wwGENERAL DESCRIPTIONS
wThe VP-1410A Digital Voice Processor is an advanced
mCMOS LSI chip designed for multiple-message playback
applications. It can access up to 10 different messages of
ovariable length stored in external EPROM or ROM chips.
.cMessage 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
Uexpanded to 20, 40 or more.

Digital Voice Processor
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

PIN DESCRIPTIONS
A0 - A16
Output, address bus, expandable by adding a counter.
Note that VP-1410AF does not have A16.
ANG & ANG
Output, differential analog audio signal.
ANGD
Input, analog signal to be connected to the external
comparator output.
C1
Input, internal RC oscillator. If external clock is to be used,
it must be connected to this pin and its frequency 64x the
sampling rate.
CLK DRV
Output, buffered clock signal, a square wave of the same
frequency as the sampling rate.
D0 - D7
Input, data bus.
ENV
Input, to be connected to an external integrator output.
INT
Output, connected to an external integrator to produce
envelope waveform.
GND
Ground.
I/O1 ~ I/O10
Input/output, trigger pin, active low. I/O1 is for message
#1, I/O2 is for message #2 and etc. When the chip is idle
but not under reset, this pin is the trigger input and pulsing
it will put the chip in the "Play" mode and start the message.
Once in the "Play" mode, the pin becomes a "low" output
until the message is over.
R1
Output, internal oscillator pin. Leave un-connected when
using external clock.
READ
Output, active low. It indicates the chip is in the "Play"
mode. This signal is usually used to enable memory output.
RESET
Input, active high. Reset the chip back to the "Idle" mode.
This pin is level sensitive.
TEST
For factory use only, keep it un-connected.
VCC
Input, supply voltage.
