It provides a fully compliant Bluetooth system to v2.0+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. Balanced Filter 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 . Antenna WT32 uses ceramic chip antenna with high dielectric constant, which makes the antenna very insensitive to surrounding environment and thus gives high design freedom around the antenna. The USB interface is a full speed Universal Serial Bus USB interface for communicating with other compatible digital devices. WT32 acts as a USB peripheral, responding to requests from a Master host controller such as a Personal Computer PC . Synchronous Serial Interface This interface is a synchronous serial port interface SPI for interfacing with other digital devices. The SPI port can be used for system debugging. It can also be used for programming the Flash memory. UART This interface is a standard Universal Asynchronous Receiver Transmitter UART interface for communicating with other serial devices. PCM / I2S / SPDIF Interface Audio Interface The audio interface of WT32 has fully differential inputs and outputs and a microphone bias output. A high-quality stereo audio Bluetooth application can be implemented with minimum amount of external components. Programmable I/O WT32 has a total of 10 digital programmable I/O terminals. These are controlled by the firmware running on the device. Reset WT32 has a reset circuitry that is used to reset the module in the startup to ensure proper operation of the flash memory. Alternatively, the reset can be externally driven by using a WT32 reset pin. Coexistence Interface Dedicated hardware is provided to implement a variety of coexistence schemes. Channel skipping AFH Adaptive Frequency Hopping , priority signaling, channel signaling, and host passing of channel instructions are all supported. The features are configured in firmware. Since the details of some methods are proprietary e.g. Intel WCS , please contact Bluegiga Technologies for details. 3 Electrical Characteristics Absolute maximum ratings Storage temperature Operating temperature VDD_IO VDD_BAT VDD_CHG Terminal voltages
