General Description
The EasyVoiceTM is a single-chip voice synthesizer LSI . The chip when triggered drives a speaker directly or through an external transistor with a PWM output. Negligible current is consumed in the standby state.

FEATUREs
• Operating voltage: 2.4V~5V
• Directly drives an external transistor
• PWM function directly driver speaker
• Low standby current (1A typ. for VDD=3V)
• Minimal external components
• 240 notes table ROM for key functions
• Programmable silence length and end-pulse width (minimal end-pulse width is 1.3ms at 8kHz sampling rate)
• Controllable volume
• FLAG1 options
    - End-pulse output
    - 3Hz, 3HzB flash
    - 6Hz, 6HzB flash
    - Busy output
    - OFF
• FLAG2 options
    - 3Hz flash
    - 6Hz flash
    - Busy output
    - OFF
• 6 keys (Directed)
• 8 keys (Matrix key)
• Key options
    - Sequential/Directed
    - Repeat (KEY2~KEY6)
    - STOP key (KEY6)
    - Key debounce time: 1.2ms, 22ms, 45ms (based on a 8kHz sampling rate)
    - One shot/Normal
    - Pull-high resistance: 0, 50kΩ, 100kΩ, 200kΩ
