Description

The MSS6605 is a single-chip CMOS VLSI ROM that can memorize voice up to 60

seconds using

MOSEL qualified coding method (MPCM) at 5.8 KHz.

Three addressing interfaces are provided: CPU mode, KEYBOARD mode and MATRIX mode for versatile

applications. The voice content can be

stored separately into 128 sections or 50 or 56 sentences with

arbitrary length. 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 mask during fabrication.
