CC1125RHBT Description

The CC1125RHBT from Texas Instruments is a high-performance RF transceiver with an integrated MCU, designed for sub-1GHz ISM band applications. It operates across multiple frequency ranges (164MHz–192MHz, 274MHz–320MHz, 410MHz–480MHz, and 820MHz–960MHz) with a maximum data rate of 200kbps, making it versatile for various wireless communication systems. The device supports multiple modulation schemes, including 2FSK, 2GFSK, 4FSK, 4GFSK, MSK, and OOK, ensuring flexibility in signal encoding. With a power output of 16dBm and low power consumption (17mA–27mA RX, 26mA–56mA TX), it balances performance and energy efficiency. The SPI interface and 4 GPIO pins simplify system integration, while the 4kB ROM and 256B RAM provide embedded processing capabilities. Packaged in a 32-VFQFN (5x5mm) form factor, it is suitable for surface-mount designs in compact applications.
