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, VOUT1
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, COUT, 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.
