Functional characteristics
 
  • OTP storage format, production cycle is fast, only the fastest one day, place an order is no minimum limit
  • Flexible multi key mode of operation and the level of output options (edge trigger button, triggering level, random keys, the keys sequence to play )
  • Simple two lines MCU serial control mode. The user of master MCU can control the touch of arbitrarily segments of speech to play or to stop
  • The voice could play 40 seconds,65 seconds, or 80 seconds
  • Support 4 trigger button
  • Built in a group of PWM, this output direct push 0.5W horn
  • Have a good sound, stable performance and high quality and inexpensive
  • The peripheral circuit is simple, only needs a coupling capacitor
  • Working voltage range: 1.8V ~ 4.5V (5V power VDD series should connected capacitor step-down if needed)
  • Quiescent current: 2uA
  • DIP8, SOP8 and COB three kinds of packages are available. It’s easy and flexible to use.
