Description

The VP-1000A is an advanced CMOS LSI chip for general purpose voice/sound record and playback applications.It can be interfaced with external SRAM to construct a realtime recording circuitry, or with external ROM or EPROM for playback only applications. When ROM or EPROM is used, the sound must be digitized by using Eletech's VP-880 Voice Development System or VW-1000A Voice EPROM Writer.

The VP-1000A is totally self-contained. It can  access the external memory all by itself without the help from any microprocessor. Although the chip provides only 15 address lines, an external counter can be easily added to extend the memory addressing to virtuely no limitation.Therefore very long message length can be achieved easily. Overall, the VP- 1000A offers high voice quality and flexible memory addressing that no other chips can.
