## Texas Instruments CC256x series
The Texas Instruments CC256x series is currently in its fourth iteration and provides a Classic-only (CC2560), a Dual-mode (CC2564), and a Classic + ANT (CC2567) model. A variant of the Dual-mode chipset is also integrated into TI's WiLink 8 Wifi+Bluetooth combo modules of the WL183x, WL185x, WL187x, and WL189x series.
