... MSM9845 is a Voice Synthesizer LSI with on-chip FIFO memory. A newly developed synthesis algorithm, OKI ADPCM2, promises superb sound quality. The LSI is fully controllable from an external CPU via 16/8-bit bus interface. MSM9845 is an ideal choice for application systems where such non-microchip data storage as CD ROM is used. FEATURES 16/8-bit Bus Interface On-chip FIFO Memory Capacity : 1024 Bits 16 ms Buffering When Sampling Frequency at 16 ...
