CC1101RGPR

The CC1101RGPR from Texas Instruments is a versatile, low-power Sub-1 GHz RF transceiver designed for a wide range of wireless applications. It supports various modulation schemes including GMSK, 2(G)FSK, 4(G)FSK, ASK, and OOK, offering flexibility for different communication protocols like Proprietary and Wireless M-Bus.

This transceiver operates in the 300-348 MHz, 387-464 MHz, and 779-928 MHz frequency bands. It boasts a maximum transmit power of +12 dBm and a best-case sensitivity of -116 dBm, enabling robust wireless communication. The device features a low RX current consumption of 14.3 mA and a maximum data rate of 0.6 Mbps. Its operating temperature range is -40 to 85 °C.

The CC1101RGPR is housed in a VQFN package measuring 16 mm² (4 mm × 4 mm). Its design incorporates features for frequency hopping systems with a fast settling frequency synthesizer and Automatic Frequency Compensation (AFC). Digital features include on-chip support for sync word detection, address check, flexible packet length, and automatic CRC handling, simplifying system design.

Low-power operation is a key aspect, with a sleep mode current consumption of 200 nA and a fast startup time of 240 µs from sleep to RX or TX mode. It also includes wake-on-radio functionality and separate 64-byte RX and TX data FIFOs for efficient burst mode data transmission.
