The Intel 4004, The First CPU(Nov 1971)http://www.cpushack.com/CPU/cpu1.html • The first single chip CPU was the Intel 4004, a 4-bit processor meant for a calculator. It processed data in 4 bits, but its instructions were 8 bits long. Program and Data memory were separate, 1K data memory and a 12-bit PC for 4K program memory. There were also sixteen 4-bit (or eight 8-bit) general purpose registers. • The 4004 had 46 instructions, using only 2,300 transistors in a 16-pin DIP. It ran at a clock rate of 740kHz. • The 4040 (1972) was an enhanced version of the 4004, adding 14 instructions, larger (8 level) stack, 8K program space, and interrupt abilities.
TI TMS 1000, The FirstMicrocontroller (1974)http://www.cpushack.com/CPU/cpu1.html Texas Instruments followed the Intel 4004/4040 closely with the 4-bit TMS 1000, which was the first microprocessor to include enough RAM, and space for a program ROM, and I/O support on a single chip to allow it to operate without multiple external support chips, making it the first microcontroller.
