Functional Description
The HT815D0 is a mask ROM type voice synthe-
sizer with 11.2-second voice capacity. A group of
pre-recorded voice sections is played upon receipt
of key trigger input signals. Two FLAG signals
are output while playing voices.
The 11.2-second voice capacity can be divided
into sections of arbitrary length. Notice that the
silence length and end-pulse width are not in-
cluded in the memory.
By using Holtek s programming tools, the con-
tents and arrangement of sections, key features
and FLAG output are all programmable before
device fabrication.
The IC provides 12 key inputs (KEY1~KEY12).
Of the 12 keys, KEY1 can be optioned as a di-
rect, sequential or random trigger key. KEY12
can be selected as a stop or direct key. The re-
maining 10 keys (KEY2~KEY11), are used as
direct keys exclusively.

System oscillator
The HT815D0 has a built-in RC oscillator which
requires only one external resistor for normal ap-
plications. The oscillator frequency is typically
96kHz for an external resistor of 530k . The re-
quired oscillator frequency may vary with differ-
ent sampling rates in the process of voice
programming. As a result, the value of the oscilla-
tor resistor may be different for different items.
