The CC2545 is an optimized system-on-chip (SoC) solution with data rates up to 2Mbps built with low bill-of-material cost. The CC2545 combines the excellent performance of a leading RF transceiver with a single-cycle 8051 compliant CPU, 32-KB in-system programmable flash memory, up to 1-KB RAM, 31 General-Purpose I/O pins and many other powerful features. The CC2545 has efficient power modes with RAM and register retention below 1 µA, making it highly suited for low-duty-cycle systems where ultralow power consumption is required. Short transition times between operating modes further ensure low energy consumption.
The CC2545 is compatible with the CC2541/CC2543/CC2544. It comes in a 7-mm × 7-mm QFN48 package, with SPI/UART/I2C interface. The CC2545 comes complete with reference designs from Texas Instruments.
The device targets wireless consumer and HID applications. The CC2545 is tailored for peripheral devices such as wireless keyboards.

SmartRF™ Studio is a Windows application that can be used to evaluate and configure Low Power RF devices from Texas Instruments. The application helps designers of RF systems to easily evaluate the radio at an early stage in the design process. It is especially useful for generation of configuration register values and commands, and for practical testing and debugging of the RF system. SmartRF Studio can be used either as a standalone application or together with applicable evaluation boards or debug probes for the RF device.
