The CC2541 is highly suited for systems where ultralow power consumption is required. This is specified by various operating modes. Short transition times between operating modes further enable low power consumption.

The simplified block diagram is given below.

The modules can be roughly divided into one of three categories: CPU-related modules; modules related to power, test, and clock distribution, and radio-related modules.
