what are the difference between AT89S51, and AT89S52

www.8052.com/.../113280
As we're waking up old threads, note that the "8052.com" domain name had been sold off - it is no longer a microcontroller forum!
The old 8052.com forum is now at http://www.8052mcu.com/
See http://www.8052mcu.com/forum/read/190875 for details.
