Please log in for more thread options I'm sorry if this question is asked several times before. I want know the difference between C and F series microcontrollers? I'm sure microchip maybe having such a comparison sheet, but I can't find one :-(, is anybody having a pointer to it? TIA | ||||||||||||||||||||||||||||

Please log in for more thread options > "F" means EEPROM/Flash while "C" means EPROM.
> > You can also view detailed specifications of parts at > http://www.microchip.com under "Product DataSheets." I'm familiar with 16f series, where you have 35 instructions set. There are several other series also, like 12 and 18 how do they differ; I guess they have different set of instructions, is that right? Which mcu should I consider for my application, where I have two inputs and two outputs? Outputs will switch on/off at a delay of 10minutes depending upon the state for inputs. I think an 8pin mcu will make it, but I'm not sure which one? Thanks | ||||||||||||||||||||||||||||

-> -> You can also view detailed specifications of parts at -> http://www.microchip.com under "Product DataSheets." -I'm familiar with 16f series, where you have 35 instructions set. -There are several other series also, like 12 and 18 how do they -differ; The 12 series are smaller chips (8 pins). The 18F is a high range family with a lot more features and instructions. But it solves most of the annoying problems of the 16F family in terms of memory banking. - I guess they have different set of instructions, is that -right? Augmented instructions for the 18F. The 12F family is pretty much 16F style parts in a smaller package. - -Which mcu should I consider for my application, where I have two -inputs and two outputs? Anything will do for 2 digital inputs and output. If it's analog, you may have to limit your options. As a hobbyist I always suggest picking a single part in each package size and sticking to it loke glue. I also suggest picking the part with the most features so that you won't be limited. Given that here are some recommendations: 8 pin: 12F683 18 pin: 16F88 or 18F1320 28 pin: 16F876A or 18F2320 40 pin: 16F877A or 18F4320 Personally I find microchips nanowatt clock module, of which all of the above parts except for the 16F87[67]A has, invaluable. -Outputs will switch on/off at a delay of 10minutes depending upon the -state for inputs. - -I think an 8pin mcu will make it, but I'm not sure which one? 12F683 may be the ticket for this one. Note that microchip samples most every PIC in the lineup. BAJ | ||||||||||||||||||||||||||||

The C series us one-time programmable (OTP) memory. You should use the F series for program development. Dave :) | ||||||||||||||||||||||||||||
