NY8A051F 8-bit MCU chipset microcontroller

1.EPROM based 8-bit MCU tailored for I/O based applications like remote controllers, fan/light
controller, game controllers, toy and various controllers. N

2.Provides 6 I/O pins for applications which require abundant input and output functionality
has built-in infrared (IR) carrier generator withselectable IR carrier frequency and polarity for applications which demand remote control feature.

3.Provides 2 sets of timers which can be used as regular timer based on system oscillation or event
counter with external trigger clock, and 1 set of 8-bit resolution Pulse Width Modulation
(PWM) output and buzzer output in order to drive motor/LED and buzzer

4.Employs dual-clock oscillation mechanism, both high oscillation or low oscillation can be derived from
internal resistor/capacitor oscillator.

5.Provides kinds ofoperation mode like Normal mode, Slow mode, Standby mode and Halt mode in order to save power consumption
and lengthen battery operation life.
