The MSS0271 is a single-chip CMOS LSI demands minimal external components and memorizes voice up to 2.88 seconds (at 6 KHz S.R.) using the MOSEL qualified coding method (MPCM-4). The MSS0271 contains most of the necessary circuit like oscillator, PLA, D/A converter, buzzer buffer, control and timing logic. Therefore, MSS0271 can apply to various voice systems with minimum external parts. Customer speech data will be edited and programmed into PLA by changing one mask during the device fabrication.
