INTRODUCTION
M5705 ALi's high-integration solution DVD-player systems. includes microcontroller, DVDDecoder, CD/CD-ROM Decoder, buffer I/F, microcontroller I/F, ATAPI I/F, data channel digital servo controller. M5705 support CD-ROM DVD-ROM systems. This highly integrated chip playback only standard format DVD-ROM DVD-R disk, also various CD-ROM disk types such CD-DA, VCD, CDI, Photo Karaoke CD-plus, Enhanced CD-R etc. M5705 configured with signal processor (for example, M5703 M5707), audio DAC, buffer, motor drivers create DVD-ROM system (refer following figure). also integrates MPEG-2 interface so-called local bus) designed into ATAPI based local based player easily. M5705 decoder blocks highly automatic that system maker just needs little effort control data transfer flow. decreases complexity size firmware. These automatic features include Automatic error handling procedure When errors occur, hardware will turn related blocks adjust pointers automatically. Firmware does have take care these activities. Auto count target :The hardware will calculate re-seek Q-code/ID target automatically. Hardware will execute some ATAPI protocols automatically reduce firmware loading. M5705 supports realtime CD-ROM C1/C2/C3 error correction. M5705's digital servo implements focus, tracking, sledge spindle servo loop. also provides auto-adjustment method. Based this chip, system manufacturers design adjustment-free CD/DVD systems easily. M5705 also provides stable layer jump solution reading data from dual layer discs. This feature makes playback smoothly even point layer change. M5705 includes embedded microcontroller which compatible with Intel 8032. also provides external microcontroller interface customers evaluate develop DVD-player system easily with M5705. external microcontroller interface supports variety microcontrollers, such those Intel's Motorola's. M5705 supports automatic system firmware download function that system user upgrade system firmware directly from interface CD-R discs recorded with version firmware. even flash system that firmware code user directly download firmware specific command procedure through ATAPI interface. interface transfer data Programmed (PIO), mode. local signals directly connecting MPEG decoder share pins with interface. buffer memory implemented with DRAM device. Both SDRAM used. buffer manager programmable provide necessary address control signals DRAM devices varying access times memory configurations. buffer interface 16-bit data bits DRAM directly addressed M5705. package M5705 208-pin PQFP 176-pin LQFP. 208-pin package configured pin-to-pin compatible with previous generation M5701.
