MOSEL VITELIC MSS0287 VOICE ROM 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 option for either holdable output or not. Mask option for either fixed (6Hz) or dynamic type on LED flasher. Mask option for either retrigger or not. 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.
