Hello.

I'm doing another instructable, this time, LED clock. I'm using PIC16F886, because code is not well optimized yet, so it takes about 6K of memory. I will slim it down, but I'm afraid it won't fit into most common 16F628A. Which is another popular chip, like 628A, but with more memory, 4K at least? Preferably, with internal oscillator, to reduce external part count.
