6/15/2023 0 Comments Pic16f628a Serial ProgrammerThe chip has 4MHz and 37kHz internal oscillators. I/P I indicates temperature range: I = -40☌ to 85☌ (normally 0☌ to 70☌)Ī chip with -20 means the chip is capable of operating at 20MHz via an external crystal and will execute 5 instructions per second when the crystal is 20MHz. PIC16F628A Internal 4MHz or 48kHz operation, plus low voltage programming, low speed clock mode, programmable BOR, on-chip voltage reference. PIC16F628 - Internal 4MHz or 37kHz operation, 18pin PDIP package (see photo below). We use the type number: PIC16F628 to describe this microcontroller, but there are a number of part-numbers: The 4MHz oscillator is divided by 4 to get 1uS for each instruction. The PIC16F628 has 2k of program space for your program (2048 lines of code), operates at 4MHz and is cheaper than the PIC16F84A. Obviously you shouldn’t have a soldering iron so hot that it fumes the solder. (For 1 to 5 “drive-lines” use PIC12F629.) The PIC16F628 is the starting point for PIC projects that require 6 to 15 “drive-lines.” PIC16F628 PDF Data Sheet Instruction Set for PIC16F628 PIC16F628A.INC Library of Routines A-E E-P P-Z Blank_F628.asm or Blank_F628.txt Notepad++ or VS Code
