The NY8BM72A is an 8-bit microcontroller with MTP 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. MTP is a more convenient and efficient development product for program memory. The NY8BM72A core is built on the RISC Reduced instruction set architecture for easy editing and control, with a total of 53 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.

    The NY8BM72A has a built-in debug emulator circuit that uses two pins and very little external hardware to achieve most of the functions of the online emulator, such as setting program execution conditions and interrupt conditions, on-chip single-step execution, and viewing and setting the contents of various registers. The execution effect of the simulation will be closer to the actual IC operation than the ordinary simulator.

    NY8BM72A built-in high precision 12+1 channel 12-bit analog-to-digital converter, and high precision voltage comparator, enough to cope with a variety of analog interface detection and measurement.

    The NY8BM72A 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 enough to cope with the nebulizer component deviation.

    In terms of I/O resources, the NY8BM72A has 18 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, the NY8BM72A has built-in infrared carrier transmitter with selectable frequency.

    The NY8BM72A has four sets of timers, which can be counted at the system frequency as a general timing application or triggered from an external signal. In addition, the NY8BM72A offers three sets of 10-bit resolution PWM outputs and three sets of buzzer outputs that can be used to drive a motor, LED, or buzzer.

    The NY8BM72A uses a dual-clock mechanism, and the high or low speed oscillations can be selected from the internal RC oscillation or the external Crystal input, respectively. Under the dual-clock mechanism, the NY8BM72A 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 various events that can trigger the interrupted wake-up of the NY8BM72A into Normal or Slow mode to deal with emergencies.

    The NY8BM72A can be initially configured to be compatible with NY8B072A, NY8B062A and NY8B062D. Therefore, in addition to using NY8_ICE, the three mothers can also use the NY8BM72A built-in debug simulation circuit to simulate the actual IC action.
