This period also saw considerable experimentation with various word lengths. Early on, 4-bit processors were common, like the Intel 4004, simply because making a wider word length could not be accomplished cost-effectively in the room available on the small wafers of the era, especially when the majority would be defective.
The die from an Intel 8742, an 8-bit microcontroller that includes a CPU running at 12 MHz, 128 bytes of RAM, 2048 bytes of EPROM, and I/O in the same chip Two ATmega microcontrollers. A microcontroller (MC, UC, or μC) or microcontroller unit (MCU) is a small computer on a single integrated circuit.
The history of computing hardware starting at 1960 is marked by the conversion from vacuum tube to solid-state devices such as transistors and then integrated circuit (IC) chips. Around 1953 to 1959, discrete transistors started being considered sufficiently reliable and economical that they made further vacuum tube computers uncompetitive .
Intel launches the Intel MCS-48 series of microcontrollers, the world's first microcontrollers (which combine a CPU with memory, peripherals, and input-output functions). [4] 1978: June: Product: Intel introduces the 8086 16-bit microprocessor, which becomes the industry standard (for the x86 instruction set). [6] 1979: November: Product
The 8049 has 2 KB of masked ROM (the 8748 and 8749 had EPROM) that can be replaced with a 4 KB external ROM, as well as 128 bytes of RAM and 27 I/O ports. [2] The microcontroller's oscillator block divides the clock input frequency by three and then further divides the result into five machine states.
The Cidco MailStation Mivo 100, first released in 1999, was a stand-alone portable email device, with a Z80-based microcontroller. [94] Texas Instruments produced a line of pocket organizers (ending in 2000) using Toshiba processors built around a Z80 core; the first of these was the TI PS-6200 [ 95 ] and after a lengthy production run of some ...
