CC110LRGPR Visão geral
A sub-1 GHz RF transceiver is a wireless communication IC that both transmits and receives radio signals in the ISM (Industrial, Scientific, Medical) and SRD (Short Range Device) bands below 1 GHz. Within the power and connectivity hierarchy of a system, it sits above a bare RF front end (it contains the full modulator/demodulator and baseband) and below a complete radio module (it still requires a microcontroller for protocol handling). Such transceivers are widely used for low-power wireless links where range, battery life and wall/obstacle penetration matter more than raw data rate.
Key features of the CC110L include a highly configurable baseband supporting 2-FSK, GFSK and MSK modulation, a received-signal-strength indicator (RSSI) down to approximately -120 dBm sensitivity on LCSC product data, and a flexible packet engine with FIFOs for autonomous burst transmission. The device is driven by a standard SPI interface (SCLK, SI, SO, CSn) plus four configurable general-purpose digital output pins (GDO0, GDO1, GDO2) for packet status and clock output.
Architecturally, the CC110L is a true single-chip transceiver: it integrates a low-IF receiver, fractional-N synthesizer, and power amplifier on one die, derived directly from the CC1101 silicon. This makes RF register configurations from the widely documented CC1101 ecosystem (SmartRF Studio, TI reference designs) directly applicable, dramatically shortening firmware development.
Typical applications include 433 MHz / 868 MHz / 915 MHz wireless sensor networks, home and building automation, alarm and security systems, and industrial telemetry, where the CC110L provides a low-cost bidirectional RF link at currents of tens of milliamps during TX.
Design tip: use the TI reference designs and SmartRF Studio register exports, and pay attention to the exposed-pad ground connection and 4-layer PCB stack-up for best RF performance.

Aplicações típicas
CC110LRGPR é adequado para 6 aplicaçãos: Wireless Sensor Networks, Home and Building Automation, Alarm and Security Systems, Industrial Telemetry and Metering, Remote Keyless Entry and Remote Controls, RF Module and Evaluation Designs.
Wireless Sensor Networks
The CC110LRGPR fits battery-powered wireless sensor networks because its sub-1 GHz ISM operation at 433/868/915 MHz delivers significantly better wall and obstacle penetration than 2.4 GHz radios, and receiver sensitivity of approximately -120 dBm supports hundreds of meters of outdoor range with modest antennas. In a typical node, a low-power MCU drives the CC110L over SPI and lets the integrated packet engine with FIFOs handle framing, CRC and address filtering autonomously, so the MCU can sleep between packets. The value-line price point of around $1 makes it economical for networks with hundreds of nodes.
Recomendado
Home and Building Automation
In home automation systems (door/window sensors, wall switches, lighting controllers), the CC110LRGPR provides a reliable bidirectional link in the 868 MHz or 915 MHz band while consuming power only during short TX bursts. The three configurable GDO pins let the designer map packet-received and clear-channel-indicator signals directly to MCU interrupts, simplifying low-latency command handling for actuators. Because RF performance is identical to the CC1101, existing TI reference designs for building automation can be reused directly, cutting time to market for dimmers, thermostat links and presence-sensor networks.
Recomendado
Alarm and Security Systems
Security sensors and alarm panels benefit from the CC110LRGPR's combination of high sensitivity (approximately -120 dBm) and the 433 MHz band's strong building penetration, ensuring smoke detectors and PIR sensors deep inside buildings still reach the panel. The transceiver's address filtering and CRC checking in hardware reduce false alarms from noise or neighboring systems, while GDO0 can gate TX so that wake-on-motion sensors only key the transmitter when an event occurs, preserving coin-cell life for years. Spirometric reliability is further helped by the 2-FSK/GFSK options at low data rates.
Recomendado
Industrial Telemetry and Metering
For industrial telemetry such as tank-level monitors, utility meter reading and machine status reporting, the CC110LRGPR's 779-928 MHz band support allows region-specific deployments from a single hardware design, and its MSK mode supports higher-throughput burst uploads when the node periodically dumps logged data. The -40C to +85C operating range matches unconditioned industrial environments. Designers typically pair the CC110L with an isolated SPI or optocoupled UART interface from the metering electronics to maintain galvanic isolation, using the hardware packet engine to guarantee data integrity over noisy factory floors.
Recomendado
Remote Keyless Entry and Remote Controls
Remote controls for gates, garage doors and keyless entry commonly use 315 MHz or 433 MHz links, both fully inside the CC110LRGPR's 300-464 MHz coverage. The transceiver supports rolling-code protocols through its fast SPI and software-triggered TX strobe commands, and the low-cost value-line pricing suits high-volume consumer remotes. Because the same footprint accommodates the CC1101, a premium bidirectional remote (with feedback display) and a cost-optimized unidirectional remote can share one PCB, differing only in the populated TI part - CC115L for TX-only variants.
Recomendado
RF Module and Evaluation Designs
Module manufacturers and evaluation-board designers use the CC110LRGPR as the core of compact sub-1 GHz radio modules, exploiting TI's documented reference designs such as the Low-Power Sub-1 GHz Wireless Transceiver design with the Anaren A110LR09A module. The exposed-pad VQFN-20 package simplifies 4-layer PCB RF layout with the ground pad soldered to a via-stitched ground plane, and the SPI-compatible command interface lets one firmware base drive both module and chip-down variants. Value-line pricing enables competitive module BOMs for OEM wireless integration.

Notas de projeto
RF layout quality dominates CC110L performance. Connect the exposed pad to a solid ground plane through an array of via stitches directly under the package, keep the crystal within a few millimeters of pins 6/7 with guard grounding, and route the RF_P/RF_N balanced pair to the antenna matching network as a symmetric differential structure. TI's 4-layer reference PCB for the CC1101/CC110L is the safest starting point; deviating from the reference stack-up requires re-verification of the antenna match with a VNA.
Supply the CC110LRGPR from a clean 1.8-3.6 V rail. Place the DCOUPL capacitor (pin 19) close to the pin as specified in the datasheet, since it decouples the internal 1.6 V digital regulator; omitting it is a common cause of register faults and erratic TX. During transmit, supply current arrives in bursts - use local bulk capacitance near pin 14 (AVDD) so the DC-DC or LDO upstream does not see high transient ripple that can modulate the RF spectrum.
Although CC110L RF performance matches the CC1101, it is a value-line part: confirm every advanced CC1101 register feature used in legacy firmware against the CC110L datasheet register map before assuming compatibility. Also verify the regional band plan - the same board tuned for 433 MHz in Asia is not legal in Europe at 868 MHz without reprogramming frequency, channel spacing and deviation settings via SmartRF Studio exports.
