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?]
- Intel 80486
- Intel 8051
processor A microcontroller developed by Intel in 1980 for use in embedded products and still (1999) one of the most popular microcontrollers. The 8051/8031 cores are used in over 100 devices from 10 independent manufacturers such as Dallas and Philips. [What is the difference between the 8031/8051/8052?] See also CAS 8051 Assembler, as31 assembler, 51forth. […]
- Intel 8080
processor The successor to the Intel 8008. The 8080 had a 16-bit address bus and an 8-bit data bus. It had seven 8-bit registers (six which could also be combined as three 16-bit registers), a 16-bit stack pointer to memory which replaced the 8008’s internal stack and a 16-bit program counter. It also had 256 […]
- Intel 8085
processor A microprocessor intended to be an improved Intel 8080, as was the Zilog Z80. (1994-10-31)
