I am looking for an (8052-style?) flashable microcontroller that meets
the following requirements:

Necessary requirements:
- Cost: < $2 each in quantities 100+
- onboard crystal at 12MHz or faster
- DIP style mount (no SMT - Surface Mount Technology)
- 20 or greater inputs/outputs
- at least 1k of memory
- programmer for the chip costs < $100

Wishful requirements:
- serially programmable
- 2k memory or greater
- programmer for the chip costs <$50
- available from Digi-Key


I had my eye on the Phillips P89LPC930 (Digi-Key part number
568-1283-5-ND) but the only problem is it is SMT.  If you can find a
chip that does the same and costs the same as that chip and is DIP
then I will be very happy.

I'm sure there are a zillion chips out there that meet my requirements
so feel free to answer with several options.

Thanks!

or 16f84a if you dont need 20 lines (use some clever multiplexing!)

It looks like the 16f877a costs more than $2 each in quantities of 100
and doesn't have an on-board oscillator.
