ATJ2091H PRODUCT DATASHEET
1. Introduction
ATJ2091H is a new generation single-chip highly-integrated digital multimedia SOC for devices
such as dedicated audio players, photo viewers, PDAs. It includes audio codec, image and video
decoding engine, a high performance 2 core (DSP and MCU) structure with embedded RAM and
ROM, digital record capabilities and USB interface for downloading and uploading. ATJ2091H also
provides an interface to flash memory, LED/LCD/OLED, button and switch inputs, headphones,
microphone while ATJ2091H also can interface to FM input and control. ATJ2091H contains a high
performance DSP, which can easily be programmed to support many kinds of digital audio
standards such as MP3, WMA, etc. As storage devices ATJ2091H can act as a USB mass storage
slave device to personal computer system. ATJ2091H has low power consumption to allow long
battery life and an efficient flexible on-chip voltage converter that allows many different battery
configurations, including 1xAA, 1xAAA, 2xAA, 2xAAA and Li-Lon. The built-in Sigma-Delta DAC
includes a headphone driver to directly drive low impedance headphones. The ADC includes inputs
for both Microphone and Analog Audio in to support voice recording. ATJ2091H also has radio
integration features. ATJ2091H provides a true ’ALL-IN-ONE’ solution that is ideally suited for highly
optimized digital multimedia players.
