EM20035
3 SEC. VOICE SYNTHESIZER IC.
4.12.1996
The voice section is combined by one voice part and the corresponding pause part, that is,
The duration of pause is programmable which is 0 sec < Pause N < Voice N, 1
≤
N
≤
6
The section combination of voice group is programmable. The maximum number of section combination
is 30 and 14 for group 1 and group 2 respectively. If the number of section combination of group 1 is greater
than 16, then trigger 2 is not available. The total section number can not exceed 30.
For examples:
Group 1 : Sec 1, Sec 2, Sec 6, Sec 4, Sec 3, Sec 1, Sec 2
Group 2 : sec 2, Sec 4, Sec 1
B). Stop Pulse
At the end of each triggered voice group playing, STP pin can be defined to issue a positive pulse or not
by mask option with pulse width 40ms. The STP signal is provided to trigger external device.
C). Operation Functions
EM20035 provides 3 operation modes. They are One-shot, Level and Coincidence. The operation mode
of each trigger pin (TR1,TR2) can be selected independently with mask option. To prevent mistaken action
due to bounce of trigger switch, any bounce shorter than 20 ms will be ignored by the debounce circuit of
EM20035.
Mode1 : (One-shot, with retrigger)
EM20035 play triggered group with preseted combination of sections.
