BCM89071A1CUBXGT Datasheet, PDF (12/69 Pages) Cypress Semiconductor – Single-Chip Automotive Grade Bluetooth Transceiver and Baseband Processor

BCM89071 Data Sheet
Block Diagram
– 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 compressing scheme (allows more than two simultaneous A2DP packets and up to five
devices at a time)
• Channel Quality-Driven Data Rate (CQDDR) and packet type selection
• Standard Bluetooth test modes
• Extended radio and production test mode features
• Full support for power savings modes:
– Bluetooth standard Hold and Sniff
– Deep sleep modes and regulator shutdown
• Supports Wide-Band Speech (WBS) over PCM and Packet Loss Concealment (PLC) for better audio
quality
• 2-, 3-, and 4-wire coexistence
• Power Amplifier (PA) shutdown for externally controlled coexistence, such as WIMAX
• Built-in LPO clock or operation using an external LPO clock
• TCXO input and auto-detection of all standard handset clock frequencies (supports low-power crystal,
which can be used during Power Saving mode with better timing accuracy)
• OR gate for combining a host clock request with a Bluetooth clock request (operates even when the
Bluetooth core logic is powered off)
• Larger patch RAM space to support future enhancements
• Serial flash Interface with native support for devices from several manufacturers
• One-Time Programmable (OTP) memory
