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.
