General 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 can be combined to reach longer voice duration (longer than
2.8 seconds). Customer speech data will be edited and programmed into PLA by changing one mask
during the device fabrication.
