Product details
Overview
CC1100RTKR from Texas Instruments is a low-power sub-1 GHz RF transceiver IC designed for ISM/SRD bands at 315/433/868/915 MHz, featuring –111 dBm sensitivity at 1.2 kBaud, 14.4 mA RX current, and +10 dBm programmable output power. It integrates a configurable baseband modem supporting 2-FSK/GFSK/MSK/OOK/ASK, 64-byte TX/RX FIFOs, and SPI interface control - deployed in wireless sensor networks and AMR systems.
For engineers reviewing the CC1100RTKR datasheet, CC1100RTKR pinout, CC1100RTKR application, or CC1100RTKR equivalent, key selection criteria include its 300–928 MHz frequency agility, wake-on-radio capability, hardware-accelerated packet handling (sync word detection, CRC, LQI), and QLP 4×4 mm 20-pin RoHS-compliant package suited for battery-powered embedded RF designs.
Technical Context
The CC1100RTKR implements a fully integrated RF front-end with on-chip frequency synthesizer (PLL/VCO), low-noise amplifier (LNA), power amplifier (PA), and digital demodulator. Its analog signal chain supports automatic frequency compensation (AFC), programmable channel filter bandwidth (58–812 kHz), and RSSI/LQI generation per packet.
Digital subsystem includes SPI-configurable registers, burst-mode FIFO access, hardware-assisted packet framing (preamble/sync/length/CRC), and low-power modes: 400 nA SLEEP, 240 µs wake-to-RX/TX, and WOR-enabled polling - all coordinated via MCSM0/MCSM1/MCSM2 state machine control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 300–348 MHz / 400–464 MHz / 800–928 MHz - enables single-hardware deployment across global ISM/SRD bands without RF redesign. |
| Receiver Sensitivity | –111 dBm @ 1.2 kBaud, 868 MHz, 1% PER - ensures reliable link budget in low-SNR environments like building penetration or long-range sensor nodes. |
| TX Output Power | Programmable up to +10 dBm - allows precise EIRP tuning to meet regional regulatory limits (e.g., EN 300 220, FCC Part 15) without external PA stages. |
| Data Rate | 1.2–500 kBaud - supports both ultra-low-power telemetry (1.2 kBaud) and high-throughput burst transmission (500 kBaud) in same device. |
| Current Consumption | 14.4 mA RX @ 1.2 kBaud; 400 nA SLEEP - enables multi-year battery life in wake-on-radio sensor endpoints with periodic listening intervals. |
| Modulation Support | 2-FSK, GFSK, MSK, OOK, shaped ASK - provides protocol flexibility for legacy (OOK) and robust (GFSK) wireless standards. |
| FIFO Size | 64-byte TX + 64-byte RX - decouples MCU processing from RF timing, enabling burst transmission/reception without real-time CPU intervention. |
Pinout & Package
CC1100RTKR uses a QLP (Quad Leadless Package) 4×4 mm, 20-pin surface-mount package with exposed thermal pad (EP). Pin numbering follows standard counter-clockwise layout starting from top-left corner (Pin 1), with RF_P/RF_N differential antenna interface, SPI bus (SI, SO, SCLK, CSn), GDO status outputs, and supply/ground pins distributed for noise isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GDO0 | General Digital Output 0 | Configurable status indicator (e.g., sync word detected, packet received, RSSI threshold crossed) - used for interrupt-driven MCU wake-up or LED signaling. |
| GDO1 | General Digital Output 1 | Secondary status output (e.g., carrier sense active, CCA complete, WOR timer expired) - enables dual-event monitoring without polling. |
| RF_P / RF_N | Differential RF Transceiver Interface | Direct connection to balun or differential antenna - eliminates need for external matching network in reference design layouts. |
| SI / SO / SCLK / CSn | SPI Serial Interface | Full-duplex 4-wire SPI (3.3 V tolerant) for register configuration, FIFO read/write, and command strobes - supports burst transfers for efficient register updates. |
| VDD / GND | Power Supply / Ground | Single 1.8–3.6 V supply with dedicated analog/digital ground pins - requires local 100 nF + 1 µF decoupling per supply pair near package edge. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware Packet Engine | On-chip sync word detection, address filtering, variable-length packet support, and automatic CRC generation/checking - reduces MCU firmware overhead and improves packet reliability. |
| Wake-on-Radio (WOR) | Autonomous low-power RX polling using internal RC oscillator and timer - enables <1 µA average system current in listen-before-talk sensor nodes. |
| Fast Frequency Synthesizer | 90 µs settling time - supports rapid frequency hopping and fast mode transitions (e.g., sleep → RX in 240 µs). |
| Programmable Channel Filter | 58–812 kHz digital IF bandwidth - allows trade-off between adjacent-channel rejection and sensitivity based on data rate and interference environment. |
| Link Quality Indication (LQI) | Per-packet LQI value derived from demodulator metrics - enables adaptive retransmission, routing decisions, and mesh network health monitoring. |

FAQ
What is the operating voltage range for CC1100RTKR?
The CC1100RTKR operates from 1.8 V to 3.6 V across all supply pins, with all VDD pins requiring identical voltage. This single-supply architecture simplifies power design in space-constrained battery-powered devices and ensures stable RF performance across wide input voltage swings typical in coin-cell or energy-harvesting systems. The CC1100RTKR maintains full functionality including +10 dBm TX output and –111 dBm RX sensitivity throughout this range.
Does CC1100RTKR support hardware CRC calculation?
Yes, the CC1100RTKR includes dedicated hardware for automatic CRC generation and verification on transmitted and received packets. When enabled via the PKTCTRL0 register, it computes and appends a 16-bit CRC to outgoing frames and validates incoming CRC before asserting GDO0 for packet reception. This offloads CRC processing from the host MCU, reduces firmware complexity, and improves packet error detection reliability - a core feature confirmed in SWRS038D Section 15.5.
What package type and dimensions does CC1100RTKR use?
The CC1100RTKR uses a QLP (Quad Leadless Package) with 20 terminals, measuring 4.0 mm × 4.0 mm × 0.8 mm and featuring an exposed thermal pad (EP) on the bottom. This RoHS-compliant, green package is optimized for high-density PCB layouts and thermal dissipation in compact wireless modules. Pin 1 is located at the top-left corner, and the layout follows TI's standardized QLP-20 footprint documented in SWRS038D Section 34.
Can CC1100RTKR operate in the 915 MHz band?
Yes, the CC1100RTKR is explicitly specified for operation in the 915 MHz ISM band (800–928 MHz range), with verified performance including –111 dBm sensitivity at 1.2 kBaud and 13.5 mA RX current. Its frequency synthesizer supports direct programming across 800–928 MHz, and TI's reference designs (e.g., CC1100EM) validate 915 MHz operation with FCC Part 15 compliance. No hardware modification is required to deploy CC1100RTKR in North American 915 MHz systems.
What is the minimum sleep current of CC1100RTKR?
CC1100RTKR achieves a minimum sleep current of 400 nA in SLEEP state with voltage regulator disabled and register values retained - measured at 25°C with all GDO pins configured to 0x2F (high-impedance). This ultra-low quiescent current enables decade-scale battery life in intermittently active sensor nodes. Wake-on-radio functionality remains available in this state, allowing autonomous polling without MCU involvement until valid RF activity triggers wake-up.
