NY8B062A

NY8B062A is an 8-bit microcontroller with EPROM as memory, except for I/O applications such as home appliances or measurement.
NY8B062A built-in high precision eleven plus one channel twelve-bit analog to digital converter, and high precision voltage comparator, enough to cope with a variety of analog interface detection and measurement.
NY8B062A built-in high frequency oscillator can flexibly select the output frequency range to suit a variety of nebulizer components, and can also be programmed to fine-tune the output frequency, fine enough to cope with the nebulizer component deviation.
The NY8B062A has 14 elastic bidirectional I/O pins, each with a separate register control as an input or output pin.
The NY8B062A has four sets of timers, which can be counted on the system frequency as a general timing application or triggered from an external signal.
The NY8B062A uses a dual clock mechanism, and the high speed oscillation or low speed oscillation can be selected respectively from the internal RC oscillation or the external Crystal input.
    NY8B062A Overview:
        NY8B062A is an 8-bit microcontroller with EPROM as memory, except for I/O applications such as home appliances or measurement. More optimized for atomizer products. The CMOS process provides customers with significant advantages such as low cost, high performance, and high resistance to electromagnetic interference. The NY8B062A core is built on the RISC Reduced instruction set architecture and can be easily edited and controlled, with a total of 55 instructions. Except for a few instructions that require 2 sequences, most instructions can be completed in 1 sequence, allowing users to easily complete different applications with program control. Therefore, it is ideal for a variety of low and medium memory capacity but complex applications.
        NY8B062A built-in high precision eleven plus one channel twelve-bit analog to digital converter, and high precision voltage comparator, enough to cope with a variety of analog interface detection and measurement.
        NY8B062A built-in high frequency oscillator can flexibly select the output frequency range to suit a variety of nebulizer components, and can also be programmed to fine-tune the output frequency, fine enough to cope with the nebulizer component deviation.
    In terms of I/O resources, the NY8B062A has 14 elastic bidirectional I/O pins, each with a separate register control as an input or output pin. And each I/O pin has additional program-controlled functions such as pull or pull down resistance or Open-Drain output. In addition, for infrared remote control products, NY8B062A has built-in infrared carrier transmitter with selectable frequency.
        The NY8B062A has four sets of timers, which can be counted on the system frequency as a general timing application or triggered from an external signal. In addition, the NY8B062A offers three sets of 10-bit resolution PWM outputs, and three sets of buzzer outputs can be used to drive motors, leds, or buzzers, among others.
        The NY8B062A uses a dual clock mechanism, and the high speed oscillation or low speed oscillation can be selected respectively from the internal RC oscillation or the external Crystal input. Under the dual-clock mechanism, the NY8B062A can choose a variety of working modes such as Normal mode, Slow mode, Standby mode and sleep mode to save power consumption and extend battery life. And when the microcontroller uses the internal RC high-speed oscillation, the low-speed oscillation can be simultaneously timed using the external precise Crystal. It can maintain high-speed processing while accurately calculating the true time.
        In power-saving modes such as Standby mode and sleep mode, there are a variety of events that can trigger the interrupted wake-up of NY8B062A into Normal mode or Slow mode to deal with emergencies.
