Texas Instruments CC2540 2.4GHz BLUETOOTH® System-on-Chip devices are cost-effective, low-power true SoC solutions for Bluetooth low energy applications. The TI CC2540F128 and CC2540F256 SoCs feature 128 or 256KB flash memory and combine an excellent RF transceiver with an industry-standard enhanced 8051 MCU, in-system programmable flash memory, 8KB RAM, and many other powerful supporting features and peripherals. These TI CC2540 SoC devices enable robust BLE master or slave nodes to be built with very low total bill-of-materials costs. The TI CC2540F128 and CC2540F256 are suitable for systems in which very low-power consumption is required.
