Overview
Features
* MP3(MPEG Layer-3 Audio Coding)
* Windows Media Audio
* AAC
* This IC is licensed from United States Silicon Storage Technology, Inc. and is manufactured and sold by SANYO Semiconductor Co., Ltd.
* AViSS is a registered trademark of SANYO Electric Co., Ltd.
The LC786800E integrates ARM7TDMI-S™, USB host processing, SD memory card host processing, Compressed
audio encode/decode processing, Audio signal processing, Electronic volume and a flash memory which stores the
program for ARM7TDMI-S™ and the various data. The sophisticated programs in the flash memory for the USB
host processing or for the SD memory card processing or Electronic Volume control processing, etc. make the load of
external main micro controller to be light and are very useful to develop a much features/high performance audio
player system with less development burden.
• USB host function (Full speed as 12Mbps), SD memory card host function
