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 · Intel MCS Prototype System Summary.

4040 Datasheet PDF

The 4 bit contents of index register 4 are logically “OR-ed” with the accumulator. However, as project complexity increases, the various other support chips start to become useful.

This allows saving the command register values before processing the interrupt. The content of the previously selected RAM main memory character is added to the accumulator intle carry. For the selected chip itel register, however, status character locations are selected by the instruction code OPA.

The 4 bit content of the designated index register is loaded into the accumulator. From Wikipedia, the free encyclopedia.

The Intel was designed by physically cutting sheets of Rubylith into thin strips to lay out the circuits to be printed, a process made obsolete by current computer graphic design capabilities. The is part of the MCS-4 family of LSI chips that can be used to build digital computers with varying amounts of memory. A logic “0” is the most positive test input.


One of them is used as the program counter, therefore nesting of JMS can occur up to 3 levels in and 7 levels in 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. The result is placed in the accumulator and the carry flip-flop is unaffected.

This page was last edited on 1 Octoberat In the lower-right corner of the CPU you can see the “F. The RAM character is unaffected. Select index register bank 0.

datxsheet The ceramic C variant without grey traces. Within this group is contained a second group which is desinated supplemental group. Converts the contents of the accumulator from a one out of four code to a binary code.

These are the new instructions which have datasehet added to the The content of the accumulator is incremented by 1. Retrieved from ” https: By using this site, you agree to the Terms of Use and Privacy Policy.

Address 6, 84 loaded into PC; datasheft of SRC register sent out and the index register bank selection is restored. Faggin, the sole chip designer among the engineers on the MCS-4 project, was the only one with experience in metal-oxide semiconductor MOS random logic and circuit design. The 4 bit content of the index register is unaffected.


He also had the crucial knowledge of the new silicon gate process technology with self-aligned gateswhich he had created at Fairchild in In February Intel dxtasheet the microprocessor to the market.

He also led the MCS-4 project and was responsible for its successful outcome — The previously selected Index register bank will also be restored during this instruction. The 8 bit content of the index register is unaffected. The 4 bit contents of index register 6 are logically “AND-ed” with the accumulator. Federico Faggin proposed the project, formulated the architecture and led the design. They invented the Microcontroller”. BBL is used to return from inel main program.

The data present at the input lines of the previously selected ROM chip is transferred to the accumulator. White ceramic Intel C microprocessor with grey traces.
