PIC 16F627

The PIC 16F627 is a fairly good replacement device for the 16F84 as it has a lot of usable built in peripherals but it has the same amount of program memory as the 16F84 i.e. 1k. So if you are running out of memory space then I suggest you use a 16F628 as it has twice the program memory.

Note : You may be ok as the RAM is larger so the C compiler will have more room to manoeuver so try it out on the compiler first and simulate your program.

The 16F84 has 1 peripheral (Timer 0) whereas the PIC16F627 has:

  • Three timers.
  • USART.
  • CCP (for Pulse Width Modulation, capture and compare).
  • Analogue comparator.
  • 1k program memory - fairly bad.

(i.e. the same peripherals as the 16F628)

Another feature is that you can switch it from internal 4MHz to slow speed internal 37kHz on the fly so you can used it in power sensitive applications.

Its best feature is

  • 224 Bytes of RAM.

This is nearly four times as much as the 16F84 and, for high level language use, this makes it much easier to use as it is the resource the you run out of most quickly.

The 16F627 is only really missing an ADC and I2C capability but to use it effectively you are really going to have trouble with its limited program memory - the 16F628 or 16F88 are better choices.

Note : You may be ok as the RAM is larger so the C compiler will have more room to manoeuver so do try it out on the compiler first and simulate your program.

You could program I2C by soft coding in C (see this project) and you could use an external ADC but you will probably run out of program memory space.
