CC2540的参数如下
he CC2540 is a cost-effective， low-power， true system-on-chip (SoC) for Bluetooth low energy applications. It enables robust BLE master_or slave nodes to be built with very low total bill-of-material costs. The CC2540 combines an excellent 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 CC2540 is suitable for systems where very low power consumption is required. Very low-power sleep modes are available. Short transition times between operating modes further enable low power consumption.
The CC2540 comes in two different versions: CC2540F128/F256， with 128 and_256 KB of flash memory， respectively.
Combined with the Bluetooth low energy protocol stack from Texas Instruments， the CC2540F128/F256 forms the market’s most flexible and_cost-effective single-mode Bluetooth low energy solution.
