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. Ver 0.7 1/13 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. 2007-06-14 www.DataSheet4U.com ST3010 2.1 Block Diagram Figure 2-1 ST3010 Block Diagram Ver 0.7 2/13 2007-06-14 www.DataSheet4U.com ST3010 3.
