The CC2541-Q1 is a power-optimized true Wireless MCU solution for both low energy and proprietary 2.4-GHz applications. This device enables the building of robust nework nodes with low total bill-of-material costs. The CC2541-Q1 combines the excellent performance of a leading RF transceiver with an industry-standard enhanced 8051 MCU, in-system programmable flash memory, 8KB of RAM, and many other powerful supporting features and peripherals. The CC2541-Q1 is highly suited for systems in which ultralow power consumption is required, which is specified by various operating modes. Short transition times between operating modes further enable low power consumption.
The CC2541-Q1 comes in a 6 mm x 6 mm QFN40 package.
