Description

The HT812L0 is a single chip PCM voice and sound effect synthesizer. It provides 2.8 seconds of voice capacity at a 6kHz sampling rate (FSR=6kHz) and 32 sections of sound effects/ simple melodies. A maximum of 8 keys or 4´4 MATRIX are available. Of the 8 keys or 4x4 MATRIX, KEY1 can be optioned as a direct or sequential/random key, so that it can play an interlaced voice/sound effect/simple melody and generate various special sound effects for toys and sound effect generator applications.
