MSSI121 - (MSSI241 / MSSI121) INSTANT VOICE ROM

Download the MSSI121 datasheet PDF. This datasheet also covers the MSSI241 variant, as both devices belong to the same (mssi241 / mssi121) instant voice rom family and are provided as variant models within a single manufacturer datasheet.

Description

The MSSI121/241/241B is an one time programmable CMOS VLSI ASIC that can memorize voice for 7-12 / 13-24 seconds using 6-bit MOSEL qualified coding method (MPCM).

Most of the necessary circuit are built in like oscillator, ROM, DAC and interface logic.

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. A STOP pulse comes.

MOSEL VITELIC MSSI121/241/241B 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. 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. Repeat pin was provided to keep audio output repeating. Built-in power on play function and is programmable.
