VOICE ROM
Features
Single power can operate at 2.4 V through 6V.
Current output could drive 8 ohm speaker with a
transistor, Vout could drive buzzer directly.
The voice content is stored up to 15 seconds and
can be separated to 64 sections.
Duration of each section can be different.
Mute is available for each section up to 48
seconds totally.
A Forever Play function is available.
Four addressing interface modes are provided for
versatile applications: CPU, Stand alone, Ring
Trigger and Table Trigger.
Stand alone mode:
8 sections can be accessed by 8 trigger input
pins individually.
Table trigger mode:
a. A phrase is accessed by TG0, low active.
b. This phrase is composed of 16 elements
contiguously as the table content.
c. These 16 elements are chosen from 8 sections.
d. Section is located and numbered by 0 through 7.
Ring trigger mode:
a. A section-by-section phrase is accessed by TG0,
low active.
b. This phrase is composed of 16 element (section)s
contiguously as the table content.
c. Each single trigger plays next one element (section)
following above sequence.
d. These 16 elements are chosen from 8 sections.
e. Section is located and numbered by 0 through 7.
CPU addressing mode:
a. 64 sections can be accessed by 6 address bits
with enable strobe trigger.
b. Section is located and numbered by 0 through 63.
c. The address bit is high true.
Mask option for either retriggerable output or not.
Mask option for either Level or Edge trigger type.
For all four modes, retrigger action restarts playing
from the beginning.
One BUSY output signal is available.
Automatic power down function(selected by external
input, pwr).

Block Diagram
The MSS1506 is a single-chip CMOS LSI ROM that can memorize voice up to 15 seconds using MOSEL
qualified coding method (MPCM).
Four addressing interfaces are provided: CPU mode, Stand Alone mode, Ring Trigger mode and Table Trigger
mode for versatile applications. The voice content can be stored separatly into 64 or 8 or 16 sections or 1
phrase with arbitary length. With minimum external components, this chip can be applied to various
application. Customer voice is edited and programmed into ROM by changing one mask during fabrication.

Note: 1. AUDIO means cout, vout1, vout2.
2. TG0 ~ TG5, E1/TG6, E2/TG7 are all internal pull high.
3. For standalone mode, TG0 ~ TG7 are used as section trigger input (active low).
4. Every retrigger action will reload address and play the audio output from the beginning.
5. In CPU mode to avoid unwanted noise caused by abrupt change between different sections
of messages, it is recommended to program PWR pin to high (V ) during voice processing.
