Product Overview

NY8A051D is an 8-bit microcontroller with EPROM as a memory, designed for multi-IO applications such as remote controls, fan/light controls or toy peripherals. CMOS process and provide customers with low cost, high performance and other advantages. The NY8A051D core is built on a RISC reduced instruction set architecture that can be easily programmed and controlled, with a total of 55 instructions. Except FOR a few instructions that REQUIRE TWO instruction CLOCKS, MOST INSTRUCTIONS can be completed by ONE INSTRUCTION clock, allowing users to easily programmatically control different applications. Therefore, it is very suitable for a variety of low and medium memory capacity but complex applications.

In terms of resources for I/O, NY8A051D has six elastic bidirectional I/O feet, each of which has a separate register control for input or output feet. And each I/O pin has the associated register to achieve pull up or pull down resistance or Open-Drain output. In addition, for infrared remote control products, NY8A051D is built with a selectable frequency infrared carrier transmitter.

The NY8A051D has two sets of timers, which can be used as a general timing application by the system clock or triggered by external signals. In addition, NY8A051D provides a set of 8-bit PWM outputs or buzzer outputs that can be used to drive motors, leds, or buzzers, etc.

NY8A051D uses a dual-clock mechanism, in which both the high-speed oscillation clock and the low-speed oscillation clock are input by the internal RC oscillation. Under the dual-clock mechanism, NY8A051D can select multiple operating modes, such as Normal, Slow, Standby and Haltmode, which can save power consumption and prolong battery life.

In power-saving modes, such as Standby mode and Halt mode, multiple interrupt sources can be triggered to wake the NY8A051D into Normal mode or Slow mode to handle emergencies.
