Intel (i) is an enhanced version of Intel microprocessor. According to Intel’s datasheet some microprocessors could operate in industrial. The Intel (i) is a 4-bit microprocessor introduced in by Intel as a successor to the Intel The i Datasheet. The Intel microprocessor was a revised and extended version of the Intel Datasheet ยท Intel MCS Prototype System Summary.

The following symbols and abbreviations will be used throughout the next few sections: Numerous versions of the Intel MCS-4 line of processors were produced. A more efficient addition routine might have been possible on the vs datadheetbut the extra instructions don’t suggest any obvious method for achieving this and appear to be focussed on addressing the earlier chip’s more obvious shortcomings, e. They invented the Microcontroller”. The 8 bit content of the index register is unaffected.

Except as provided in Intel ‘s Terms and Conditions of Sale for such products, Intel assumes no liability whatsoever, and Intel disclaims any express or implied warranty, relating to. Facts about ” – Intel “.

The CPU can directly address 4Keight bit instruction. The program counter address stack is pushed down one level. Execution of a return instruction BBL will cause the saved address to be pulled out of the stack, therefore, program control is transferred dxtasheet the next sequential instruction after the last JMS. When asked where he got the ideas for the architecture of the first microprocessor, Hoff related that Plessey”a British tractor company”, [9] had donated a minicomputer to Stanford inyel, and he had “played with it some” while he was there.

If ISZ is located on words and of a ROM page, when ISZ is executed and the result is not zero, program control is transferred to the 8-bit address on the next page in sequence and not on the same page where ISZ is located. Privacy policy About WikiChip Disclaimers. The 4 bit contents of index register 6 are logically “AND-ed” with the accumulator. The kntel register is set to zero in case of overflow.

The detailed design was done by Tom Innes Tinnes of Bristol. The ceramic C variant without grey traces.

4040 Datasheet PDF

When an instruction is to be stored in RAM program memory, it is written in two four-bit segments. The content of the previously selected RAM main memory character is transferred to the accumulator. If a borrow is generated, the carry bit is set to itnel otherwise, it is set to 1.

Verify with your local Intel sales office that you have the latest data. Intel Intel If an interrupt routine wanted to make use of the latter eight registers, it was up to the programmer to first save any data held in them to another location, and then restore it before returning from the routine. The also introduced interrupt support.

Federico Faggin proposed the project, formulated the architecture and led the design. The interrupt acknowledge line is cleared to V SS. The 4 bit content of the designated index register is added to the content of the accumulator with carry.


National Semiconductor was a second source manufacturer of theunder their part number INS Multi-media, recording and monitoring powered by Intel CPU and advanced graphics technologies.

The previously selected Index register bank will also be restored during this instruction. Tadashi Sasaki attributes the basic invention to break the calculator into four parts with ROMRAMshift registers and CPU to an unnamed woman from the Nara Women’s College present at a brainstorming meeting that was held in Japan prior to his first meeting with Robert Noyce from Intel, leading up to the Busicom deal. Read the contents of the previously selected ROM input port int the accumulator.

The 8 bit content of the designated index register pair is loaded into the low order 8 positions of the program counter. The 4 bit data in memory is unaffected. Write the contents of the accumulator into the previously selected RAM main memory character.

Intel 4004

The ceramic D variant. Information in this document is provided in connection with Intel products. Intel architectural block diagram. Up 1 level in stack. P rogram C ounter.

Intel – Wikipedia

Designate ROM bank 0. If the result is zero, the next instruction after ISZ is executed. The 4 bits of status character 1 from the previously selected RAM register are transferred to the accumulator. This instruction can be used only with the standard memory chip.
