Bluetooth Low Energy is a newly developed ultra-low-power Bluetooth transmission standard for the Bluetooth standard organization Bluetooth SIG to cope with competition from other low-power wireless standards. Texas Instruments' CC2540 is a cost-effective, low-power system-on-a-chip (Soc) solution for Bluetooth low-energy applications that makes it possible to build robust network nodes with low overall bill of materials costs.
CC2540 basic characteristics
The CC2540 includes an excellent industry-standard 8051 core RF transceiver, system-programmed flash memory, 8kB RAM and other powerful companion features and peripherals. The CC2540 is ideal for low-power systems, ultra-low sleep mode, and ultra-low power conversion of the operating mode for ultra-low power consumption. The CC2540 has two different versions: CC2540F128/F256, which have 128kB and 256kB flash memory respectively. Connected to TI's Bluetooth low-power protocol stack, the CC2540F128/256 forms a flexible, cost-effective, single-mode Bluetooth low energy solution on the market.

Interoperability/Compatibility: Single Mode (CC2540) and Dual Mode Devices Compliant with Bluetooth Specification Version 4.0 (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 for comprehensive link testing and development
CC2540 program features
The CC2540 Development Kit provides a complete hardware performance test platform and a single-mode Bluetooth Low Energy (BLE) application for a common software development environment. The kit includes two CC2540-based RF evaluation modules, a CC2540-USB dongle, software and hardware prototypes, cables, antennas and documentation that run quickly and easily with the CC2540's Universal Development Board (SmartRF05EB).
The CC2540 evaluation module can be plugged into the SmartRF05EB board (included in the development kit). The evaluation module can be used as a reference module for CC2540 RF IC performance verification and prototyping.
The SmartRF kit and SmartRF packet sniffer can be used with the hardware in the kit (for testing and debugging). The EV kit has an in-circuit debug probe, so no additional hardware tools are required for debugging software running on the CC2540.
The USB 3.2 specification absorbed all prior 3.x specifications. USB 3.2 identifies three transfer rates – 20Gbps, 10Gbps, and 5Gbps.
Key characteristics of the USB 3.2 specification include:
Defines multi-lane operation for new USB 3.2 hosts and devices, allowing for up to two lanes of 10Gbps operation to realize a 20Gbps data transfer rate, without sacrificing cable length
Delivers compelling performance boosts to meet requirements for demanding USB storage, display, and docking applications
Continued use of existing USB physical layer data rates and encoding techniques
Minor update to hub specification to address increased performance and assure seamless transitions between single and two-lane operation
Improved data encoding for more efficient data transfer leading to higher through-put and improved I/O power efficiency
Backwards compatible with all existing USB products; will operate at lowest common speed capability
