8-bit MCU chipset microcontroller I O Type

1.EPROM based 8-bit MCU tailored for I/O based applications like like remote controllers, fan/light
controller, game controllers, toy and various controllers. It adopts advanced CMOS technology to provide
customers remarkable solution with low cost and high performance benefits.

2.Provides 1 set of timer which can be used as regular timer based on system oscillation or event
counter with external trigger clock.

3.Adopts advanced CMOS technology to provide customers remarkable solution with low cost, high performance and high noise immunity benefits.

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

5.Provides kinds of operation modes to save power consumption and lengthen battery operation life.
