It enables robust network nodes to be built with low total bill-of-material costs. The CC2541 combines the excellent performance of a leading RF transceiver with an industry-standard enhanced 8051 MCU, in-system programmable Flash memory, 8-KB RAM, and many other powerful supporting features and peripherals. The CC2541 is highly suited for systems where ultra-low power consumption is required. This is specified by various operating modes. Short transition times between operating modes further enable low power consumption. The CC2541 is pin-compatible with the CC2540 in the 6-mm × 6-mm QFN-40 package, if the USB is not used on the CC2540 and the I2C/extra I/O is not used on the CC2541.
