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. The IS22C011 eliminates the need for complicated circuitry in voice playback but still achieves high voice 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 mixing without an external mixer so speech can be mixed with background music each from one of two different chips. The instant programming nature of the IS22C011 gives a very short turn around time free of NRE charges usually required with conventional voice ROMs. Users now can add a voice synthesis function as an additional feature to their products even when production volume is small. As a result, initial investment is minimal and the risk in the product development phase is reduced. The IS22C011 provides wide voltage operating range 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. A current output pin, COUT, enables the device to drive a speaker through a low cost NPN transistor. 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 P 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 internal voltage compensation oscillator requires only one external resistor. Different sampling frequencies are determined by the external oscillator resistor value.
