ML2502 General Description
ML2502 is a record/playback LSI that stores analog signal directly into on-chip Flash memory (128Kbit Cell) without digital conversion utilizing new Analog Storage technology. Such unique features as low voltage operability (2.7 ~ 3.3V), no backup requirement and no external MCU requirement makes the ML2502 an ideal choice for handy Voice Memo, Message Card, toys and other consumer applications.
