Additional preview pages of the HT813D0 datasheet.

The HT813D0 is a single-chip LOG-PCM voice synthesizer LSI with 5.6-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 380 words table ROM for key functions Programmable silence length and end-pulse width (minimal end-pulse width is 330µs at a 6kHz sampling rate) 5.6-second voice capacity (based on a 6kHz sampling rate) Controllable volume FLAG1 options:.
End-pulse o.
