Are there any mainstream 32 bit MCUs other than the MIPS based PIC32MX available in PDIP ? I'm especially interested in ARM architecture MCUs, but any 32 bit architectures are of interest; they don't need to have USB built in. When I was looking for the currently available MCUs with USB device built in, it was a major surprise to discover a 32 bit MIPS MCU range available in PDIP. I had a look to see if there were any ARM MCUs available in PDIP but without success. I know you can buy ARM MCUs mounted on a PDIP package, but I'm interested if the MCU itself is available in PDIP.

You can go into embedded/microcontrollers, filter by ARM core, then look at the available DIP packages. There aren't any. -- John Devereux

I didn't think of Digikey, but I did try other places, including manufacturer websites, and also came up empty. It was just seeing the PIC32MX available in PDIP (and not knowing about it until now) made me wonder if anyone else was also doing 32 bit PDIP MCUs and I just had not come across them yet.

Recently the others seem to be trying for this market too, perhaps realising that the hobbiests of today could be the product designers of tomorrow. But they are doing it with very low cost development boards (and free tools). Not as DIP packaged chips. -- John Devereux

Besides, a 40-pin DIP is pretty danged big already; imagine a 64- or 100-pin monster. Your best bet is probably to look for the device already mounted in a header board with breakout pins. See, for example, <http://www.sparkfun.com/products/8559> If you're more into roll your own, look for prototyping adapters that break-out the SMT processor's pins into accessible headers. Bellin makes a lot of these in various configurations http://www.beldynsys.com/ and there's the Schmartboard system http://www.schmartboard.com/ -- Rich Webb Norfolk, VA

NXP's LPC1114FN28/102 (Cortex-M0 in DIP28) is still in development, supposed to be out later this year. I have a vague memory of old Luminary having a DIP-packaged Cortex-M3, but if so it's been cancelled a long time ago. -a

It's rare to find interesting (to me) MCUs in DIP format these days. Example breakouts: http://www.delorie.com/electronics/rx/rx62n-breakout.html http://www.delorie.com/electronics/rx/rx62t-80-breakout.html http://www.delorie.com/electronics/r32c-breakout/ The RX is a 32-bit part, and the 62N has built-in host/device USB and ethernet MII. http://www.delorie.com/electronics/m16c-26-adapter/ a 16-bit MCU breakout specifically designed for breadboarding http://www.delorie.com/electronics/r8c-3mk/ DIP adapter for 16-bit R8C with host/device USB (the breakout only supports device as-is) http://www.delorie.com/electronics/usb-gpio/ MCU with an FT232R interface, can use plug-ins or wire-to-breadboard (example use: http://www.delorie.com/electronics/bin2seven/proto-all.html) http://www.delorie.com/electronics/gR8C/ Has a photo with various dip-packaged MCU adapters There are plenty of places online to have one-off or small-batch breakout/adapter PCBs made, if you don't mind soldering the chip to it. Solder once, then use it with your breadboard.

The Farnell pricing on the packaging variants which are currently available is very reasonable so I hope PDIP follows the same general pricing pattern when it becomes available. It's a pity it doesn't have USB device, but there are still a number of things I can use this device for.

Thanks also to everyone else for breakout board suggestions. For now, I would like to use continue using PDIP in my own circuits, but I agree with people here in that I think I am going to be forced into a breakout board type situation in the future as newer devices come along. And you are quite correct; it would not be too difficult to have a series of generic breakout boards made once I make that move.

If you want to play with the big boys, you've got to learn what the big boys know. With the number of devices within the soldering abilities of most beginners, using a 48 or 64pin tqfp will get you more and better devices. Why is dip the only game you want to play ?? I would really like to know what keeps you in the 1980s ? Thanks don'
