BC0 5 - MM
The BlueCore05-MM is a single-chip radio and baseband IC for Bluetooth 2.4GHz systems. It provides
a fully compliant Bluetooth system to v3.0+EDR of the specification for data and voice.
BlueCore05-MM contains the Kalimba DSP co-processor with double the MIPS of BlueCore03-MM,
supporting enhanced audio applications. BlueCore05-MM integrates a 16-bit stereo codec and it has a
fully differential audio interface with a low noise microphone bias.
Crystal
The crystal oscillates at 26MHz.
Flash
Flash memory is used for storing the Bluetooth protocol stack and Virtual Machine applications. It can
also be used as an optional external RAM for memory-intensive applications.
Ba lanced Filt er
Combined balun and filter changes the balanced input/output signal of the module to unbalanced signal
of the antenna. The filter is a band pass filter (ISM band).
An t enna
TBM–CBC5 uses ceramic chip anten
na with high dielectric constant, which makes the antenna very
insensitive to surrounding environment and thus gives high design freedom around the antenna.
USB
The USB interface is a full speed Universal Serial Bus (USB) interface for communicating with other
compatible digital devices.TBM–CBC5 acts as a USB peripheral, responding to requests from a Master host
controller such as a Personal Computer (PC).
