Intel 8048 definition
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?]
