RE: [Sdcc-user] SDCC is ECE students projects (need a help)

[Story, L. <Lenny.Story@Alcatel.com>]

Phillips makes a chip which has onboard flash, and and built in Bootloader,
so you dont need to have an external programmer. A working circuit can be
built, and used with the freeware programming utility, with only a crystal,
caps, and a RS232 Charge pump (MAX233).

The Phillips 8051 is the idea chip... in my view...

P89C51RD2 - 64k Flash, 1K Ram.
