RF Transceiver ICs

The CC2640F128RHBT transceiver IC provides a secure and efficient connectivity solution for embedded applications, including wireless wearables and a range of connected IoT devices. This device is designed with Bluetooth 5.0 connectivity and a range of wireless features, including packet filtering and encryption. Its low power consumption makes it one of the most energy-efficient Bluetooth low-energy devices currently available.The CC2640F128RHBT is a system-on-chip (SoC) transceiver, offering a combination of microcontroller, radio-frequency (RF), memory, and application-specific peripherals. It includes ancillary equipment to allow an integrated solution in one device.

Application field

The CC2640F128RHBT is used in a variety of applications, including wireless sensors for fitness trackers and medical diagnostic equipment, remote controls, and wearables. It can also be used as part of an Internet of Things (IoT) solution, such as automated lighting or home security. The device is also compatible with many Bluetooth accessories, allowing easy pairing and data transfer.The device\'s low power consumption is particularly suitable for devices operating on a limited energy source, such as a button cell battery. Its relatively small footprint allows for easy integration into smaller devices, such as wearables.

Working principle

The CC2640F128RHBT works by using radio-frequency (RF) to transmit and receive data, using Bluetooth 5.0 protocol. The integrated RF transceiver part transmits, receives, and modulates data into radio signals in the 2.4 GHz ISM band, according to the Bluetooth 5.0 protocol.To achieve a low-energy solution, the device is designed to work with a Directed Receiver (DRx) mode, which periodically turns off the transceiver when it is not required. This helps to reduce energy consumption further.It is also equipped with a range of security features, including an AES-CCM hardware encryption engine, an embedded Public Key infrastructure (PKI) for key exchanges, and a range of packet filtering techniques to detect and prevent outgoing attacks.Finally, the device is designed for easy integration within an application. The available development and testing environment includes the required drivers, run-time libraries, and software examples to help accelerate the implementation of the target application.
