VS1000 - Ogg Vorbis Player IC with

USB and NAND FLASH Interface

Hardware Features

Description

• Low-power operation

VS1000 is a single-chip Ogg Vorbis (license-

free audio codec) player and a system-on-a-

chip (SoC) for various control and audio ap-

plications. VS1000 contains a high-perfor-

mance low-power DSP core VSDSP⁴, NAND

FLASH interface, Full Speed USB port, gen-

eral purpose I/O pins, SPI, UART, as well as a

high-quality variable-sample-rate stereo DAC,

and an earphone ampliﬁer and a common

voltage buffer.

• Single input voltage: Internal voltage reg-

ulation for analog, digital, and I/O power

• Operates with a single 12 MHz clock

• Internal PLL clock multiplier

• Power button pin,

software-controlled power-off

• USB Full Speed hardware

• NAND FLASH interface with ECC

• I/O for user interface

• High-quality on-chip stereo DAC with no

phase error between channels

• Stereo earphone driver capable of

VS1000 ﬁrmware implements a default player

that reads and plays ﬁles from NAND FLASH.

The player can be customized or replaced by

boot from NAND FLASH or SPI memory.

driving a 30 Ω load

• Lead-free RoHS-compliant package

Firmware Features

When connected to USB, the ﬁrmware imple-

ments USB Mass Storage Device protocol or

acts as an Audio Device, providing a single-

chip USB headphone application.

• Implements USB Mass Storage Device

and Audio Device

• NAND FLASH handling with error cor-

rection, block remapping, and wear lev-

EarSpeaker spatial processing provides more

natural sound in headphone listening condi-

tions. It widens the stereo image and posi-

tions the sound sources outside the listener’s

head.

elling

• Default player application in ﬁrmware

– Decodes Ogg Vorbis, sound level

normalization using Replay Gain

– Pause / Play

– Volume control

SPI EEPROM can be used to load code in

applications that do not use NAND FLASH.

– Next / Previous Song

– Rewind and Fast Forward

– Random Play

– EarSpeaker Spatial Processing

• Bass and treble controls for customized

player

• NAND FLASH boot for customized player

• SPI FLASH boot for special applications

• UART for debugging and special appli-

cations
