General Descriptions

The PT8R1202 is a part of the PTI Bluetooth product

family. It is a DSP processor with the functionality of

both baseband controller providing the Bluetooth

functionality for high data rate, short-distance wireless

communication in the free 2.4GHz ISM band and

digital audio decoder such as MP3 or AC3. Together

with PT8R100X 2.4GHz radio transceiver IC and an

external flash memory, it provides a fully compliant

Bluetooth system for data and voice communications.

PT8R1202 consists of BlueRF RXMODE2/3, 3-wires

radio interface, Bluetooth baseband and bit processor,

PTI proprietary 32-bit hybrid RISC/DSP embedded

processor with 48bit resolution, and USB / UART /

PCM / DAC / I2S / SPDIF / SMC standard interfaces.

The on-chip 32-bit hybrid RISC/DSP embedded

processor is powerful enough to support full rate

Bluetooth data communications as well as full rate

digital audio decoding and includes large enough

embedded SRAM up to 128KByte to support several

applications without external memory, which results in

cost-effective and low-power consumption systems. In

combination with PTI own optimized Bluetooth

baseband, embedded protocol stacks and audio decoder

firmware, it provides a complete cost-effective SOC

embedded solutions such as portable MP3 decoder,

wireless high quality speaker system or headset.
