Additional preview pages of the HT812D0 datasheet.

The HT812D0 is a single chip LOG-PCM voice synthesizer LSI with 2.8-second voice capacity at 6kHz sampling rate.

The chip when triggered drives a speaker through an external transistor with a current switch D/A converter output.

Negligible current will be consumed in the standby state.

Operating voltage: 2.4V~5.0V Directly drives an external transistor Low standby current (1µA Typ. for VDD=3V) Minimal external components 124 words table ROM for key functions Programmable silence length and end-pulse width (minimal end-pulse width is 330µs at a 6kHz sampling rate) 2.8-second voice capacity Controllable volume FLAG1 options:.
End-pulse output.
3Hz flash.
