GENERAL DESCRIPTIONS
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.
APPLICATIONS
n Voice memo recorder
n Digital announcer for consumer, industrial, security
n Sound effects generator
and telecommunication products
