Texas Instruments CC2541 2.4-GHz Bluetooth® System-on-Chip (SoC) is a power-optimized true SoC solution for both Bluetooth low energy and proprietary 2.4-GHz applications. TI CC2541 enables robust network nodes to be built with low total bill-of-material costs. CC2541 combines the excellent performance of a leading RF transceiver with an industry-standard enhanced 8051 MCU, in-system programmable flash memory, 8KB RAM, and many other powerful supporting features and peripherals. CC2541 is highly suited for systems where ultralow power consumption is required. This device is specified by various operating modes. Short transition times between operating modes further enable low power consumption.
