The NY8A053E is an 8-bit microcontroller with EPROM as memory, designed for multi-IO applications such as remote controls, fan/light controls, or video instrument peripherals. CMOS process and at the same time to provide customers with low cost, high performance and other significant advantages. The NY8A053E 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 NY8A053E has 12 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, NY8A053E has built-in infrared carrier transmitter with selectable frequency.
    The NY8A053E has two sets of timers that can be counted at the system frequency for general timing applications or triggered from an external signal. In addition, the NY8A053E offers four sets of 10-bit resolution PWM outputs or buzzer outputs that can be used to drive motors, leds, or buzzers.
    NY8A053E uses a dual clock mechanism, high speed oscillation or low speed oscillation can be selected respectively internal RC oscillation or external Crystal input. In the dual-clock mode, the NY8A053E 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 NY8A053E to wake up in Normal or Slow mode to deal with emergencies.
