Switching from PIC16F88 to PIC16F1828..?

Hello All; I am months deep in a project using a PIC16F88. I chose thie PIC due to its 6x6mm QFN package. However, I just found out the 6x6mm is sligthly too big for our package so I must choose a smaller PIC. I see the PIC16F1828 is available in a 4x4mm QFN package. I also like some of its other features as well...

My concern is I am tight on time and I want to make this transition go as smoothly as possible. I am an RF engineer and only works with PICs as a side hobby and only have less than 2 years of programming experience. Would anyone out there NOT recommend transitioning from a PIC16F88 to a 16F1818 for any reason? Is anyone fimiliar with?

Thanks in Advance

Looks like a nice part, shouldn't be that difficult to transition.

Less GPIO pins, but seems to be unavailable for a few months yet from ppl like Newark. Are samples available or simulators?

Hi Guys; Thanks for your responses. Yeah the IO pin count is less. I only am using 2 analog inputs, and 2 digital outputs. Utilizing the ADC (and with the PIC16F1828, the DAC as well, and possibly the capacitive sensing module). Microchip says they have them in stock...but I should check again. That lead time from Newark would put my project at a standstill!

Any other recommendations for other chips just in case?

Thanks again
Steve

Check the errata for this device as it has some issues with the ADC

This also affects the ADC on the 16F1826/7 and it's still there in Rev A4 silicon if I recall
