<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?]
