Overview

The CC1100ERGPR is a high-performance sub-1GHz radio frequency transceiver designed for low-power wireless applications in the 470-510 MHz and 950-960 MHz frequency bands. It features a highly integrated design with an intermediate frequency (IF) processor, a low-noise amplifier (LNA), and a frequency synthesizer, making it suitable for compact wireless links. The device supports multiple modulation formats including 2-FSK, GFSK, MSK, ASK, and OOK with data rates up to 500 kBaud.

Why Choose This Part

This transceiver offers excellent receiver sensitivity of -112 dBm and a wide supply voltage range from 1.8V to 3.6V, with an extremely low sleep current of 0.4 uA. It includes hardware support for packet handling, data buffering, and burst transmissions via a 64-byte FIFO, which reduces the processing load on the host microcontroller. Integrated features like Wake-on-Radio (WoR) and a temperature sensor further simplify ultra-low-power system design.

Applications

Wireless Alarm and Security Systems
Reliable low-power sensing for door, window, and motion detectors in building security.
Automatic Meter Reading (AMR)
Sub-GHz penetration for smart utility meters in residential and industrial environments.
Home and Building Automation
Control of lighting, HVAC, and access systems using robust ISM band communication.
Industrial Monitoring
Wireless sensor networks for collecting data from machinery and environmental sensors.

Getting Started

Development is supported through the Texas Instruments CC1100E-EMK evaluation module kits and the SmartRF Studio software, which provides a GUI for testing RF parameters and generating register settings. The device interfaces with a host microcontroller via a standard 4-wire SPI bus and three general-purpose digital output pins. Engineers should consult the CC1100E datasheet for layout guidelines to ensure proper impedance matching at the RF port.
