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

9
BlueCore4-ROM CSP is supplied with Bluetooth v2.0 + EDR compliant stack firmware which runs on the internal
RISC microcontroller.
The BlueCore4-ROM CSP software architecture allows Bluetooth processing and the application program to be
shared in different ways between the internal RISC microcontroller and an external host processor (if any). The
upper layers of the Bluetooth stack (above HCI) can be run either on-chip or on the host processor.
9.1
In the implementation shown in Figure 9.1 the internal processor runs the Bluetooth stack up to the Host
Controller Interface (HCI). The Host processor must provide all upper layers including the application.
