• Manufacturer Part Number: BC41B143A-ANN-E4
• Description: Bluecore 4-rom CSP EDR Single Chip Bluetooth v2.0 + EDR System
• Manufacturer: ETC

8.6.6
This is a full speed Universal Serial Bus (USB) interface for communicating with other compatible digital devices.
BlueCore4-ROM CSP acts as a USB peripheral, responding to requests from a master host controller such as a
PC.
8.6.7
This is a serial peripheral interface (SPI) for interfacing with other digital devices. The SPI port can be used for
system debugging.
8.6.8
This is a standard Universal Asynchronous Receiver Transmitter (UART) interface for communicating with other
serial devices.
8.6.9
The Audio Pulse Code Modulation (PCM) Interface supports continuous transmission and reception of PCM
encoded audio data over Bluetooth.
8.7
The microcontroller, interrupt controller and event timer run the Bluetooth software stack and control the radio
and host interfaces. A 16-bit Reduced Instruction Set Computer (RISC) microcontroller is used for low power
consumption and efficient use of memory.
8.7.1
BlueCore4-ROM CSP has a total of 13 (11 digital and 2 analogue) programmable I/O terminals. These are
controlled by firmware running on the device.
8.7.2
Dedicated hardware is provided to implement a variety of coexistence schemes. Channel skipping AFH, priority
signalling, channel signalling and host passing of channel instructions are all supported. The features are
configured in firmware. Since the details of some methods are proprietary (for example Intel WCS) please contact
CSR for details.
