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
The device targets wireless consumer and HID applications. The CC2545 is tailored for
peripheral devices such as wireless keyboards.
