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 . Therefore, it can apply to various voice systems with minimum external parts. Several device MSS0287 can be combined to reach longer voice duration (longer than 2.8 seconds). Customer speech data of MSS0287 will be edited and programmed into PLA by changing one mask during the device fabrication.
