The CC2540T device is a cost-effective, low-power, true wireless MCU for Bluetooth low energy applications. The CC2540T enables robust BLE master or slave nodes to be built with very low total bill-of-material costs, and it can operate up to 125°C. The CC2540T combines an excellent RF transceiver with an industry-standard enhanced 8051 MCU, in-system programmable flash memory, 8KB of RAM, and many other powerful supporting features and peripherals. The CC2540T 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.

Combined with the low energy protocol stack from Texas Instruments, the CC2540TF256 forms the market’s most flexible and cost-effective single-mode Bluetooth low energy solution.
