1 / 194 page  AS3525-A/-B C22O22 Data Sheet, Confidential © 2005-2009, austriamicrosystems AG, 8141 Unterpremstaetten, Austria-Europe. All Rights Reserved. www.austriamicrosystems.com Revision 1.13 1 - 194 å 1 Description This highly flexible and fully integrated audio processor system (AS3525) combines strong calculating power, high performance audio features with system power management options for battery powered devices. Using advanced 0.13µm process technology and large on chip RAM leads to outstanding low power consumption of as low as 58mW for a complete flash-player during MP3 playback. Based on a powerful ARM9TDMI capable of performing up to 200MIPS it is suited to run MP3, AAC, WMA, OGG… decoders and encoders and, in addition, it can perform extensive user interfaces, motion graphics support, video playback and much more. The AS3525 SOC (system-on-a-Chip) features dedicated high speed interfaces for ATA IDE, USB2.0 HS-OTG and SDRAM ensuring maximum performance for download, upload, and playback. Furthermore interfaces for NAND flashes, MMC/SD cards and Memory Stick ensure most flexible system design possibilities. Hardware support for parallel interfaces lower the CPU load serving complex and/or colour user interfaces. Additional serial high-speed data and control interfaces guarantee the connection to other peripherals and or processors in the system. Two independently programmable PLLs generate the required frequencies for audio playback/recording, for the processor core and for the USB interface at the same time. An additional external clock input eliminates the use of external crystals when used in multi-processor systems like mobile phones. It has a variety of audio inputs and outputs to directly connect electret microphones, and auxiliary signal sources via a 10-channel mixer to a 16 Ω/32Ω headset , 4Ω speaker or auxiliary audio peripherals. Further the device offers advanced power management functions. All necessary ICs and peripherals in a Digital Audio Player with flash or hard-disk memory are supplied by the AS3525. The different regulated supply voltages are fully programmable. The power management block generates 10 different supply voltages out of a single battery supply. CPU, NAND flash, SRAM, memory cards, LCD, LCD backlight and USB-OTG can be powered. When operating from a single cell (AA or AAA) battery the AS3525 can use a DCDC booster to generate the needed system supply. The AS3525 has an independent 32kHz real time clock (RTC) on chip, which allows a complete power down of the system CPU and peripherals. AS3525 also contains a charger for Li-Io battery supply The single supply voltage may vary from 1.0V to 5.5V. 2 Key Features 2.1 Digital Core Embedded 32-Bit RISC Controller • ARM922TDMI RISC CPU • 2.5Mbit on-chip RAM • 1Mbit on chip ROM • Clock speed max. 250MHz (200MIPS) • Standard JTAG interface USB 2.0 HS & OTG Interface • Up to 480Mbit/s transfer speed • USB 2.0 HS/FS physical inlcuding OTG support • USB 2.0 HS/FS digital core including OTG host • Dedicated dual port buffer RAM • DMA bus master functionality IDE Host Controller • Supporting Ultra ATA 33/66/100/133 modes • Programmable IO and Multi-word DMA capability • Dedicated dual port buffer RAM • DMA bus master functionality External Memory Controller • Dynamic memory interface • Asynchronous static memory • DMA bus master functionality DMA Controller • Single Master DMA controller • 2 DMA channels possible at the same time • 16 DMA requests supported Interrupt Controller • Support for 32 standard interrupts • Support for 16 vectored IRQ interrupts Audio Subsystem Interface • Dedicated 2 wire serial control master • I2S input and output with dual port buffer RAM Nand Flash Interface • 8 and 16bit flash support • 3, 4 & 5 byte address support • hardware ECC MMC/SD Interface • MMC/SD Card host for multiple card support • 4 data line support for SD cards Datasheet, Confidential AS3525 Advanced Audio Processor System |
