What the CC1101 family does
The CC1101 is a low-power sub-1 GHz RF transceiver microcontroller designed for wireless sensor networks, automatic meter reading, and home automation in the 315, 433, 868, and 915 MHz ISM/SRD bands. It supports data rates from 0.6 to 600 kbps with sensitivity reaching -118 dBm at 868 MHz and output power up to +12 dBm. The device features a configurable baseband modem, 64-byte FIFOs for burst transmission, and wake-on-radio functionality. It operates with minimal external components, requiring no filters or RF switches, and includes digital RSSI and link quality indication. The CC1101 integrates an on-chip frequency synthesizer and analog temperature sensor, making it suitable for frequency hopping systems and compliance with EN 300 220 and FCC standards.

| Parameter | Min | Typ | Max | Conditions | Source |
|---|---|---|---|---|---|
| supply voltage range | 1.8 V | — | 3.6 V | All supply pins must have the same voltage; 2 Operating Conditions | TI datasheet, p. 8 — 2 Operating Conditions |
| operating temperature | -40 °C | — | 85 °C | High Frequency Ceramic Solutions | TI datasheet, p. 22 — High Frequency Ceramic Solutions |
| operating frequency | 300 MHz | — | 348 MHz | Frequency Coverage | TI datasheet, p. 4 — Table 3. Frequency Coverage |
| output power | — | 12 dBm | — | See Design Note DN013 [15] for output power and harmonics figures when usingmulti-layerinductors. The output power is then typically +10 dBm when operating at 868/915 MHz.; 4.3 RF Transmit Section | TI datasheet, p. 16 — 4.3 RF Transmit Section |
| sensitivity | — | -104 dBm | — | Sensitivity can be traded for current consumption by setting MDMCFG2 . DEMDCFILT OFF = 1. The typical current consumption is then reduced from 17.7 mA to 15.6 mA at the sensitivity limit. The sensitivity is typically reduced to -102 dBm; receiver; 38.4 kBaud data rate, sensitivity optimized, MDMCFG2 . DEMDCFILT OFF = 0(GFSK, 1% packet error rate, 20 bytes packet length, 20 kHz deviation, 100 kHz digital channel filter bandwidth) | TI datasheet, p. 13 — Table 7: RF Receive Section |
| load capacitance | 10 pF | 13 pF | 20 pF | Simulated over operating conditions; 4.4 Crystal Oscillator | TI datasheet, p. 18 — 4.4 Crystal Oscillator |
