Built-in Oscillating Resistor. Single section, 2.79 seconds (4380h). Speech with mute (behind) is up to 21.1 seconds (20000h). Repeat function that can repeat up to 8 times. To turn on LED in sink connection. Automatic power down. www.DataSheet4U.com CDS interface is provided. Mask options Either level or edge trigger type at pin TG. Either LED flasher or BUSY output at pin LED/BZ. Either 6200Hz or 8400Hz S.R. for built-in Rosc. Either holdable output or not. Either retriggerable output or not. Either fixed or dynamic type on LED flasher. Either 3Hz or 6Hz LED fixed flasher, (S.R. dependent). Either Fast or Slow debounce time. General Description 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 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. Customer speech data will be edited and programmed into PLA by changing one mask during the device fabrication.
