hi!

i would like to know if there is any PIC that is BIG or rather say that has three ports just like 16F877 but at a very cheaper price.

i have a lot of inputs that i cannot afford using port expanders since the outputs are also too many than the I/O pins for small PICs

urgent request!

Presumably you are wanting these for production purposes?, usually the cheaper OTP PIC's are used for that. If you have a look at https://asp.microchip.com/wwwParamChart/chart.aspx?branchID=1002&mid=&gdir=1010 it lists all the 16 series PIC's with prices - the 16F871 looks to be the cheapest PIC with 33 I/O pins, less than the OTP chips.
