LC786821E Datasheet, PDF (1/35 Pages) ON Semiconductor – Compressed Audio Signal Processor IC

LC786821E
Compressed Audio Signal Processor IC
with USB Host Controller and Bluetooth
■ Overview
The LC786821E integrates ARM7TDMI-S™, USB host processing, SD
memory card host processing, compressed audio decode processing, audio
signal processing 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 for the SD memory card
processing or audio signal processing etc. make the process of external main
microcontroller easier and very helpful to develop a much features/high
performance audio player system.
■ Main Features
1. USB host/device function (Full speed: 12Mbps),
SD memory card host function
2. MP3^*, WMA^*, AAC^*, FLAC^*, SBC^* decoder processing function
3. Audio input functions such as Analog (stereo 3ch)/digital 3ch input
(Sampling rate convertible)
4. Audio processing functions such as 20 bands equalizer (stereo 1ch),
subwoofer processing, high-frequency range extendable filter and etc.
5. Audio output functions such as Electronical Volume output 5 ch
(for LF, LR, RF, RR, SW), or DAC output 3ch (Lch, Rch, SW)
6. ARM7TDMI-S™ as internal CPU core, flash memory for program and
various data storage
7. Bluetooth^* Audio processing/Hands-free function
8. Operational voltage source: 3.3V single power supply
9. Operational temperature: 40 to +85 C
10. Package: QIP100E (1420) Pb-Free and Halogen Free type
