NY7 Series

Feature:

• Wide operating voltage range: 2.0V to 5.5V.
• Slow mode to operate at low power consumption. (+/-3% accuracy)
• Halt mode to save power, less than 1uA@3V standby current.
• Built-in internal Ring oscillation is accurate with +/- 0.5% frequency deviation.
• Each Bi-direction I/O pin can be optioned as different input and output function.
• Up to 24 flexible Bi-direction I/Os. Direction of each I/O is independently controlled by individual register bit.
• The selection of IR carrier frequency and data high/low IR output is supported.
• Maximum of 8 channels can be played simultaneously, each channel can be arbitrarily assigned as speech or MIDI channel.
• Patented noise filtering algorithm with 128KHz over sampling to enhance signal-to-noise ratio and provide excellent sound quality without ROM size increase.
• 16-step digital volume control for synthetic speech/melody.
• Built-in hardware automatic Tone-Calibration of near-zero frequency deviation for precise tone frequency.
• High quality 13-bit DAC, or 13-bit push-pull amplifier audio output with 4-level mask-option analog volume of 100%, 83%, 66% and 50%. (Push-Pull output power Pout=1.3W@VDD=5V, THD+N=10%, F=1kHz, RL=4Ω.)
