General Description

NY8BM72E is an MTP based 8-bit MCU tailored for ultrasonic atomizer applications. It also designed for ADC based  applications like home appliances or meter equipment. NY8BM72E adopts advanced CMOS technology to provide  customers remarkable solution with low cost, high performance and high noise immunity benefits. The feature of  re-programmable of MTP memory makes product development more flexible and efficient. RISC architecture is  applied to NY8BM72A and it provides 53 instructions. All instructions are executed in single instruction cycle except  program branch and skip instructions which will take two instruction cycles. Therefore, NY8BM72A is very suitable  for those applications that are sophisticated but compact program size is required.

NY8BM72E provide on-chip debug (OCD) facilities as a low cost alternative to ICE. With OCD and a minimum of  extra hardware, NY8BM72E can do ICE tasks such as free running, single stepping, break point setting and internal  ram/register accessing.

NY8BM72E provides 12+1 channel high-precision 12-bit analog-to-digital converter (ADC), and high-precision Low  Dropout Regulator and analog voltage comparator. They are suitable for any analog interface detection and  measurement applications.

The NY8BM72E built-in high speed oscillator can be optioned for different center frequency. users can adjust this  frequency in the program in a very small frequency step. With this feature ensures that NY8BM72E will find excellent  use in different ultrasonic nebulizer applications.

As NY8BM72E address I/O type applications, it can provide 18 I/O pins for applications which require abundant input  and output functionality. Moreover, each I/O pin may have additional features, like Pull-High/Pull-Low resistor and  open-drain output type through programming. Moreover, NY8BM72E has built-in large infrared (IR) carrier generator  (340mA@3V) with selectable IR carrier frequency and polarity for applications which demand remote control  feature.

NY8BM72E also provides 4 sets of timers which can be used as regular timer based on system oscillation or event  counter with external trigger clock. Moreover, NY8BM72A provides 3 sets of 10-bit resolution Pulse Width  Modulation (PWM) output and 3 sets of buzzer output in order to drive motor/LED and buzzer.

NY8BM72E employs dual-clock oscillation mechanism, either high oscillation or low oscillation can be derived from  internal resistor/capacitor oscillator or external crystal oscillator. Moreover, based on dual-clock mechanism,  NY8BM72E provides kinds of operation mode like Normal mode, Slow mode, Standby mode and Halt mode in order  to save power consumption and lengthen battery operation life. Moreover, it is possible to use internal  high-frequency oscillator as CPU operating clock source and external 32KHz crystal oscillator as timer clock input,  so as to accurate count real time and maintain CPU working power.

While NY8BM72E operates in Standby mode and Halt mode, kinds of event will issue interrupt requests and can  wake-up NY8BM72E to enter Normal mode and Slow mode in order to process urgent events.

NY8BM72E can be configured as NY8B072A, NY8B062A and NY8B062D compatible functions. As a result, these  body also share the benefit of NY8BM72E OCD.
