Overview

The CYW20704UA2KFFB1GT is a monolithic baseband processor and integrated transceiver designed for Bluetooth v5.0 and Enhanced Data Rate (EDR) applications. Built on the ARM Cortex-M3 architecture, it provides a highly integrated solution with a Class 1 Power Amplifier and optimized coexistence support for high-performance wireless connectivity.

Why Choose This Part

This SoC features a large 848 KB flash and 352 KB RAM footprint for complex protocol stacks and application patching. It provides a unique 2 Mbps proprietary low energy mode and high-speed HCI transport via UART or USB, making it versatile for both embedded and PC-hosted wireless applications.

Applications

Wireless Audio Systems
Utilizes SmartAudio technology and I2S/PCM interfaces for high-quality Bluetooth audio streaming and wideband speech.
IoT Gateway Hubs
Serves as a robust Bluetooth and BLE controller with support for up to 127 simultaneous LE connections.
Voice-Enabled Remote Controls
Features low-power inquiry and page scan modes alongside packet loss concealment for reliable voice transmission.
Industrial IoT Coexistence
Employs GCI-enhanced coexistence to operate reliably in environments with high 2.4 GHz interference.

Getting Started

Development is supported through the Infineon AIROC SDK (formerly WICED), which provides the drivers and protocol stacks needed for the Cortex-M3 core. Engineers typically use the CYW20704 evaluation kits alongside a standard high-speed UART or USB interface for HCI-based development.
