• Manufacturer Part Number: BCM2045
• Description: BLUTONIUM BLUETOOTH 2.0 + EDR SINGLE-CHIP HCI SOLUTION
• Manufacturer: Broadcom Corporation

The Broadcom BCM2045 is a monolithic, single-chip, stand-alone
baseband processor with an integrated 2.4-GHz transceiver for Bluetooth
2.0 + EDR applications. It is fully compliant with the Bluetooth
specification and completely backward-compatible with any Bluetooth
version 1.1 or 1.2-based system. It eliminates the need for external flash
memories and active components by integrating critical components into
the device, thus minimizing the footprint and system cost of
implementing a Bluetooth system.
The BCM2045 EDR solution has been designed in 0.13u bulk CMOS
technology, the most widely available silicon process today. This use of
the advanced process enables the BCM2045 to achieve the lowest
possible current consumption in all modes of operation and maintain the
lowest cost total solution.
The BCM2045 has an architecture that has been designed to take
advantage of the EDR standard. Rather than a modification to an existing
Bluetooth 1.2 radio, the BCM2045 has been optimized to support

Bluetooth 2.0 + EDR. By designing the radio to take advantage of EDR,
higher and more reliable through-and greater-link range performance
can be achieved.
Cost optimized solutions can be achieved with the BCM2045 by using
standard chip-on-board assembly techniques. Low risk applications are
enabled through the extensive integration of external passive and active
components. All sensitive RF and analog portions of the Bluetooth radio
and baseband have been integrated into the device including the most
sensitive high-frequency matching components. This eliminates the
possibility of board level interference and degradation in performance
due to the environment and board level designs. Internal voltage
regulation has been added to eliminate the need for a voltage regulator
and the device is capable of operation using a noisy digital 1.8 to 3.6V
power supply.
