    NY8A056A is an 8-bit microcontroller with EPROM as memory, designed for I/O applications such as home appliances or measurement. The CMOS process provides customers with significant advantages such as low cost, high performance, and high resistance to electromagnetic interference. The NY8A056A core is built on the RISC Reduced instruction set architecture for easy editing and control, 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.

    In terms of I/O resources, the NY8A056A has 16 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, NY8A056A built in a selectable frequency of high-current output infrared carrier transmitter, the current can reach 340mA at 3V power supply.

    The NY8A056A has three sets of timers that can be counted at the system frequency for general timing applications or triggered from an external signal. In addition, the NY8A056A provides two sets of 8-bit resolution PWM outputs or buzzer outputs that can be used to drive motors, leds, or buzzers.

    NY8A056A uses a dual clock mechanism, high speed oscillation or low speed oscillation can be selected respectively internal RC oscillation or external Crystal input. Under the dual-clock mechanism, the NY8A056A can select multiple 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 the power saving mode, such as Standby mode and sleep mode, various events can trigger the NY8A056A to wake up to Normal mode or Slow mode to deal with emergencies.
