MSSI121/241/241B MOSEL VITELIC INSTANT VOICE ROM Features Single power supply can operate at 2.4V through 6V. Current output can drive 8 ohm speaker with a transistor, Vout can drive buzzer directly. The voice content is stored for 7-12 seconds for SI121 ( 13-24 for SI241/241B ) including mute and is single section / phrase and single trigger. Automatic power down. A phrase is composed of repetitive sections. Interrupt function (INTP) stops the audio output at once. An LED function with 3Hz flash is provided to tell the audio status. Repeat pin was provided to keep audio output repeating. Built-in power on play function and is programmable. Programmable option for either Retrigger or not. Programmable option for either Level or Edge trigger type. Programmable option for either Holdable or Unholdable output type. Programmable option for repeat times up to 8 times. Programmable option for either LED display or STOP pulse on LED/STP pin. SI121 can be programmed by MSM9159, MSM9156, MSM9140 & MSM9139. SI241/241B can be programmed by MSM9159, MSM9140. A STOP pulse comes out when audio signal is finished. CDS input interface with 10ms debounce is provided for trigger pin, REP pin and INTP pin.

Most of the necessary circuit are built in like oscillator, ROM, DAC and interface logic. Versatile functions can be performed with minimum external components. Customer voice data will be edited and built in by MOSEL writer in an instant time base.

Piezo buzzer resonant frequency is around 1K Hz. 4. Input switch could be replaced by CDS. 5. VOUT1,VOUT2 are tristate during stand by . 6. If using MSM9159 writer, use its new version MSM9159B to program MSSI121/241/241B chips. Do not use the old version MSM9159 writer. The difference between two version of writer should refer to its data sheet ( PID 330B ). 7. Power on play function plays only one time regardless the number to repeat.
