Intel 8048
8048
<processor> The {microcontroller} used in {IBM PC} keyboards.
The 8048 was inspired by, and similar to, the {Fairchild F8}
microprocessor but, being a microcontroller, was designed for
low cost and small size. The 8048 has a modified {Harvard
architecture}, with program {ROM} on chip and 64 to 256 bytes
of {RAM} also on chip. I/O is mapped in its own {address
space}.
Though the 8048 was eventually replaced by the very popular
but bizarre {Intel 8051} and {Intel 8052}, even in 2000 it is
still very popular due to its low cost, wide availability, and
development tools.
[Was it really __the_first__ microcontroller? Are the ROM and
RAM both on-chip?]
