Electronic keyboard standard voice chip

The GYN1 series products are single-chip CMOS LED control driver synthesis ICs. There is no need to add an external oscillator resistor. Each 0utput can provide different current outputs and can be used with software current control to drive LEDs of different brightness. A constant current output can also be selected to protect the LED. The flash synthesis method can arbitrarily compose various flash modes. By changing the Code mask during the manufacturing process, different flash data can be written into the ROM. Users can develop quickly using the simple Q-Light tool software.

The GYN3(B) series products are single-chip CMOS speech synthesis 1C, providing customers with excellent sound quality. Depending on the series, there are 1 to 5 1/0 pins that use precise internal resistance to oscillate, so there is no need to add an external oscillation resistor. There is only one set of PWM outputs, so there is no need to add any additional parts. By changing the Code mask during the manufacturing process, different voice data can be written into the ROM. Users can develop quickly using easy-to-use Q-Speech and Quick-10 software tools.

The speech synthesis method of the GYN4 (B) series uses high-quality ADPCM algorithm, with a maximum sampling rate of up to CD quality 44.1kHz, and a built-in noise filter circuit to reduce background noise. Using the RISC reduced instruction set architecture, there are a total of 44 instructions. Except for a few instructions that require 2 timings, most instructions can be completed in 1 timing. It can be easily programmed to complete different applications. Using precise +/-1% internal resistance oscillation, no external oscillation resistor is needed. Provides standby mode (Halt mode) to significantly save power consumption

The GYN5 series of products is a multi-functional single-chip CMOS speech synthesis 4-bit microcontroller that provides 4-channel speech/Midi synthesis function. The speech synthesis method adopts the advanced high-quality ADPCM algorithm. The highest sampling rate can reach CD quality 44.1kHz, and the hardware There are 16 levels of volume control. There are two sound output methods to choose from, a PWM output and a DAC output. Using the RISC reduced instruction set architecture, there are a total of 48 instructions. Except for a few instructions that require 2 timings, most instructions can be completed in 1 timing, making it easy to complete different applications under program control. Using the precise +/-1% internal resistance oscillation, customers do not need to add an external oscillation resistor, but a 0SC pin is flexibly reserved for external oscillation resistor. When only using the internal resistance oscillation, this pin can be used as a general I/O 0 feet used. It provides a standby mode (Halt mode), which can significantly save power consumption; it also provides a slow mode (Slowmode), which can reduce power consumption.

GYN7 is specially designed for MIDI synthesis applications. Both voice and MIDI timbre synthesis can use the high-fidelity 6-bit ADPCM algorithm, plus precise +/-0.5% internal resistance oscillation and built-in hardware automatic tuning. Function, GYN7 can accurately synthesize MIDI notes, making the sound effects close to real musical instruments. GYN7 provides two audio output methods to choose from, 13-bit DAC output and 13-bit push-pull (Push-Pu11, PP) output. Therefore, GYN7 voice/music quality is the best of all options.
