What are the key features of CC1151IRHBRG4Q1?
- Automotive-grade (AEC-Q100) qualification for reliable operation in harsh environments
- Ultra-low receive current of 14.3 mA enabling extended battery life in wireless sensor nodes
- Wide frequency range supporting 315/433/868/915 MHz ISM and SRD bands worldwide
- High sensitivity down to -116 dBm with configurable bandwidth for robust link performance
- Integrated hardware support for packet handling, data buffering, burst transmissions, and CRC
What is CC1151IRHBRG4Q1 used for?
The CC1151IRHBRG4Q1 is designed for automotive wireless sensor applications such as tire-pressure monitoring systems (TPMS), remote keyless entry (RKE), and in-vehicle diagnostics. Its AEC-Q100 qualification and wide supply voltage range make it suitable for under-hood and body-electronics modules requiring low-power sub-1 GHz communication. It is also used in industrial and smart-metering designs that demand long-range, low-power RF links across globally accepted ISM frequency bands.

Frequently Asked Questions
What frequency bands does the CC1151IRHBRG4Q1 support?
The CC1151IRHBRG4Q1 supports three selectable frequency ranges: 300–348 MHz, 387–464 MHz, and 779–928 MHz. These cover the most widely used sub-1 GHz ISM and SRD bands worldwide, including 315 MHz, 433 MHz, 868 MHz, and 915 MHz, making it suitable for global deployments without requiring hardware redesign.
Is the CC1151IRHBRG4Q1 suitable for automotive applications?
Yes. The CC1151IRHBRG4Q1 carries AEC-Q100 automotive qualification and the suffix 'Q1' specifically denotes automotive-grade reliability. It is designed for applications such as tire-pressure monitoring (TPMS), remote keyless entry (RKE), and other in-vehicle wireless links that require operation across the full automotive temperature range of –40 °C to +85 °C.
What is the receive sensitivity of the CC1151IRHBRG4Q1?
At 1.2 kBaud with 1% packet error rate, the CC1151IRHBRG4Q1 achieves a receive sensitivity as low as –116 dBm. At higher data rates such as 250 kBaud, sensitivity is typically –98 dBm. The configurable channel filter bandwidth allows designers to trade off sensitivity against interference immunity for their specific application.
What package does the CC1151IRHBRG4Q1 come in, and what is its pricing?
The CC1151IRHBRG4Q1 is housed in a compact 32-pin 5×5 mm QFN (VQFN) package, designated 'RHB'. It is available from approximately $1.72 per unit at volume quantities. The part is in stock and available with worldwide shipping, making it easy to source for both prototype and production builds.
What are common alternatives or pin-compatible parts to the CC1151IRHBRG4Q1?
Texas Instruments' CC1101 is a closely related general-purpose sub-1 GHz transceiver sharing similar RF architecture and register-compatible programming. For higher integration, the CC1312R combines an ARM Cortex-M4F microcontroller with sub-1 GHz RF. If only a receive function is needed, the CC1150 transmitter-only variant reduces BOM cost for one-way links.
