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.

Features

■ Single power can operate at 2.4V through 6.0V.

■ Current output could drive 8 ohm speaker with a transistor, Vout could drive buzzer directly.

■ The voice content is stored up to 60 seconds at 5.8 KHz (55500h) for S6605 and can be separated to 128 sections. See next page for other devices data.

■ Duration of each section can be different and is multiples of 100h.

■ Total duration of all 128 sections with mute is up to 96 seconds (80000h).

■ The voice content can be accessed in Sentence type on KeyBoard (KBD) and Matrix(MTX) modes. Up to 50 Sentences for KeyBoard, 56 Sentences for Matrix modes.

■ Each sentence is composed of one or more than one section(s).

■ Automatic power down .

■ Three addressing interface modes are provided for versatile applications: CPU, KBD and MTX.

■ KeyBoard addressing mode:

a. 50 sentences can be accessed by 15 addressing input dual-tree type trigger.

b. Sentence is numbered by 00 through 49.

c. 5 input pins on D-tree (D0-D4) tells the 1st digit (0 through 4), another 10 input pins on S-tree (S0-S9) tells the 2nd digit (0 through 9). By these two digits,all 50 sentences can be accessed.

d. With 2nd digit only also can access a sentence.

e. Section is located and numbered by 0 through 127.

f. Total section number of all sentences is up to 256.

■ Matrix addressing mode:

a. 56 sentences can be accessed by 8x7 wiring matrix.

b. Sentence is numbered by 00 through 55.

c. Section is located and numbered by 0 through 127.

d. Total section number of all sentences is up to 256.

■ CPU addressing mode:

a. 128 sections can be accessed by 7 address bits with an enable strobe trigger.

b. Section is located and numbered by 00 through 127 .

■ Power on trigger play is available by bonding VSS and trigger together.

■ A dedicate LED output pin with 6 Hz flash is provided to tell the audio status.

■ Playall function (OKY) plays all up to 64 defined sentences one by one by single trigger.

■ Playnext (sequential) function (OKY) : one trigger plays next sentence of up to 64 defined sentences circularly.

■ Random-play function (OKY) : one trigger plays one of 64 defined sentences randomly.

■ Continue sequence(PLAYNEXT):The first OKY trigger after any addressing will keep current sequence continuously.

■ Home sequence(PLAYNEXT):The first OKY trigger after any addressing will return the sequence to the first sentence.

■ Automatically ramp up & ramp down.

■ Sound Sentence & quality could be emulated on 9009 board.
