Description
The MSSnn07 is a single-chip CMOS VLSI ROM that can memorize voice data up to nn seconds using MOSEL qualified coding method (5-bit MPCM) at 6.00 KHz in 32 sections with arbitrary length.
Both the volume and pitch can be masked and different for each entry each sentence. 5 versatile outputs are available through programmable logic array. With minimum external components, this chip can be applied to various application. Customer voice data will be edited and programmed into ROM by changing one layer of mask during fabrication.

Features
■ Single power supply can operate at 2.4 V through
   6.0 V.
■ Current output can drive 8 ohm speaker with a
   transistor.
■ The voice content can be separated to 32 sections.
■ Duration of each section can be different and is
   multiples of 100 h.
■ Duration of sections with appended memory-less
   mute is up to 21.8 seconds (20000h).
■ 3 straight trigger pins are provided TGA, TGB, TGC.
   Each cross can access a sentence.
■ 4 x 4 matrix trigger crosses are provided by RW1-4,
   K1-4. Each cross can access a sentence.
■ Each sentence is composed of one or more sections.
■ Lower key priority is provided for straight inputs
   and matrix cross inputs.
■ Last key priority is provided for straight inputs.
■ First key priority is provided for 4x4 crosses.
■ Up to 512 table entries for all 32 sentences.
■ Auto ramp up / ramp down & sleep functions are
   built in.
■ INT(interrupt) function is provided.
■ OKY function is provided optionally chipwise.
■ Play all OKY is provided optionally chipwise.
■ Random Play OKY is provided optionally chipwise.
■ Playnext OKY is provided optionally chipwise.
■ Continuous S.W.A.I. OKY is provided optionally
   chipwise.
■ Home S.W.A.I. OKY is provided optionally chipwise.
■ 5 output pins are provided.
■ 20 ms debounce is provided.
■ Sink LED is provided. (Continue ...)
