PIC16F628A Microcontroller

• PIC16F628A is a CMOS FLASH-based mid-range 8-bit microcontroller that comes with an 18-Pin package, out of which, 16 pins can be used as I/O pins. This microcontroller has 4 Mhz of internal oscillator with 128 bytes of EEPROM data memory, packed with a single PWM and a USART module with 2 comparators. Low voltage programming is supported by this microcontroller unit.
• PIC16F628A microcontroller also has two 8-bit and one 16-bit timer suitable for timing-related mid-range applications where different timers are required.
• Components associated with PIC�PICkit3, Pic development board, Crystal oscillators, capacitors, 12V Adapter, 7805 Voltage Regulator.
• MPLAB C18 Compiler is the standard compiler used for PIC microcontrollers. You can get this compiler online from the Microchip Official Site. The code is written in PIC Compiler that compiles the code and generates a hex file that is uploaded on the PIC Microcontroller.
