The CC2540T is a cost-effective, low-power, true wireless MCU for low energy applications. It enables robust BLE master or slave nodes to be built with very low total bill-of-material costs, and 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, 8-KB 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 low energy solution.
True Single-Chip BLE Solution: CC2540T Can Run Both Application and BLE Protocol Stack, Includes Peripherals to Interface with Wide Range of Sensors, and so forth.
