MSS0287 - VOICE ROM

Datasheet Summary

Description

The MSS0287 is a single-chip CMOS LSI that memorizes voice up to 2.8 seconds using the MOSEL qualified coding method (MPCM).

The chip contains most of the necessary circuit like oscillator, PLA, D/A converter, buzzer buffer, control and timing logic .

Features

  • Single power can operate at 2.4V through 6V. current output can drive 8 ohm speaker with a transistor. Total maximum duration is 2.8 seconds. Speech + mute is about 21.8 seconds. Automatic power down. Repeat function that can repeat up to 8 times. CDS interface is provided. It can not trigger itself by stop pulse. Mask option for either level or edge trigger type. Mask option for LED flasher, BUSY output or STOP pulse output. Mask option for either long (20ms) or short (5ms) debounce time. Mask.
