Texas Instruments CC2540 2.4 GHz Bluetooth® SoC

Texas Instruments CC2540F128 and CC2540F256 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.

Texas Instruments CC2540DK-MINI Development Kit

Texas Instruments CC2540DK-MINI development kit provides a working reference design for software development of single-mode Bluetooth® low energy (BLE) applications based on the TI CC2540. The included keyfob board operates as a BLE peripheral device and contains modifiable software that can be tailored toward different applications. Using BTool (Windows PC application) along with the included CC2540 USB Dongle, the TI CC2540 BLE stack can be tested and verified while developing custom applications. The TI CC2540DK-MINI development kit contains a CC debugger with mini USB cable, converter board, and 10-pin connector cables.
