2. GENERAL DESCRIPTION
The ST3011 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 middle bit rate compression (MBRC) for voice
playback and audio playback.
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.
System clock comes from 3MHz crystal or external input.
ST3011 has 32 I/Os and these can be either GPIO or functional
pins. Each pin can be programmed to input or output. One

There are serial and parallel interfaces for various connections
with different MCUs.

Note:
1. If any of OSCXI, OSXO, and ECLK is not used, it needs to connect to GND.
2. The cascade resistor and parallel capacitor on CMD, RD, and WR pins can reduce noise interference. In general, resistor
is short and capacitor is open. Please preserve the options on PCB.
