Description

The AS3536 is austriamicrosystems´ third generation mobile entertainment platform digital audio/video processor. Its highly flexible architecture allows single chip solutions for high performance power optimised audio and video products with minimum count of external components.

For video applications the integrated video decoder hardware will provide high efficient video decoding at very low clock rates and the speed of the system can be scaled to the actual demanded video decoder complexity and resolution. All video decoder features for H.263/ MPEG-4/H.264 and VC-1 are implemented in a dedicated video hardware accelerator for minimal power consumption.

Using low power deep submicron technology gives outstanding performance in terms of power consumption and utmost integration densities for embedded on-chip RAM and ROM areas.

The AS3536 is intended as a microcontroller chip including all digital function blocks necessary for a portable audio or video player. These function blocks include onchip RAM and ROM memories, interface blocks for data transfer and storage like USB, IDE, NandFlash, MMC, SD, SDIO, CE-ATA.

Based on the ARM926-EJ with large on-chip instruction and data caches and integrated MMU, the system gives full support for all kinds of operating systems from simple RTOS implementations up to Symbian OS, micro Linux and Windows CE.

The AS3536 contains an ultra low power stereo audio codec. It allows playback in higher than CD quality and recording in FM quality. It has a variety of audio inputs and outputs to directly connect electret microphones, 16 /32 headsets and auxiliary signal sources via a 3-channel mixer.

Further the device offers advanced power management functions. All necessary ICs and peripherals in a Digital Audio Player are supplied by the included AFE. The AFE also contains a Li-Ion battery charger. The single supply voltage may vary from 2.7V to 5.5V.

The AFE has an independent 32kHz real time clock (RTC) on chip which allows a complete power down of the system CPU.

austriamicrosystems provides a total system solution reference design including all necessary software blocks for low level HW drivers, device IO functions and a dedicated reference application with common audio and video features.
