hi..

If you have less requirements and a good controller.. try for 8051..
Both intel and Atmel have the same feature.. I prefer ATmel to INtel..
Its cheap and effective...
If u dont need external programmer kit u can go for AT89S51. else if u have a programmer kit u may go for AT89c51. There is a rate difference between the two.
Both have flash...

Hav nice time in projects..

Regards..
