TEL: 18617042732 ***: 3073924495 The CC2540 is a cost-effective, low-power, true system-on-chip (SoC) for Bluetooth low energy applicati***. It enables robust BLE master or sl***e 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 c***umption is required. Very low-power sleep modes are ***ailable. Short transition times between operating modes further enable low power c***umption.
The CC2540 comes in two different versi***: 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 Bluetoothlow energy solution.
