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