1.3 Description
The CC2541-Q1 is a power-optimized true Wireless MCU solution for both Bluetooth 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.
