2. GENERAL DESCRIPTION
The ST3010 is a highly integrated and cost-effective 24-bit
DSP based audio processor for various consumer applications.
It consists of one powerful DSP for advanced voice decoder
and encoder algorithms of natural speech with less memory. It
provides low bit rate compression (LBRC) for voice playback
and audio playback.
System clock comes from 3MHz crystal or external input.
ST3010 has 32 I/Os and these can be either GPIO or
functional pins. Each pin can be programmed to input or output.
One external interrupt pin can be requested by external
devices.
One internal 16-bit DAC can provide significant volume
equipping with internal amplifier. For particular application or
recorder, two general audio interfaces are supported to
interface with external DAC/ADC. Audio interface can be
configured to I2S or Left/Right Justified compatible mode.
There are serial and parallel interfaces for various connections
with different MCUs.
