Intel 8048 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?] (2000-06-01)
