L2500B - Brand New Oki Semiconductor IC Chips
-
GENERAL DESCRIPTION
Thanks to newly developed Analog Multi-Level Storage technology, ML2500B stores non-compressed 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. ML2500B 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. ML2500B is a true single-chip solution to record/playback subsystem for use with today’s size-critical electronic products.FEATURES
