The CC2541 is a power-optimized system-on-chip (SoC) for both low energy and
proprietary 2.4-GHz applications. 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, 8-KB RAM, and many other powerful supporting features and
peripherals. The CC2541 is highly suited for systems where ultra-low power consump
-
tion is required. Transition times between operating modes further enable low power
consumption.
