In addition to serial data port which can be configured as a UART – with scan path facilities for BlueCore logic, a unique analog a data rate up to 1.5Mbaud, or alternatively as a USB port calibration, alignment and adjustment routine is performed capable of 12Mbaud communications. CSR’s BlueCore IC family provides cost-effective solutions for OEM Bluetooth applications. BlueCore features a unique every time a device powers up. This eliminates the need for ‘single chip’ architecture combining baseband DSP, radio and processor hardware, plus full Bluetooth software on-chip – RF tests and trimming during product assembly, and External interfaces you choose the level of protocol you want to run locally, from the standard host-controller interface to the upper RFCOMM automatically adjusts for drift during day-to-day operation BlueCore devices incorporate a number of interfaces to and SDP layers. to deliver optimum quality links. support efficient system design, including a port for up to 8Mbits of external program memory on some devices, and 2 On-chip RISC processor an I C interface for interfacing with external EEPROM for CMOS platform The benefit of this integration cannot be overstated as RF The use of CMOS provides a fundamental cost/performance BlueCore devices that do not have flash (this could also BlueCore devices are fabricated from CMOS, giving design demands specialist skills which can be a barrier for advantage, allowing CSR to integrate a general-purpose be used for controlling other devices). There is a PCM customers access to the most widely used semiconductor OEMs. Among the innovative techniques employed by CSR processor along with the baseband digital signal codec interface to support voice applications, and eight process in the world. The low cost, security of supply and to realize an ‘RF inside the chip’ design are an image reject processing logic and radio modem – a feat that is typically bits of programmable bi-directional digital I/O. process-scaling benefits resulting from this provide the mixer and near-zero IF which allows the channel filters to too costly on alternative platforms such as BiCMOS. This optimum support to help OEMs succeed in the competitive be implemented in CMOS, and an on-chip VCO including all embedded processor allows a full software implementation Fast-track approval global wireless market. resonant and tuning elements.

There’s even an on-chip voltage regulator which lets minimal die size and power consumption, and because its BlueCore take power from a 5V USB supply. design is netlist-based, making it process-independent. Bluetooth protocol, which can simplify approval for True single-chip design customers. This allows CSR to port BlueCore designs to different CMOS foundries to promote low cost and security of supply, and supports a rapid evolution to smaller geometries. 7 RF COMM Device manager L2CAP Application Application Application RFCOMM/SDP RFCOMM/SDP L2CAP L2CAP LM LM LC LC RF COMM SDP Application support Device manager L2CAP Reg BB H/W +Micro HCI RADIO RADIO BlueCore Link manager BlueCore devices can run the standard host-controller partition, or the full Bluetooth protocol locally.

It allows design to start now, and is ideal for retrofit to embedded systems. We provide an example PCB design for the radio subsystem - all you need to do is decide how to interface it to your product. CSR’s ‘full protocol on BlueCore option eases the software task, reducing the load on the host to a minimum (realizing the 'cable replacement' dreams of Bluetooth's creators). Both UART and USB HCI communications are supported. With the same footprint as BlueCore01, BlueCore01M integrates CSR’s innovative technology with a 4Mbit Flash memory to significantly reduce system implementation size and cost. Effectively requiring minimal system design changes from a BlueCore01 based design but offering dramatic reduction in PCB area, BlueCore01M is available from mid 2001, in both UART and USB versions. In the next generation of BlueCore, flash memory is integrated on chip and released as BlueCore02. Combined with an upgrade to a 0.18µm geometry, this device is both smaller and requires fewer connections than BlueCore01 (49). The resulting module size will shrink dramatically, providing ideal support for full commercial release of mass-market Bluetoothequipped products. As a further enhancement BlueCore02 will be offered in a 4.6mm x 4.6mm chip scale package. The next stage for CSR will be to integrate applicationspecific I/O and programs on-chip - starting with audio codec capability for voicerelated Bluetooth applications in addition to flash memory. This will allow customers to create one-chip BlueCore controlled systems with application-specific firmware. In BlueCore04 an ARM processor will be included to allow more CPU intensive complete Bluetooth profiles and applications to be run on-chip. Bluetooth subsystem requires 2.25cm2 or less PCB area, plus antenna Total Bluetooth subsystem requires 1.5cm2 or less PCB area plus antenna Total Bluetooth subsystem requires 1cm2 or less PCB area plus antenna BlueCore00 “radio only” chip Baseband and RF Integrated Bluetooth protocol - fast route to market BlueCore devices incorporate comprehensive Bluetooth software in the form of embedded firmware. An innovative feature Total Bluetooth subsystem requires 1cm2 or less PCB area plus antenna Optimised only for the cellular phone applications, BlueCore 00 is a ‘radio only’ solution that can be used either with CSR Baseband and LM firmware or third party Baseband solutions integrated into an external host ASIC. Total Bluetooth subsystem requires 1cm2 or less PCB area plus antenna is that BlueCore devices enable users to configure the level of the Bluetooth protocol stack that runs on chip. This provides the option of running the standard Bluetooth configuration with a Host-Controller Interface (HCI) split between the radio subsystem and the host, or the full stack – sending messages via the RFCOMM/SDP layer. Running the full Bluetooth protocol locally on the This allows Bluetooth-equipped products to be brought to BlueCore device – and interfacing via serial messaging - market very rapidly, probably with just a few man-months significantly reduces the load on the host processor, of effort, allowing companies to trial capabilities, and gauge offering major advantages to OEMs. market reaction.

BCSP additionally allows developers to interface at the HCI, L2CAP, RFCOMM, or SDP layers, providing flexibility for companies that have already begun software development. 9 Pre-Qualified Reference Designs for Rapid Time to Market Which provide: Optimized designs modules surface mount on host PCB reference designs with CAD files, test programs approvals: CE, radio type approval, Bluetooth qualification interface.
