The NY8L050A is a high-performance 8-bit 65C02 microcontroller with additional LCD driver and sound playback capabilities, three sets of 8-bit timer/counter, and 32 I/ OS. In addition to the console function, the LCD driver unit also has built-in key detection function.
    The sound playback function has 3 channels, 1 channel can play voice, the other two channels for dual-channel music, all channels can be played simultaneously. When playing, it uses high sound quality ADPCM synthesis algorithm, the playback sampling rate can be to 16KHz@4MHz, and supports volume adjustment, which can constitute high-quality sound playback. NY8L050A provides two high-precision audio output modes, one is 10-bit DAC output, and the other is 9-bit PWM output. The NY8L050A provides 4-channel, 8-bit precision ADC functionality for diagnostic and measurement applications of analog signals.
    MCU for CISC architecture is easy to program and control and plan for a variety of applications. In addition, it provides a variety of working modes Slow mode, Standby mode and Halt mode(Sleep Mode) to effectively reduce power consumption.
