CC110LRGPT Présentation
A sub-1 GHz RF transceiver is an integrated circuit that combines a low-IF receiver and a direct upconversion transmitter with a highly configurable baseband modem, forming the physical layer of a wireless link. Within the power-management-free radio hierarchy, it sits below complete RF SoCs (no built-in MCU) and above discrete radio front-ends, and belongs to TI's SimpleLink Value Line family derived from the widely used CC1101.
Key features include a cost-optimized architecture in which RF performance characteristics are identical to the CC1101, a highly configurable baseband modem supporting packet handling, data buffering, burst transmissions, and clear channel assessment (CCA), plus a standard SPI interface (SI, SO, SCLK, CSN) and four general-purpose digital output pins (GDO0, GDO1, GDO2) for FIFO status and clocking. Two CC110L transceivers together enable a low-cost bidirectional RF link.
Technically, the device integrates a low-IF receiver with RSSI measurement and an automatic frequency control loop, and a fractional-N synthesizer covering all three band groups. Sensitivity and output power follow the CC1101 reference designs, so established CC1101 RF layouts and antenna matching networks can be reused directly.
Typical applications include 433 MHz and 868/915 MHz wireless sensor networks, smart metering and AMR endpoints, home and building automation nodes, and low-power remote controls operating under ETSI EN 300 220 or FCC Part 15 band rules.
When designing with the CC110LRGPT, reuse TI reference designs for the RF matching network and keep the exposed pad well-grounded; balun and crystal placement strongly determine range and sensitivity.

Applications typiques
CC110LRGPT convient pour 6 applications: 433 MHz Wireless Sensor Networks, Smart Metering and AMR Endpoints, Home and Building Automation, Remote Keyless Entry and Remote Controls, Industrial Telemetry and Asset Monitoring, Wireless Alarm and Security Systems.
433 MHz Wireless Sensor Networks
The CC110LRGPT fits 433 MHz sensor networks because its 387-464 MHz band group includes the globally available 433.05-434.79 MHz ISM/SRD allocation, and its CC1101-identical RF performance delivers strong link budgets at low data rates. Nodes typically run the transceiver from a 3.3 V rail over SPI to a low-power MCU, using GDO0/GDO2 interrupts for FIFO and packet-status signalling. The configurable baseband modem handles packet framing, CRC, address filtering, and clear channel assessment, reducing MCU firmware complexity. The trade-off versus 2.4 GHz parts is lower data rate in exchange for significantly better range and wall penetration, which is usually the decisive factor for whole-building sensor coverage.
Recommandé
Smart Metering and AMR Endpoints
Automatic meter reading endpoints benefit from the CC110LRGPT's regional band coverage: 779-928 MHz serves 868 MHz (Europe) and 915 MHz (US) metering bands from one PCB design re-tuned by registers. The integrated low-IF receiver with RSSI supports listen-before-talk and channel-clear evaluation required by regional regulations, while burst-transmission support suits meters that wake, report, and sleep. Battery life is preserved because packet handling and buffering are done in hardware, letting the MCU stay in sleep during radio events. Designers should copy TI's 868/915 MHz matching network reference design and validate the exposed-pad grounding, since sensitivity directly determines meter-to-concentrator range in dense installations.
Recommandé
Home and Building Automation
For lighting controls, door locks, thermostats, and wall panels, the CC110LRGPT offers a bidirectional sub-1 GHz physical layer at value-line cost. Two CC110L devices form a complete low-cost RF link per TI's own description, and FSK/GFSK modulation at 433/868/915 MHz penetrates interior walls better than 2.4 GHz alternatives. The SPI-plus-GDO host interface integrates cleanly with any MCU, and the modem's address filtering and packet-handling offload allow star networks of dozens of nodes without heavy firmware. Engineers should plan for clear-channel-assessment-based channel access to coexist with other ISM traffic, and use GFSK with whitening for robust payloads through reinforced-concrete structures.
Recommandé
Remote Keyless Entry and Remote Controls
The CC110LRGPT suits keyless-entry and handheld remote transmitters where the 315 MHz (Japan/US) or 433 MHz (EU/Asia) band group is mandated - both lie inside its 300-348 MHz and 387-464 MHz ranges. OOK modulation minimizes transmit current for coin-cell or AAA-powered fobs, while GFSK gives extra sensitivity when link margin is tight. The configurable modem supports short packet formats with hardware CRC so encryption-heavy rolling-code protocols run efficiently on the host MCU. Because the package is a compact 20-pin VQFN with exposed pad, the radio fits on small fob PCBs; follow the crystal and balun layout rules closely, as fob antennas are inefficient and every dB of sensitivity counts.
Recommandé
Industrial Telemetry and Asset Monitoring
In factories, the CC110LRGPT provides cable-free telemetry for tank levels, machine vibration nodes, and asset tags where 433/868/915 MHz links outperform 2.4 GHz in metallic, cluttered environments. The identical-to-CC1101 RF performance gives predictable range across documented channel plans, and the RSSI output enables per-node link-quality monitoring for maintenance dashboards. Typical topology places CC110L sensor nodes against a CC1101-based gateway with a better antenna. EMI design matters here: keep the transceiver away from variable-frequency drives and switching supplies, use the exposed pad as the sole RF ground reference, and enable CCA so many nodes share a channel without collisions in periodic-reporting networks.
Recommandé
Wireless Alarm and Security Systems
Security panels and wireless detectors rely on the CC110LRGPT because sub-1 GHz links reach detached buildings and basement zones that defeat 2.4 GHz radios, and the 300-928 MHz span covers regional alarm-band allocations. The receiver's RSSI and configurable sync-word detection support supervision signalling, while hardware packet handling with CRC ensures tamper and alarm messages arrive intact. Supercapacitor- or battery-powered detectors benefit from the modem's burst mode: wake, transmit event, return to sleep within tens of milliseconds. For compliance, verify ETSI EN 300 220 or FCC Part 15 duty-cycle limits per region, and use the GDO pins for interrupt-driven reception so panel receivers can multi-channel scan efficiently.

Notes de conception
The exposed pad of the 20-VQFN (RGP) is the primary RF ground return for the CC110LRGPT. Connect it to a solid ground plane with a 4x4 or denser via array directly under the die, and place the AVDD/DVDD decoupling capacitors (100 nF plus bulk) within 2 mm of their pins. Reuse TI's CC1101 reference-design footprint for the balun/matching network - component values are band-specific and the CC110L's RF performance is identical to CC1101, so the same networks apply for 315/433/868/915 MHz.
Place the 26-27 MHz crystal within 3 mm of XOSC_Q1/XOSC_Q2 and keep the loop away from the SPI bus and any switching regulator; the fractional-N synthesizer is phase-noise sensitive and layout-induced spurs directly erode receiver sensitivity. Route the four SPI lines (SI, SO, SCLK, CSN) as a short group away from RF_N/RF_P traces, and use the GDO pins for interrupt-driven FIFO handling rather than polling to minimize bus activity during RX windows.
The CC110L is a Value Line part: while TI states its RF performance is identical to the CC1101, some register-level host features of the CC1101 are not carried over. Firmware written for CC1101 must be validated against the CC110L datasheet register map before treating the two as interchangeable in production. Also verify regional compliance (ETSI EN 300 220 / FCC Part 15) per band and output-power setting; regulatory approval is design-level, not automatic from the chip.
