GENERAL DESCRIPTION
The MTS3103/6/9 is a single-chip synthesizing CMOS VLSI that can synthesize voice up to 3 seconds, 6 seconds and 9 seconds by Log_PCM algorithm.
Customers’speech data are edited and programmed into ROM by changing one mask during the device fabrication.

FEATURES
• Operating voltage: 2.4v ~ 6.0v
• Single word
• 1 trigger input PAD
• 1 Level option input
• 1 status output (Busy_high; Static_LED_fast;Static_LED_slow; Dynamic)
• Trigger mode selection: Edge/Level, Hold/Unhold, Retrigger/Irretrigger
• Debounce mode : Fast debounce: < 30us
• Slow debounce : ~10ms (S.R. = 6kHz)
• Play times: max. 8 (Total 8)
• PWM playing port; Drive speaker or buzzer directly
• Voice length: 3 seconds for MTS3103, 6 seconds for MTS3106 and 9 seconds for MTS3109 (S.R. = 6kHz) (Rom capacity = 18048*5 bit for MTS3103 / 36096*5 bit for MTS3106 / 54272*5 bit for MTS3109)
• Voice+Mute length : up to ~20 seconds. (S.R. = 6kHz)
• Voice algorithm : Log_PCM
• External resister for system frequency.
