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 previously selected Index register bank will also be restored during this instruction. The 4 bit content of the index register is unaffected. Intel products are not intended for use in medical, life saving, or life sustaining applications.

The effective address counter inrel decremented and program control is returned to the location saved by the forced JMS which occurred at the beginning of the interrupt routine. A code conversion is performed on the accumulator content, from 1 out of n to binary code. The first public mention of was an advertisement in the November 15, edition of Electronic News[7] though datasheer reports put daasheet date of first delivery as early as March It was introduced in Fetch indirect from ROM.

The RAM character is unaffected.

The LSB bit of the accumulator appears on O 0pin 16 of the If the result is zero, the next instruction after ISZ is executed. The 4 bit contents of index register 7 are logically “AND-ed” with the accumulator.

The 4 bit content of the designated index register is incremented by 1. Packaged in a pin ceramic dual in-line packagethe was the first commercially available computer processor designed and manufactured by chip maker Intelwhich had previously made semiconductor memory chips.

The accumulator is cleared.

If an interrupt routine wanted to make use of the latter eight registers, it was catasheet to the programmer to first save datashheet data held in them to intdl location, and then restore it before returning from the routine.


Archived from the original on This page was last modified on 13 Decemberat Program control is transferred to the instruction at that address on the same page same ROM where the JIN instruction is located. When Faggin designed the MCS-4 family, he also christened the chips with distinct names: It has 12 sq mm die size and 16 pins which fit in to a motherboard.

Select index register bank 1. The values to be set in the registers should be stored in the data area as the transferinterrupt controller or bus controller and can be directly accessed by the CPU.

It was the first commercially available microprocessor by Intel. Verify with your local Intel sales office that you have the latest data. No abstract text available Text: Converts the contents of the dwtasheet from a one out of four code to a binary code.

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 Stanfordand he had “played with it some” while he was there.

The 4 bits of status character 1 from the previously selected RAM register are transferred to the accumulator. When JIN is located at the address P H program control is datashedt to the next page in sequence and not to the same page where the JIN instruction is located. The address of the next instruction in sequence following JMS return address is saved in the push down stack.

Intel 4040

The new chip included a much larger stack 7 levels instead of 4. In the system design this should be designated as the RAM channel. One of them is used as the program counter, therefore nesting of JMS can occur up to 3 levels in and 7 levels in The plastic P variant. They invented the Microcontroller”.

The 4 bits of status character 2 from the previously selected RAM register are transferred to the accumulator. This article is still a stub and needs your attention. The Intel i is a 4-bit microprocessor introduced in by Intel as a successor to the Intel The actual instruction mix wasn’t specified, so without both source code and a list of instruction execution datasheett it’s impossible to be sure.

Intel has5. Write the dagasheet of the accumulator into the previously selected RAM status character 0. Three other CPU chip designs were done at about the same time: X 1 will contain the 4 bit accumulator contents.

Such a feat of integration was made possible by the use of the then-new silicon gate technology which allowed twice the number of random-logic transistors and an increase in speed dztasheet a factor of five compared to the datsheet technology.

Increment contents of register RRRR. The 4 bit content of the designated index register is loaded into the accumulator. In the lower-right corner of the CPU you can see the “F.

The 8 bit content of the designated index register pair is loaded into the low order 8 positions of the program counter.

Specifically, the first 2 bits of the address designate a RAM chip; the second 2 bits designate 1 out of 4 registers within the chip; the last 4 bits designate 1 out of eatasheet 4 bit main memory characters within the register.
