VP1606 QuikVoice Sound Chip
* Voice grade audio playback
* Stand alone operation
* CVSD compression with variable sampling rates
* Use external EPROM for sound data storage
* 64 sound segments with binary code control
* Single channel output
* Low power consumption
* Available in PDIP48 package
VP1606 is a multi-segment sound playback chip which uses
external EPROM for data storage. The chip contains a DAC and can access up to 64 sound segments of different length. Each segment is controlled by a 6-bit binay code. Memory addressing is handled by the chip itself. No
microprocessor control is needed. Simple logic pulses are used to start/stop the playback operation. A basic design can be constructed with the chip and a few more components.
VP1606 employs the Continuously Variable
Slope Delta (CVSD) compression technique with variable sampling rates from 24 to 128 Kbps. Samping clock can be generated internally with a simple R/C network, or an external clock can be used. Operated with a single 5V supply,
the VP1606 is a low power device suitable for battery operated applications.
For VP1606 based designs, VP880 QuikVoice Development System must be used for sound development. VP880 is a computer based sound digitization,
editing and management system. After the sound is developed, it is programmed into EPROM chips with a standard EPROM programmer. Eletech also provides sound development and programming service to customers who do not want to do
it themselves.
Applications
* Message repeater
* Sound effects generator
* Gaming, vending and amusement equipment
