CC2540 Bluetooth System-on-Chip

2.4GHz Bluetooth low energy, system-on-chip solution from Texas Instruments

Image of Texas Instruments' CC2540 Bluetooth System-on-ChipTexas Instruments' CC2540 is a cost-effective, low-power, true system-on-chip (SoC) for Bluetooth low energy applications. It enables robust BLE master or slave nodes to be built with very low total bill-of-material costs. The CC2540 combines 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. The CC2540 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.

The CC2540 comes in two different versions: CC2540F128/F256, with 128KB and 256KB of flash memory, respectively.

Features & Benefits
  • One chip device: integrated controller, host and application in 6mm x 6mm package reduces physical size and cost.
  • Flash-based: device firmware can be updated in the field and data can be stored on-chip, increasing flexibility for developers.
  • Complete solution from TI: low-power RF IC, fully embedded single-mode protocol stack, profile software and applications support.
  • RF performance: excellent link budget for long range (up to +97dB) and coexistence with other 2.4GHz devices.
  • Interoperability/compatibility: Bluetooth specification version 4.0 compliant with single-mode (CC2540) and dual-mode devices (BlueLink™ 7.0 Bluetooth/FM single chip solution, WiLink™ 7.0 WLAN/GPS/Bluetooth/FM single chip solution, and WiLink™ 6.0 WLAN/Bluetooth/FM single chip solution), allowing full link testing and development.
