Speech Synthesizer LSI with on-chip 384K Mask ROM

This version: Mar. 2000

GENERAL DESCRIPTION

The ML2201 is a PCM-based speech synthesizer LSI having an on-chip 384K Mask ROM, D/A Converter and

Low Pass Filter. Utilizing the serial interface enables smaller footprint packaging, which makes the chip an ideal

choice for a pre-recorded message subsystem used with today’s size-critical applications.
