GENERAL DESCRIPTION

The IS22C020 is a high-quality voice synthesizer

with capacity from 16 to 20 seconds. A proprietary

ADPCM algorithm is used. The audio message is

stored in a 512K bit on-chip one-time programmable

memory.

TheIS22C020provideswidevoltageoperatingrange

from 2.4V to 6.0V. A pair of PWM output pins, V^OUT1

and VOUT2, provide direct drive to a buzzer. Voice

quality is comparable to a speaker output and power

consumption is much lower. This facilitates button

battery applications such as greeting cards.

The IS22C020 eliminates the need for complicated

circuitryinvoiceplaybackbutstillachieveshighvoice

quality. Sounds such as human speech, animal

sounds, musical sounds, and even special effects

can be synthesized. Devices can be cascaded to

achieve longer voice duration. Two devices can be

configured in parallel in order to achieve signal mix-

ingwithoutanexternalmixersospeechcanbemixed

withbackgroundmusiceachfromoneoftwodifferent

chips.

A current output pin, C^OUT, enables the device to

driveaspeakerthroughalowcostNPNtransistor.No

complex filtering or amplifier circuit is needed. An

automatic ramp-up and ramp-down function elimi-

nates undesired noise at the beginning and end of

playback.

Up to eight sections are available and accessible

through the S1 to S4 trigger pins. The SBT trigger pin

can be programmed to playback all eight sections or

sequentially from section 1 to 8. An interrupt pin

(IRP), stop pulse (STP) or BUSY signals provide

handshaking with µP or other IS22C020 devices. All

trigger pins give 15 ms debounce time and are ideal

for CDS applications. Two LED drivers are available,

flashing on and off approximately at 3 Hz. The inter-

nal voltage compensated oscillator requires only one

external resistor. Different sampling frequencies are

determined by the external oscillator resistor value.

The instant programming nature of the IS22C020

gives a very short turn around time free of NRE

charges usually required with conventional voice

ROMs. Usersnowcanaddavoicesynthesisfunction

as an additional feature to their products even when

production volume is small. As a result, initial invest-

ment is minimal and the risk in the product develop-

ment phase is reduced.
