GENERAL DESCRIPTION Thanks to newly developed Analog Multi-Level Storage technology, ML2500 stores noncompressed analog source signal directly into on-chip 1M Bit-Cell Flash memory. The result is superb sound quality without noise and distortions introduced through coding/decoding, and impressive long-time record/playback capability up to 256 sec. ML2500 is fully controllable by an external MCU via the industry's standard Serial Peripheral Interface.
