Original Texas Instruments CC1101 is a low-cost sub- 1 GHz transceiver designed for very low-power wireless applications. The circuit is mainly intended for the ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency bands at 433MHz, but can easily be programmed for operation at other frequencies in the 387-464MHz bands.

Features:

• CC1101 is the improved version of CC1100
• Low noise operation ensures better and improved adjacent channel power (ACP) performance;
• The saturation level input is higher
• Higher performance power output
• Expansion of the continuous frequency band
• Peripheral circuit devices use 1% high-precision peripheral parameters.
• Designed specifically for 1.2K low-speed baud rate, increasing the communication distance of 1101 model.
• It is smaller and more stable than the ordinary CC1100 module, and at a 1.2K baud rate, the distance is about 50-100 meters.

Specifications:

• Working voltage: 1.8-3.6V
• Working frequency: (module: 387-464MHZ)
• Instantaneous maximum operating current: <30mA
• Maximum transmission power: 10mW (+10dBm)
• ISM band of 315/433/868/915MHZ
• Support 2-FSK, GFSK and MSK modulation methods
• Receive sensitivity is -110dBm at 1200 baud rate
• Minimum working rate of 1.2kbps, up to 500kbps
• Separate 64-byte RX and TX data FIFO buffers
• Built-in hardware CRC error detection ensures reliable data transfer
• Support RSSI strong and weak signal detection and carrier sense function
• Low power consumption (RX, 15.6mA, 2.4kbps, 433MHz
• A suitable frequency hopping system brought by a fast frequency variation synthesizer
• The communication address (256) working frequency can be set by SPI programming
• Programmable control output power, up to +10dBm for all supported frequencies
• The WOR function can set the standby and receive state timing switching time ratio to reduce power consumption;
