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.
