Hi,
I am making a small PCB and I will need to produce a small batch (about 20 pieces). I will hanve to hand-solder everything, so I'm looking for something with a very low part count. I will need USB (at least for firmware updates).
From the parts that are available at local store, the PIC16F1455 is pretty close to what I needed
-Can be programmed with the pickit3 I already own
-I can do USB with only 1 chip and 3 caps (+1 resistor for first flash, but this one is on my programming cable)
But it has some drawbacks :
-Few flash available (USB stacks takes more than half of it)
-Annoying page switching (low en PIC architecture
)
-No Arduino environnement support (I don't use / like arduino, but other people who will maintain the code would appreciate it)
Is there any higher-end PIC or AVR or Cortex that can do USB with almost-zero external component, and is available with a 0.65mm or larger pitch, and is not too expensive ? (I have AVR and Pic programmer but no Cortex, so if cortex comes with a cheap programmer or USB Bootloader pre-flashed, it's nice)
Thank you,
John.
