PIC Question - William Oliver - Jun 3 16:01:08 2006

Hello, All,

I have a question about some PIC Microcontrolers, Can someone tell me the difference between a 16F84 and a 16CR84, They are both listed on the same data Sheet.

Best regards.

16F84 = Flash re-programmable
16CR84 = One time programmable

Sure, the CR has ROM memory; the factory programs it for you. The F
has flash memory and you can program/reprogram as you see fit.

See section 2.4 of the PIC16F8x datasheet.
