The Intel 4004, The First CPU (November 1971) http://www.cpushack.com/CPU/cpu1.html 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 740 kHz. 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 First Microcontroller (1974) http://www.cpushack.com/CPU/cpu1.html http://www.cpushack.com/CPU/cpu1.html Texas Instruments (TI) 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.
