The Broadcom BCM2035 is a monolithic single-chip, stand-
alone baseband processor with an integrated 2.4-GHz transceiver
for Bluetooth 1.1 and 1.2 applications. 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 BCM2035 radio transceiver provides enhanced radio
performance to meet the most stringent industrial temperature
applications or the tightest integration into mobile handsets and
portable devices.
The two usage modules show how the BCM2035 can be used in
both USB and UART typical applications.
The BCM2035 is the optimal solution for any voice and/or data
applications that requires the Bluetooth SIG standard Host
Controller Interface (HCI) via either USB or UART and PCM
audio interfaces. The BCM2035 is based on the production and
UnPlugFest proven architecture of the BCM2033 Bluetooth
baseband core (BBC), peripheral transport unit (PTU), and
microprocessor unit (µPU). The µPU stores the lower level
protocol stack in read-only memory (ROM) plus patch random
access memory (RAM) to provide the maximum flexibility.
