GENERAL DESCRIPTION

The IS22C011 is a high-quality voice synthesizer

with capacity from 8 to 12 seconds. A proprietary

ADPCM algorithm is used. The audio message is

stored in a 256K bit on-chip one-time programmable

memory.

TheIS22C011provideswidevoltageoperatingrange

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 IS22C011 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-down function eliminates undesired

noise at the 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 IS22C011 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 compensation oscillator requires only

one external resistor. Different sampling frequencies

are determined by the external oscillator resistor

value.

The instant programming nature of the IS22C011

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.
