By Manufacturer
Fairchild
Fairchild produced a couple of different microprocessor designs the F8, the 9400, and the 100220. It also produced second source versions of the Motorola 6800,
Intel
Intel is a name that is closely associated with microprocessors. Intel’s microprocessors were certainly leaders in the micro revolution. The X86 architecture and IBM PC became the de facto standard for personal computing in the late 20th century. In addition, Intel produced several other micro-architectures that had varying degrees of success.
Motorola
Motorola’s microprocessors tended to be very innovative, but never seemed to capture large market share. The 6800 was a great start and 68000 was an incredible design. Other chip designs such as the 10800 were interesting as well. When Motorola joined forces with IBM and Apple for the PowerPC, the microprocessor innovation seemed to give …
National Semiconductor
General General Information The National Semiconductor IMP-16 is actually a two chip implementation, it’s heart is being the IMP-00A.The National Semiconductor IMP-00A bit-slice microprocessor was introduced to market in the beginning of 1973, this is just the fourth microprocessor (1st, Intel 4004, 2nd Intel 8008, 3rd Rockwell PPS-4). The IMP-00A is the first bit-slice microprocessor, …
NEC
NEC (Nippon Electric Company) was Japan’s first company to design their own microprocessor. NEC developed the NEC UPD751, a 4-bit microprocessor. NEC developed many other microprocessors and was an important second source supplied of Motorola 6800 and Zilog Z80 processors.
RCA
RCA started its microprocessor development with a two chip implementation of 1802, the 1801. The 1802 was the primary microprocessor architecture for RCA. It was created in radiation hardened versions for military and space applications.
Rockwell
Rockwell got an early start with microprocessors with the PPS-4. Rockwell later moved to second source the MOS 6502. Rockwell became the preferred supplier for some versions, even creating versions not offered by MOS.
Texas Instruments
Texas Instruments was locked in a race with Intel to create the first microprocessor. By most accounts Intel won with the 4004, but there are a few die hard TI fans who say the TMS1000 was first, because it was the first “computer on a chip” and that the 4004 was just a calculator chip. …
Western Digital
Western Digital’s 1st microprocessor, the 1600 was Implemented with 3 chips. The 1600 was a microprogrammable CPU. The naming convention for the 1600 was a little confusing. The 1611 Control Chip was an ALU and 1621 Data Chip was the CU. The micro-instructions data were stored in the 1631 Microms (contraction of Micro ROM). The 1611 …
