Today we bring you an overview of NY8A054E microcontroller and its features and applications. NY8A054E microcontroller is an 8-bit microcontroller with EPROM as memory, which uses CMOS process and its core is built on RISC compact instruction set architecture which can be easily programmed and controlled with 55 instructions in total. Except for a few instructions that require two instruction clocks, most instructions can be completed with one instruction clock, allowing users to easily complete different applications with program control.
I. NY8A054E Microcontroller Features
(1) There are 12 flexible bi-directional I/O pins, each I/O pin has a separate register to control as input or output pin;
(2) Built-in infrared carrier transmitter port with selectable frequency;
(3) There are two sets of timers, which can be used as a general timekeeping application with the system clock or triggered from an external signal to count;
(4) Provide a set of 8-bit pwm output or buzzer output, which can be used to drive motors, buzzers, etc;
(5) using a dual clock mechanism, high-speed oscillation clock or low-speed oscillation clock by the content of RC oscillation or external crystal input;
Second, the NY8A054E microcontroller function features
12 I/O pins can be individually controlled input and output directions;
1Kx14-bit program memory space; 64 bytes of general data register space;
Built-in power-on reset circuit (POR). Built-in low voltage reset function (LVR).
One 8-bit down timer (Timer1) can be selected for automatic reload or continuous down timer. An 8-bit pulse width modulation output (PWM1).
A buzzer output (BZ1). 38/57KHz infrared carrier (IR) frequency can be selected, and the polarity of the carrier can also be selected by register.
Built-in Watchdog Timing (WDT), which can be controlled by Configuration Word.
Four operating modes to adjust current consumption according to system requirements: Normal mode, Slow mode, Standby mode and Halt mode
Five kinds of hardware interrupts: Timer0 overflow interrupt; Timer1 underflow interrupt; WDT interrupt; PB input state change interrupt; external interrupt input.
Three, NY8A054E microcontroller applications
As mentioned above, NY8A054E microcontroller is an 8-bit microcontroller with EPROM as memory, which is suitable for applications with multiple I/O port products, such as fans, lighting control, remote control and other small home appliances commonly used in life.
