VP1410A QuikVoice Sound Chip
* Voice grade audio playback
* Stand alone operation
* CVSD compression with variable sampling rates
* Use external EPROM for sound data storage
* 10 sound segments with direct trigger pins
* Single channel output
* Low power consumption
* Available in PDIP48 and QFP48 packages
VP1410A is a multi-segment sound playback chip which uses
external EPROM for data storage. The chip contains a DAC and can access up to 10 sound segments of different length. Each segment is activated via its own trigger pin. 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.
VP1410A 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,
VP1410A is a low power device suitable for battery operated applications.
For VP1410A 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.
