CMOS LSI
Compact Disc Player IC
http://onsemi.com
Overview
The LC786961W integrates ARM7TDMI-S™, CD servo control, CD signal processing, compressed audio decode
processing, audio signal processing, USB host processing, SD memory card host processing and a flash memory to
store the program for ARM7TDMI-S™ and various data in a package. Furthermore, various kinds of interface
functions such as SIO, UART etc. reduce the external main controller’s processing load and make high performance
and much functional CD player system, using with less components.
Features
RF signal processing for CD-DA/R/RW, servo control, EFM signal processing, and anti-shock processing
MP3*, WMA*, AAC* decoder processing
Sampling rate convertor, High frequency compensation filter and other various audio signal processing
USB host function (Full speed as 12Mbps), SD memory card host function
ARM7TDMI-S™ as internal CPU core, flash memory for program and various data storage
Operating voltage: 3.3V typical
Operating temperature: 40C to +85C
Packages: SQFP144 (20 20)
