Why specifically ARM7? ARM7 is pretty old at this point. Cortex-M is what you're looking for when you want ARM microcontrollers and aren't bound by legacy ARM7 software you would have to port. Well okay, they don't have the ARM instruction set as such and understand only Thumb2, but that is in the end mostly just a different encoding of the same instruction set.

If you need low pin count packages then boy did NXP announce some interesting chips for you. How about Cortex-M SoCs in SO20 and TTSOP20? I bet you're just going to love the one in a DIP28.

Seriously, if all you want is under 50 edge pins (something like QFP48) then there's lots of choice in the 32 bit ARM world.
