performance.
RX261/RX260 Group Compute
Renesas has designed the new MCUs around a powerful 32-bit RXv3 CPU core, capable of operating at up to 64 MHz. This CPU is equipped with advanced digital signal processing (DSP) capabilities, including 32-bit multiply-accumulate instructions, a 16-bit multiply-subtract instruction, and a 32-bit floating point unit (FPU) that adheres to the IEEE-754 standard. These features enable the MCUs to efficiently handle complex calculations and signal processing tasks, making them ideal for applications in smart home systems, HVAC controls, and security infrastructure.
