General Description

NY8AE51F is a MTP/EEPROM based 8-bit MCU tailored for I/O based applications like remote controllers, fan/light  controller, game controllers, toy and various controllers. The MTP offers the advantage of convenient and effective  way of developing user program. The EEPROM, unlike SRAM, features data retention after IC is powered off.  NY8AE51F adopts advanced CMOS technology to provide customers remarkable solution with low cost and high  performance benefits. RISC architecture is applied to NY8AE51F 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, NY8AE51F is very suitable for those applications that are sophisticated but compact program size  is required.

As NY8AE51F address I/O type applications, it can provide 6 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, NY8AE51F has built-in infrared (IR) carrier generator with  selectable IR carrier frequency and polarity for applications which demand remote control feature.

NY8AE51F also provides 2 sets of timers which can be used as regular timer based on system oscillation or event  counter with external trigger clock. Moreover, NY8AE51F provides 3 set of 10-bit resolution Pulse Width Modulation  (PWM1/2/3) output and 1 set buzzer output in order to drive motor/LED and buzzer.

NY8AE51F employs dual-clock oscillation mechanism, both high oscillation or low oscillation can be derived from  internal resistor/capacitor oscillator. Moreover, based on dual-clock mechanism, NY8AE51F 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.

While NY8AE51F operates in Standby mode and Halt mode, kinds of event will issue interrupt requests and can  wake-up NY8AE51F to enter Normal mode and Slow mode in order to process urgent events.
