NY8B062E Overview:
The NY8B062E is an 8-bit microcontroller with EPROM as memory, designed for I/O applications such as home appliances or measurement. CMOS process and at the same time to provide customers with low cost, high performance, and high cost performance and other significant advantages. The NY8B062E 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.
NY8B062E has built-in high precision eleven plus one channel twelve-bit analog-to-digital converter, and high precision voltage comparator, which is sufficient to cope with the detection and measurement of various analog interfaces.
In terms of I/O resources, the NY8B062E has 14 elastic bidirectional I/O pins, each with a separate register controlled 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, NY8B062E has built-in infrared carrier transmitter with selectable frequency.
The NY8B062E 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 NY8B062E offers three sets of 10-bit resolution PWM outputs and three sets of buzzer outputs that can be used to drive motors, leds, or buzzers.
The NY8B062E uses a dual-clock mechanism, and the high or low speed oscillations can be selected from internal RC oscillation or external Crystal input, respectively. Under the dual-clock mechanism, the NY8B062E can choose a variety of operating 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 various events that can trigger the interrupted wake-up of the NY8B062E into Normal mode or Slow mode to deal with emergencies.
