Functional Description
The Green Voice series is a series of programmable speech synthesizers and melody generators. It provides various sampling rates and beats, tone levels, tempos for speech synthesizer and melody generator. For voice synthesizer, the Green Voice provides 8-bit PCM, 6-bit m-law PCM and 4-bit ADPCM synthesis. In HT85XXX series, a mixed output of two channels PCM synthesis is allowed but only one channel ADPCM synthesis is allowed. For melody generator, the Green Voice supports a tone melody and PCM melody generator and two channels mixed output for the whole series. The Green Voice series build-in 8 programmable I/O pins and 4 programmable input pins along with powerful users command. The users instructions are employed to develop new and customized functions for a wide variety of innovative applications. Speech and melody analysis The speech and melody sources of the Green Voice can be recorded and edited from the PC sound card and media tools. Holteks CAD tools first load a speech source file as .WAV or .PCM format, then transfer the speech file as PCM, LOG-PCM or ADPCM format, and finally save it to the internal mask ROM by changing a layer of the mask. The PCM format generates a higher sound quality whereas the ADPCM format brings about a longer recording capacity. The melody source can either be in the .MID or in the .MLD format. The .MID file is the standard format of the windows media tools. The .MLD file is a text format. After the .MID file is compiled, the .MLD file is automatically generated. The Green Voice can support the following compression format of the voice .WAV and .PCM file: AD4, PCM8, m-law PCM. Current type D/A output The HT85XXX series supply high accuracy current type D/A output pins for audio output. The output volume is changeable from 0 to 15 digital levels by writing a value to the VOLUME registers. The D/A pins are PMOS open drain structure and ouput synthesized signals for driving a speaker through an external NPN transistor when the chip is active. However, it becomes floating when the chip is in the standby state. An 8050 type transistor with hFE=150 is recommended for the output driver of the D/A output pin. Melody/Tone generator The HT85XXX family has a built-in melody/tone generator. The generator can generate 13 different kinds of melody beats, 5 octaves of tone level, 18 tempos, and 2 channels mixed output. Of these components, the melody tempo is changeable and generates sound effects by writing a control value to the TEMPO register. The chip provides the following 18 tempos, 13 beats, and 5 octaves for users programming.

HT85XXX
PCM/ADPCM synthesizer The HT85XXX family contains a PCM and ADPCM synthesizer. The synthesizer offers a wide range of sampling rates from 4kHz to 24kHz for PCM synthesis and 4kHz to 16kHz for ADPCM synthesis. The sampling rate of the synthesizer can be changed by writing a control value to the sampling rate register. It also supports a small variety of 100Hz. For a higher performance sound quality, the PCM coding is required. But for a longer recording capacity, the ADPCM coding is recommended. The capability of the voice sampling rate for various voice compression format. fOSC 4M 5M 6M 8M PCM8 12kHz 15kHz 18kHz 24kHz m-law PCM 11kHz 14kHz 16kHz 22kHz AD4 8kHz 10kHz 12kHz 16kHz For the oscillator circuit, an external resistor is required between OSC and VSS. The oscillator frequency is typically 4MHz for an external resistor of 240kW. The RC type of oscillator offers the most cost-effective solution, although the frequency of the oscillation may vary with temperature and the chip itself due to process variation. ROSC HT84EVA HT84P00 fOSC 4M 5M 6M 8M Mask options The following options have to be defined to ensure a proper system functioning:
* Pull-high resistor: 33kW/98kW (3V) * Key debounce time: 0ms~255ms (fOSC=4MHz)

Oscillator configuration The HT85XXX series provides an RC oscillator for the system clock. The system oscillator stops in the standby state so as to reduce power consumption.
