EM20035
3 SEC. VOICE SYNTHESIZER IC.
4.12.1996
GENERAL DESCRIPTION
EM20035 is a single chip voice synthesizer IC with built-in on-chip ROM. This chip may synthesize speech
phrase, imitate animal voice or produce special sound effect. The voice data that has been edited by PCM
tooling system is programmed into masked ROM during IC fabrication. The maximum voice duration of
EM20035 is 3-4 seconds (depends on the characteristics of synthesized vioce) and can be partitioned into
maximum 6 voice sections with arbitary length.
FEATURES
Single power supply 2.4 V - 5.1 V.
3 seconds voice capacity.
Voice duration is separated into 6 sections with arbitrary length.
Provides 2 trigger pins to two voice groups.
Provides each trigger pin with four operation modes independently, they are One-shot with retrigger, One-
shot without retrigger, Level and Coincidence (with mask options).
Provides switch and CdS trigger input interface.
Provides stop pulse output.
Pause duration between voice sections is programmable.
Power on trigger is available. (excluded for One-shot mode).
Built in PRM ckt to drive piezo buzzer or myler speaker directly.
14 pin DIP package form \ Bare chip form.
