The
BCM2033
is a complete Bluetooth
TM
1.1 compliant, single-
chip Bluetooth solution, integrating the 2.4 GHz fractional-N
radio transceiver and baseband controller. It is an ideal solution
for a wide range of wireless communication and networking
applications, including mobile phones, PCs, laptops, PDAs, and
other peripheral devices.
The radio section of the
BCM2033
incorporates the complete
receive and transmit paths, including PLL, VCO, LNA, PA,
upconverter, downconverter, modulator, demodulator, and
channel select filtering.
The baseband section of the
BCM2033
controls all Bluetooth
functionality from the physical layer radio to the HCI layer. This
includes all bit-level processing, event scheduling, voice/data
flow, and on-chip USB/UART/Audio PCM interfaces.
The single-chip Bluetooth solution is a monolithic component
implemented in a standard digital CMOS process, and requires
minimal external components to provide a low-cost BOM
solution. The
BCM2033
is available in a 64-pin fpBGA for
applications that do not need the external memory busses.
The
BCM2033
supports third-party Bluetooth upper layer
protocol stacks.
The
BCM2033
supports the following interfaces:
•
UART
Supports RXD, TXD, RTS and CTS signals. The UART is
16C550-compatible.
•
PCM Audio Codec Serial Interface
The audio transcoder interface supports 13–16-bit linear
PCM, 8-bit
µ-law,
8-bit A-law and CVSD audio and data
formats. The serial audio interface supports standard audio
CODECs.
•
USB
On-chip USB interface conforms to the full-speed (12 Mbps)
requirements of USB specification version 1.1 with on-chip
USB transceiver.
•
8051 Bus Interface
Accesses 64 KB to 256 KB address space for code and data
with eight GPIO signals.
•
Optional 8-Bit Input/Output Slave Interface
Supports generic and 360-type asynchronous modes.
