Multi Channel Speech/Melody IC

NY2 Series

NY2 Series

NY2 Series

1-ch Speech or Dual-Tone Melody Synthesizer

The NY2 series is a single-chip dual-tone melody or 1-ch voice synthesizing CMOS IC. It has one input and five I/O pins. Through the accurate internal oscillation of +/- 1% tolerance and one built-in PWM output, thus any external component is not required. Using the same melody and speech algorithm, customer’s melody and speech data can be written into EPROM by different code data. The interactive software developing tools of “Q-Tone”, “Q-Melody” & “Quick-IO” are user-friendly and quick for programming, then users can write BIN code into OTP very fast by “Q-Writer“ software cooperating with “OTP_Writer“ hardware.

Feature:

  • Wide operating voltage: 1.8V ~ 5.5V.
  • The total melody and voice duration can be partitioned up to maximum 128 Voice/Melody Sections.
  • Dual-Tone melody and voice can’t be played simultaneously. Meanwhile either melody or voice can be played only. User can fill out different Voice Section and Melody Section into Steps of one Sentence to achieve voice playing among melody notes.
  • here are 25 kinds of tempo. The synthesized beat imitates the original envelope, and the synthesizing beats can assign the same or different pitch and output option.
  • All output pins support large-current output and can directly drive high brightness LED. (Iol=20mA@VDD=3V)
  • All output pins can be set as Constant Sink Current (CSC) output individually for current limit at 4.5V.
  • There are 2 kinds of PWM output, normal and large. It can directly drive 8, 16, 32, 64Ω speaker or piezo-buzzer.
  • Low-Voltage-Reset (LVR) option. When voltage is lower than 1.8V, IC will reset by itself. (Mask Option)
