CYW20704  
1. Overview  
1.1 Overview  
The Cypress CYW20704 complies with Bluetooth Core Specification, version 4.1+ HS and is designed for use in standard Host Con-  
troller Interface (HCI) UART and HCI USB applications. The combination of the Bluetooth Baseband Core (BBC), a Peripheral  
Transport Unit (PTU), and a Cortex-M3 based microprocessor with on-chip ROM provides a complete lower layer Bluetooth protocol  
stack, including the Link Controller (LC), Link Manager (LM), and HCI.  
1.2 Major Features  
Major features of the CYW20704 include:  
Bluetooth v4.1 + EDR with integrated Class 1 PA  
BT host digital interface (can be used concurrently with below interfaces):  
USB 2.0 full-speed with LPM support (up to 12 Mbps)  
UART (up to 4 Mbps)42  
Integrated RF section  
Single-ended, 50RF interface  
Built-in TX/RX switch functionality  
TX Class 1 output power capability  
RX sensitivity basic rate of –93.5 dBm  
RX sensitivity for Low Energy of –96 dBm  
GCI-enhanced coexistence support, ability to coordinate BT SCO transmissions around WLAN receives  
Supports maximum Bluetooth data rates over HCI and USB interfaces  
I2S/PCM for BT audio  
HCI high-speed UART (H4, H4+) transport support  
Wideband speech support (16 bits linear data, MSB first, left-justified at 4K samples/s for transparent air coding, both through I2S  
and PCM interface)  
Bluetooth SmartAudio® technology improves voice and music quality to headsets  
Bluetooth low-power inquiry and page scan  
Bluetooth low energy (BLE) support  
Supports Cypress proprietary 2 Mbps low energy mode  
Maximum of 127 LE Connections  
Supports TBFC (Triggered Cypress [Bluetooth] Fast Connect)  
Bluetooth packet loss concealment (PLC)  
Bluetooth wide band speech (WBS)  
High-speed HCI UART transport support  
H4 five-wire UART (four signal wires, one ground wire)  
Maximum UART baud rates of 4 Mbps  
Low-power out-of-band BT_WAKE and HOST_WAKE signaling  
VSC from host transport to UART  
Proprietary compression scheme (allows more than two simultaneous A2DP packets and up to five devices at a time)  
HCI USB transport support  
USB version 2.0 full-speed compliant interface with LPM support  
UHE (proprietary method for emulating a human interface device (HID) at system boot up)  
Standard Bluetooth test modes  
Extended radio and production test mode features
