System Integration

UniStone is optimized for a low bill of material (BOM) and a small PCB size. Figure 3 shows a typical application

example.

Figure 3 Example of a Bluetooth System

The UART interface is used for Bluetooth HCI communication between the host and UniStone. When the HCI

UART transport layer is used, four interface lines are needed: two for data (UARTTXD and UARTRXD) and two

for hardware flow control (UARTRTS and UARTCTS). When the HCI Three-Wire UART transport layer is used the

hardware flow control lines are optional. In addition to the standard Bluetooth HCI commands, UniStone supports

a set of Intel-specific commands called HCI+.

Digital audio can either be sent over the HCI interface or over the dedicated PCM/I2S interface. The PCM/I2S

interface is highly configurable.
