General Description The HT819D0 is a single chip LOG-PCM voice synthesizer LSI with 4.2-second voice capacity at a 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. The HT819D0 provides 6 key inputs and 2 programmable FLAG outputs. With a 2.4V~5.0V power supply, a complete synthesized voice playback system can be easily built with very few
The HT82M30A is designed as 2D, 3D 3/5-key PS/2 optical mouse controller. These have serial interface to access the Agilent sensor H2051, H2610, H2620 or the same compatible series sensor. Refer to the datasheets for detailed register descriptions of the Agilent sensors.
