consists of six types memories : XMEM0, XMEM1, Peripheral Interface block

XMEM2, YMEM0, YMEM1, and YMEM2. All memories

can be byte accessible as general purpose data memory.

Some memories such as XMEM2 and YMEM2 have special

usage. XMEM2 is used as 16KB memory for

communication with Bluetooth baseband hardware or USB,

and YMEM2 is used as 16KB memory for communication

with audio data buffer for stereo PCM output.

PT8R1202 has several peripheral interface such as off-chip

memory interface, USB interface, UART interface, PCM

interface, I2S and SPDIF interface, JTAG interface, Flash

Memory/Card interface, and up-to 59-general purpose

programmable I/O(GPIO) interface. All peripheral devices

are connected to on-chip microcontroller via internal

peripheral bus(V6PB), which is compatible with Advanced

PT8R1202 can boot from NOR type flash and NAND type Peripheral Bus(APB) from ARMâ¢

flash memory. With NOR type flash memory, code can be

cached into internal instruction cache in order to execute

code at high frequency and reduce power consumption of

frequent memory fetch. With NAND type flash memory,

both code and data are stored same memory, which results

in the reduction of system BOM and form factor. If

PT8R1202 boots from NAND flash, the configuration of the

Off-chip memory interface supports 4 devices concurrently

such as flash memory, SRAM, and I/O for code and data. It

supports 2MB address space and 16bit data with byte access

functionality. The access timing for each device can be

programmable by software. Also, PT8R1202 supports

external I/O with explicit wait signal such as PCMCIA card.

internal instruction cache is optimized to support NAND

flash efficiently.

USB interface supports both 12Mbps and 1.5Mbps serial

data communication conforming to universal serial bus

standard version 1.1. It supports both device and host side

Software development environment

operation and all operation modes such as bulk, interrupt,

The PT8R1202 supports high-level programming

development with our optimized C compiler based on GCC

and intrinsic library functions to maximize the software

development productivity. The system software to support

application software development includes C-compiler,

multi-level instruction set simulator, performance analyzing

control and isochronous mode. It consists of one control

end-point, four receiver end-points and four transmit end-

points, each of which has dual 64bytes FIFO except control

end-point and supports bulk, interrupt, and control, and two

pair of end-points which supports isochronous mode up to

1023bytes.

profiler, memory configuration optimizer and power On-chip UART supports programmable baud rate up to

monitor. Specially, our C compiler supports automatically maximum 1.84MBaud serial communication and fully

collaboration mechanism between compiled general code programmable serial interface such as flow control and bit

and hand-written DSP libraries to maximize the utilization format. It includes separate 16-byte transmit and receiver

of V6 advanced features.

FIFOs to reduce CPU interrupts.

To reduce the system developing cost, PTI provides

performance optimized DSP library for enabling several

multimedia standards with our own developing skill for

multimedia application. This library supports several

standards such as MPEG-1/2 layer I, II, III audio

decompression, Dolby Digital decompression, WMA, SBC

codec, G.723.1/G.728 speech codec, etc.

Advanced audio streaming on Bluetooth

PT8R1202 supports advanced audio streaming using the

advanced audio distribution profile(A2DP) defined in

Bluetooth. This profile is used by devices to distribute audio

content of high-quality in mono or stereo on ACL channels,

as well as Bluetooth audio which indicates distribution of

narrow band voice on SCO channel. PT8R1202 support

several codecs in A2DP such as low complexity subband

codec(SBC), MPEG-1,2 audio, or WMA. This advanced

audio streaming feature of PT8R1202 can be used several

audio system with Bluetooth connectivity between portable

audio player and headphone, high-quality audio system and

surround speaker, or portable speech recorder and

microphone.

For supporting A2DP, PT8R1202 embeds all Bluetooth

stack such as baseband, LMP, L2CAP, SDP, AVDTP(A/V

Distribution Transport Protocol) and AVCTP(A/V Control

Transport Protocol). As well as A2DP, PT8R1202 supports

cordless phone or dial-up networking using RFCOMM,

TCS/BIN protocol and profiles.

PT0137(08/04)

PCM interface supports the external PCM codec with

CVSD Bluetooth codec functionality. For the external PCM

codec, it support 8-bit A/u-law PCM and 13- or 14-bit

8KHz linear PCM in both master or slave mode. For 8-bit

A/u-law format, it supports one, two and four channels

simultaneously.

Audio output interface supports I2S digital audio interface,

SPDIF digital audio interface. For external DAC, it supports

32, 44.1, or 48KHz sampling frequencies with the

programmable bit resolution up to 24bit. All sampling

frequency can be generated both from on-chip audio PLL or

external clock source.

Audio input interface supports both I2S interface and SPDIF

interface with 32, 44.1, or 48kHz sampling frequencies. For

slave mode in which all control signals come from external,

I2S interface can support up to 192kHz sampling frequency.

PT8R1202 supports the dedicated hardware interface to

SmartMediaâ¢ flash memory(NAND type) or card. Without

the occupation of the CPU resource, it supports DMA

transfer for SmartMediaâ¢ interface to achieve fast

read/write operation. At SMC boot mode, PT8R1202 can

boot from SMC without normal parallel flash of NOR type.

PT8R1202 provides 59-bit programmable, bi-directional

IO(GPIO) which are shared with dedicated pins in order to

reduce pins. GPIO signal can be used as key-pad input,

MMC/SDCard/Memory Stickâ¢ interface, or LCD interface.
