DESCRIPTION  
rccAieo.miod The CC2541 is a power-optimized true system-on- chip( SoC) solution for both Bluetooth low energy and  proprietary . 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 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  ultralow 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 QFN40 package, if the USB is not  used on the CC2540 and the / extra / O is not used  on the CC2541. Compared to the CC2540, the  CC2541 provides lower RF current consumption. The  CC2541 does not have the USB interface of the  CC2540, and provides lower maximum output power  in TX mode. The CC2541 also adds a HW  interface. 
The CC2541 is pin-compatible with the CC2533  RF4CE-optimized IEEE 802.15.4 Soc. 
The CC2541 comes in two different versions: CC2541F128/ F256. with 128 KB and 256 KB of flash  memory, respectively.
