Product Introduction

NY8B062E is an EPROM based 8-bit MCU tailored for ADC based applications like home appliances or meter equipment. NY8B062E adopts advanced CMOS technology to provide customers remarkable solution with low cost, high performance. RISC architecture is applied to NY8B062E 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, NY8B062E is very suitable for those applications that are sophisticated but compact program size is required.

NY8B062E 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 NY8B062E 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, NY8B062E has built-in infrared (IR) carrier generator with selectable IR carrier frequency and polarity for applications which demand remote control feature.

NY8B062E 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, NY8B062E 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.
