CC8521RHAT is one of the RF transceiver ICs produced by Texas Instruments which can be used in multiple applications. This low power, wide frequency range device can communicate with multiple objects even at a great distance. This IC has been specifically designed to provide flexibility and scalability to embedded applications with very low form factor.

Primarily, the CC8521RHAT device is intended to be used in digital wireless communication applications. The core of the device is a 65nm CMOS transceiver with an integrated ARM Cortex-M3 processor to handle communication tasks. The ARM core is coupled with a dedicated low power peripheral and a power amplifier, providing a single low power IC for both digital communication tasks and radio frequency transmissions.

The working principle of CC8521RHAT is simple. Once the RF interface has been setup for communication, it uses the on-chip peripherals to enhance data rate and signal sensitivity. Additionally, upon receiving data from the remote transmitter, it can decode the signals in real-time using its ARM core and extract the actual data sent. Afterward, the on-chip power amplifier is then used to transmit back the data to the remote receiver by boosting the range and increasing the signal strength.

Another notable application of this IC is in the audio/peripheral subsystem. This application mainly involves integrating multiple audio/peripheral sources into a single integrated system. Here, the CMOS transceiver is used to receive data from peripheral components and encode them for digital transmission. The on-chip ARM core then decodes the data and it is then forwarded to the power amplifier for transmission.

In general, CC8521RHAT transceiver IC is a key component of telephone systems and embedded applications. It has been specifically designed for low power and wide frequency range digital communication. Additionally, its ARM core, along with its peripherals and on-chip power amplifier, makes it a highly flexible and scalable IC.
