Multi Channel Speech/Melody IC

NY6 Series

NY6 Series

NY6 Series

4-bit MCU with 6-ch Speech/MIDI

As NY6 is specially designed for MIDI synthesis application, it provides Attack-Decay-Sustain-Release method (ADSR) with 256-level envelope for Patch (instrument) synthesis. NY6C can precisely synthesize any tone frequency of MIDI with +/- 0.5% accurate internal oscillation and automatic Tone-Calibration. Therefore NY6 melody quality is very close to real instrument. Moreover, NY6C is equipped with new Nyquest’s developed high-quality noise filtering algorithm of 250KHz over-sampling, which can remove noise in order to improve speech and melody quality greatly. Up to 16-level digital volume can be applied to final synthetic speech or melody that is tailored for applications of volume adjustment. NY6 provides two kinds of audio outputs with fine resolution, one is 12-bit current-type D/A converter (DAC) and the other is 12-bit Pulse-Width-Modulation (PWM). The RISC MCU architecture is, various applications can be easily implemented There are 75 instructions, and most of them are executed in a single cycle. Besides normal operation mode, NY6 also provides Halt mode (or Sleep mode) and Slow mode to minimize power dissipation.

Feature:

  • Wide operating voltage range: 2.0V to 5.5V.
  • 4-bit RISC type micro-controller with 75 instructions.
  • Slow mode to operate with low power consumption (+/- 3.0% accuracy).
  • HALT mode to save power, less than 1uA@3V standby current.
  • Built-in RC oscillation is accurate with +/- 0.5% frequency deviation.
  • Low voltage reset (LVR=1.9V), watch-dog reset and I/O port reset are all supported to protect the system.
  • Low Voltage Detector (LVD) is built-in for monitoring the status of power and protect malfunction if unstable power is given.
  • LDO regulator is supported for the power supply of SPI flash.
  • Hardware SPI for external SPI devices data access. Dual power system operation supported (ex: NY6C @ 5V, SPI @ 3V).
  • Shared pins to provide IR carrier, comparator, SPI interface and external reset feature. (Mask option)
  • Maximum of 6 channels can be played simultaneously, and each channel can be arbitrarily assigned as speech or MIDI channel.
  • Patented noise filtering algorithm with 250KHz over sampling to enhance signal-to-noise ratio and provide excellent sound quality without ROM size increase.
  • PWM driver can be normal PWM or Ultra PWM.
