The SoCs integrate a microcontroller, 32kB flash and one or two kB RAM on a single die, making them ideal solutions for consumer electronics requiring cost and space efficiency. Examples of such devices include computer peripherals, gaming devices, remote controls and toys. The three SoCs are distinguished by different numbers of general I/O pins and, for USB dongle applications, the CC2544 also comes equipped with a USB interface.
TI is also releasing the CC2543-CC2544DK development kit, which provides a complete hardware performance test platform and software development environment for 2.4 GHz proprietary applications. For more information, visit www.ti.com/rfvalueline-pr. Additionally, for $99, developers can reuse the same base boards and upgrade to a Bluetooth low energy development environment.
The CC2543/44/45 SoCs feature a 2 Mbps data rate, 102 dB link budget and a less than 1uA sleep current with sleep timer running. They are distinguished by different numbers of general I/O pins (with the CC2544 also supporting the USB interface). The three SoCs are over-the-air compatible with CC2500- and CC2510-based products, and the TPS62730 step down converter with bypass mode for ultra-low-power wireless applications. Additionally, developers can upgrade to have more memory or to include Bluetooth low energy support—the latter made possible by easily switching to the CC2540/41 SoCs, which also support Bluetooth low energy applications. Both CC2543/44 and CC2540/41 development kits (DKs) are using the same base-board and IDE.
Availability and Pricing
The 2.4 GHz RF value line is available today through authorized TI distributors. Pricing starts at $1.45 for quantities of 10k. The solutions are packaged in a ROHS-compliant, 5 mm x 5 mm QFN-32.
The new CC2543-CC2544DK development kit is priced at $299.00 and is available on the TI eStore and through authorized distributors.
