FEDL2500-01 FEDL2500-01 This version: Jul. 2000 ML2500 Previous version: Jun. 1999 ¡ Semiconductor ML2500 ¡ Semiconductor Analog-Storage Single-chip Record/Playback LSI with 1M Bit-Cell Flash Memory This document contains minimum specifications. For full specifications, please contact your nearest Oki office or representative. 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. In addition, no backup requirement and low operating voltage (2.7 to 3.3 V) make the LSI an ideal choice for compact, handy and portable terminals. ML2500 is a true shingle-chip solution to record/playback subsystem for use with today's size-critical electronic products.
