n Single 5V DC supply voltage
GENERAL DESCRIPTIONS
The VP-1410A Digital Voice Processor is an advanced
CMOS LSI chip designed for multiple-message playback
applications. It can access up to 10 different messages of
variable length stored in external EPROM or ROM chips.
Message activation is simplified since each message has
its own trigger pin . If memory bank switching technique
is used, the number of messages supported can be easily
expanded to 20, 40 or more.
APPLICATIONS
n Multiple message playback
n Sound effects generator
n Low power consumption
n Internal RC oscillator or external clock
n Continuous Variable Slope Delta (CVSD) modulation
n Sampling rate from 24Kbps to 128 Kbps
n Message digitization with the VP-880 system
n 48-pin DIP (VP-1410A) or 48-pin QFP (VP-1410AF)
The VP-1410A is totally self-contained. It can access the
external memory all by itself without the help from any
microprocessor. Although the chip provides only 16
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-1410A offers high voice quality
and flexible memory addressing that no other chips can.
n Digital message repeaters for consumer, industrial,
security and telecommunication products
