It's only 30+ years old. But it's still being used. --Original 8748 User (precursor to the 8051) -- Randy Yates Digital Signal Labs http://www.digitalsignallabs.com

Every time you changed the code causing things to move, some of your branches broke because you couldn't branch across page boundaries. The UV erasable ones were something like $300 each when they first came out. The 8048 sure made the 8051 look great... -- Grant Edwards grant.b.edwards Yow! Am I in GRADUATE at SCHOOL yet? gmail.com

Relative to the Microchip part, this has a faster core, and finer Baud rate resolution and 2 UARTS.
