Product Introduction

NY8B062F is an EPROM based 8-bit MCU tailored for ADC based applications like home appliances or meter equipment. NY8B062F adopts advanced CMOS technology to provide customers remarkable solution with low cost, high performance. RISC architecture is applied to NY8B062F and it provides 55 instructions. All instructions are executed in single instruction cycle except program branch and skip instructions which will take two instruction cycles. Therefore, NY8B062F is very suitable for those applications that are sophisticated but compact program size is required.

NY8B062F provides 11+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.

As NY8B062F address I/O type applications, it can provide 14 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, NY8B062F has built-in infrared (IR) carrier generator with selectable IR carrier frequency and polarity for applications which demand remote control feature.

NY8B062F 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, NY8B062F provides 4 sets of 10-bit resolution Pulse Width Modulation (PWM) output and 3 sets of buzzer output in order to drive motor/LED and buzzer.

NY8B062F 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, NY8B062F 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.
